DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving apparatus and method, a transmitting apparatus and method, a communication system, a recording medium, and a program, and more particularly, to a receiving apparatus and method for transmitting or receiving electronic mail, a transmitting apparatus and method, The present invention relates to a communication system, a recording medium, and a program.

[0002]

2. Description of the Related Art A system for transmitting and receiving text-based data via a network or the like, that is, an electronic mail system is widely used.

[0003] Electronic mail (hereinafter simply referred to as mail)
Receiving device displays the received mail in text.

There are times when a mail sender wants a mail reader to perform some action.

[0005] In JP-A-2000-47955 and JP-A-11-65964, data used for executing an application program is attached to a mail in order to cause a recipient of the mail to execute some processing or action. The invention that transmits and receives data is disclosed.

[0006]

However, the desired action of the mail sender is not always executed.

[0007] For example, if the other party who has received the mail reads the mail, understands the contents of the mail correctly, and does not take the action, the desired action of the sender is not executed.

Similarly, when data is attached to a mail, the action is not executed unless an application program corresponding to the attached data is executed on the receiving side.

For example, when a job request that must be performed by a predetermined deadline is sent by e-mail, the mail sender instructs the mail reader to read the mail and perform the work by the deadline date. Acknowledgment, for example, Micros
We expect to receive a reply notifying you that you have registered with the application program, such as oft Outlook ™ or ToDo, which is the basic software of Palm OS, to register the subject of the job and the deadline.

However, according to the conventional technology, in order for the sender of the e-mail to receive an acknowledgment reply, the reader must correctly understand the contents of the received e-mail and register the subject of the job such as ToDo and the deadline thereof. You have to start up the application program that you want to register, register it correctly, and in the reply e-mail, correctly indicate that you accepted your work and reply to the sender.

There is no guarantee that the mail sender will receive a reply.

In such a case, a possible solution is to attach an application program that returns a reply as described above and have the reader execute the program. In this case, the reader must start the application program.

When playing a game such as Othello via e-mail, the Othello board is described with + or-symbols,
In addition, it is possible to proceed with the game by describing frames with black or white circle symbols and sending them as text.

However, when a new hand is inserted,
Since the user shifts the arrangement of the symbols, it is necessary to correct the shift.

[0015] The content of the game screen is, for example, PowerPoi
It is also conceivable that the generated file is described in nt (trademark) (application program of Microsoft Corporation) and attached to an e-mail and transmitted. In this case, the e-mail reader must start the corresponding application program one by one, and unless the user has the corresponding application program, he cannot see the game screen.

In addition, in the case of a game such as Othello, the user must execute a process of determining whether or not a newly input hand has been hit in a correct place according to rules, and turning over a frame with the new hand. The problem is that mistakes often occur.

The present invention has been made in view of such a situation, and allows a mail reader to be quickly and reliably provided to a mail reader.
The purpose is to cause a mail sender to execute a desired action.

Next, transmission and reception of mail via the Internet 4 will be described.

The mechanism for sending or receiving a mail via the Internet 4 is very similar to the mechanism for sending a mail such as a postcard. In the case of mail, Write a letter, 2. 2. Post to the post. 3. Transfer between post offices; One letter arrives at the recipient through the four steps of delivering to the mailbox.

In the case of mail via the Internet 4, 1. Write an email on the email sending and receiving program,
2. 2. Press the send button of the mail sending and receiving program.
3. Transfer between mail servers After going through the four steps of pressing the receive button of the mail sending and receiving program,
The email reaches the other party.

The mail sending / receiving program is a program for writing a mail and sending it to the other party, or receiving the mail sent by the other party. The mail sending / receiving program is also called a mailer, and has a function corresponding to a post and a mailbox.

Most mail sending / receiving programs have an editor function for displaying mail on a screen or writing mail. The user operates the mail sending / receiving program to send or receive mail.

As a typical mail sending / receiving program,
Microsoft's OutlookExpress (TM), Qualcomm's Eudora Pro (TM), and free software Becky! InternetMail or Al-Mail32.

The mail server plays the role of a post office, so to speak. The mail server receives the mail sent by the mail sending / receiving program, and sends the mail to the mail sending / receiving program. As a typical mail server program,
There is sendmail (trademark) of Sendmail Corporation.

The mail server has three main roles. First, the mail received from the mail sending and receiving program,
Properly sending to other mail servers. Second
Is to organize and manage mails received from other mail servers by destination (user). Third, sending the managed mail to the mail sending / receiving program in response to a request from the mail sending / receiving program.

The procedure for the mail sending / receiving program to send mail to the mail server is different from the procedure for the mail server to send mail to the mail sending / receiving program, and the communication procedure is different.

The communication procedure is called a protocol. The processing by which the mail sending and receiving program sends mail to the mail server and the processing by which the mail server sends mail to the mail server include SMTP (Simple Mail Transcript).
sfer protocol) is widely used.

The process of receiving a mail from the mail server by the mail sending / receiving program includes POP3 (Post Office
Protocol Version 3) is widely used.

In the mail server, the port corresponding to SMTP and the port corresponding to POP3 are different from each other. When sending mail, the mail sending and receiving program communicates with the mail server via the port corresponding to SMTP,
When receiving mail, it communicates with the mail server via the port corresponding to POP3.

In the case of mail, a letter sent from a foreign country is stamped for each country that has passed. Similarly, the mail is also marked with a postmark.

When a mail is transmitted, postmark information is sequentially added to the head of the mail text each time the mail passes through the mail server. Since attached to the head, this postmark information is called a header.

The header is roughly composed of three blocks. The block attached to the mail transmission / reception program is arranged in the lowermost part (the part close to the text), and the blocks attached to the mail server are arranged in the two upper parts.

The header stores new information at the top.

The header information attached to the mail sending / receiving program is composed of the same information as the address of the letter. From stores the mail address of the sender, To stores the mail address of the destination, and Subject stores the title.

Of the blocks attached by the mail server, Re
In ceived, a time stamp is stored. form stores the name of the mail server that passed.

The mail server sends this mail
Add Received block. Therefore, the mail server through which the mail has passed can be known by checking the description of the Received block in order from the bottom to the top.

Next, the setting of the mail transmission / reception program will be described. The information that must be set correctly in order to send mail is the e-mail address corresponding to the mail sending / receiving program and the host name of the mail server corresponding to SMTP.

The e-mail address corresponding to the mail transmission / reception program is a source address corresponding to the sender name. When the e-mail address corresponding to the e-mail transmission / reception program is not set, the recipient of the e-mail cannot know the sender, and when the destination is unknown, the e-mail cannot be returned.

The mail sending / receiving program inserts an electronic mail address corresponding to the mail sending / receiving program into the From line in the header. The e-mail address corresponding to the mail transmission / reception program is also used as a destination when the other party writes a reply. Depending on the mail transmission / reception program, the destination of the reply can be changed by setting the item of the reply address.

As the host name of the mail server corresponding to SMTP, the host name of the mail server to which the mail sending / receiving program sends mail is set. When sending a mail, the mail sending / receiving program sends the mail to the mail server based on the host name of the mail server corresponding to the SMTP. The host name is described as, for example, mailserver.so-net.ne.jp.

The e-mail address and the host name are described based on the domain name. In the domain name, the country name, the type of organization, and the company name are represented by connecting “.”. In a domain name, a larger section is located later.

The e-mail address is the name of the user,
It is indicated by attaching "@" as a delimiter and further connecting a domain name.

The host name is expressed by adding "." As a delimiter to the server name, and further connecting the domain name.

The e-mail address or host name is a unique e-mail address or host name as described above.

Upper and lower case letters are used for the domain name of the e-mail address and the host name, but these are not distinguished.

Next, transmission of mail to the mail server by the mail sending / receiving program will be described. The mail sending / receiving program must obtain the IP address corresponding to the host name when sending mail. The IP address is described by a combination of a numeral and “.”, For example, 192.168.0.1.

The DNS is a system for converting a host name into an IP address. Internet 4 has several DNs
S server is installed. When a host name is sent to one of the DNS servers, the DNS server returns an IP address corresponding to the host name.

For example, the DNS server 6-1 in FIG. 1 records an IP address aaaa in association with the host name A.

The mail sending / receiving program sends the I / O of the mail server from the DNS server immediately before accessing the mail server.
Ask your P address.

Next, a procedure for sending a mail from the mail sending / receiving program to the mail server will be described. The mail sending / receiving program and the mail server send mail from the mail sending / receiving program to the mail server according to the SMTP procedure.

The procedure of SMTP is TCP (Transmission Control).
l Protocol) setup, calling the mail server, preparing for transmission, notification of destination, transmission of text, confirmation of termination,
And termination of TCP. The processing of calling the mail server, preparing for transmission, notifying the destination, transmitting the text, and confirming the end are all composed of a request from the mail transmission / reception program and a reply from the mail server.

In the SMTP processing, the mail transmission / reception program and the mail server communicate with each other using a command statement and a reply code. For example, the command statement “RCPT from:
y@so-net.ne.jp ", the RCPT is a command to notify the mail destination, and the mail destination is y@so-net.ne.jp.
jp.

In the reply code, for example, “Yes”
250. To explain some of the reply codes, 251
Indicates "No such user exists", 450
Indicates "Mailbox is in use" and 451 indicates "
452 indicates "Insufficient resources for processing" and 501
Indicates "The command syntax is incorrect."
Indicates "command not available" and 550 indicates "mailbox does not exist".

The mail has a broadcast function. The lifetime broadcast function is a function to send an e-mail with the same text to many people.

For example, if a plurality of mail addresses are described in the To line of the header, the mail sending / receiving program
The process of transmitting the PT command is repeated for each address described in the mail address.

The Cc (carbon copy) line or B
Broadcasting can also be performed using a special header such as a cc (blind carbon copy) line.

When a mail is transmitted using the Cc line or the Bcc line, the recipient of the mail knows that a copy of the mail has been received because his or her address is not described in the To line of the header. be able to.

When sending an e-mail using the Cc line,
The header stores the mail address of the other party.
When the mail is transmitted using the Bcc line, the mail transmitting / receiving program deletes the Bcc line from the header after transmitting the RCPT command, and transmits the text. Bcc
Sending an e-mail using a line is effective when you do not want to inform the other party of the broadcast destination.

Next, a process in which the mail server searches for a mail server near the destination and transfers the mail server will be described. The process of transferring mail from the mail server to the mail server,
It is executed according to the procedure of SMTP.

In the process of transferring mail from the mail server to the mail server, the mail server sending the mail cuts out the domain name from the mail destination and sends the cut out domain name to the DNS server.

Since the DNS server records the relationship between the domain name and the host name of the mail server as an MX record, it sends the host name of the mail server corresponding to the domain name to the mail server that sent the domain name. .

For example, the DNS server 6-2 in FIG. 1 records the host name B in correspondence with the domain name BBB.

The mail server having received the host name transmits the host name to the DNS server.

Since the DNS server records the relationship between the host name and the IP address as an A record, the DNS server transmits the IP address corresponding to the host name to the mail server that transmitted the host name.

For example, the DNS server 6-2 in FIG. 1 records the IP address bbbb in association with the host name B.

The mail server that has transmitted the IP address transmits the mail to the mail server corresponding to the domain name of the mail destination based on the above-described SMTP procedure.

The mail server can broadcast mail using a mailing list. When broadcasting mail using a mailing list, the alias function is used.

The mail server using the alias function records a plurality of addresses in advance in groups corresponding to predetermined mail addresses (representative addresses). Upon receiving the mail addressed to the representative address, the mail server retransmits a copy of the mail to all of the plurality of addresses recorded corresponding to the representative address.
The mail server sends mails one after another to the registered mail addresses without rewriting the header.

The mail server corresponding to the domain name stores the received mail in a mailbox called spool. The mail server manages the mail for each user, and distributes the mail when the receiving button of the mail sending / receiving program of the user corresponding to the destination is pressed.

The reason that the mail server does not transmit mail to the mail transmission / reception program based on SMTP may be that the device executing the mail transmission / reception program is not operating or is not connected to the Internet 4. It is.

The mail server sends mail to the mail sending / receiving program based on POP3. POP3 procedure is TC
Set up P, call mail server, authenticate user, check mailbox contents, check number of incoming calls,
The process consists of receiving the body text, requesting deletion, confirming termination, and terminating TCP. The process of calling the mail server, authenticating the user, checking the contents of the mailbox, checking the number of incoming calls, receiving the text, requesting deletion, and checking the end are all requests from the mail sending / receiving program and the reply from the mail server. It consists of.

The command text and reply code in POP3 are different from the command text and reply code in SMTP.

In POP3, mail reception processing is not executed unless the user is authenticated by the user ID and password registered in the mail server in advance.

Is a program for executing a process corresponding to the input of the jog dial 23.

The library 103 stores a plurality of processing routines used by an application program such as the mail transmission / reception program 104.

The mail sending / receiving program 104 includes the cradle 2-1 or 2-2, the personal computer 3
-1 or 3-2 and a program for sending or receiving a mail via the Internet 4.

The configuration of the program shown in FIG. 7 is the same as the configuration of a conventional program of a device for transmitting and receiving mail.

FIG. 8 is a diagram for explaining a program executed by the PDA 1 for transmitting a mail or receiving a mail. When receiving the mail from the mail server 5-2, the mail transmission / reception program 104 causes the display unit 11 to display, for example, an image shown in FIG. When displaying the received mail, the mail sending / receiving program 104 supplies the received mail to the interpreter 106.

The library 105 includes an interpreter 106
Contains the routines used when executing scripts.

The interpreter 106 is a program plugged into the mail transmission / reception program 104, extracts a script included in the mail, and executes the extracted script. For example, the interpreter 106
In response to the execution of the script, the driver 102-1
A predetermined image is displayed on the display unit 11, and the driver 102-
3 causes the sound reproducing unit 42 to reproduce a predetermined sound.

The interpreter 106 is connected to the display unit 11
Alternatively, the driver 102-1 to 102-4 corresponding to the device such as the sound reproducing unit 42 executes processing such as display or sound reproduction, so that various devices operating according to the execution contents of the script are stored in the PDA 1. Even if incorporated, the control of the device by the interpreter 106 is executed reliably and accurately.

The mail sending / receiving program 104
When the script is included in the mail to be displayed, the interpreter 106 may be activated and the library 105 may be loaded.

FIG. 10 is a diagram for explaining the structure of the interpreter 106 in more detail. The interpreter 106 includes a syntax analysis module 121, an execution module 122, and an output module 123.

For example, as shown in FIG. 11, when the mail transmission / reception program 104 attempts to display the mail 151, the syntax analysis module 121 receives the mail 151 from the mail transmission / reception program 104 and is included in the received mail 151. The extracted script is extracted and supplied to the execution module 122.

FIG. 12 is a diagram showing an example of the structure of a mail 151 transmitted or received by the PDA 1. When the script is stored in the mail 151, the script is stored after the mail body. When the stored script requires data, the mail 151 stores data necessary for execution of the script by the interpreter 106 following the script.

The syntax analysis module 121 sends the mail 15
When data is stored together with the script in 1, the data is extracted together with the script, and the extracted data is supplied to the execution module 122 together with the script.

FIG. 13 is a view for explaining the flow of processing of the interpreter 106 when the mail 151 stores a script. When the script is extracted from the mail 151, the syntax analysis module 121 supplies the extracted script to the execution module 122.

The execution module 122 that has received the supply of the script executes the script. Output module 12
3 displays an image, outputs sound, or outputs data 171 in accordance with the result of executing the script.
Is stored in the EDO DRAM 34, for example.

On the other hand, when the syntax analysis module 121 does not extract the script from the mail 151 (when the script is not included in the mail 151), as shown in FIG. Is executed by the mail transmission / reception program 104, and normal mail processing is executed. At this time, the mail transmission / reception program 104 supplies text data 191 corresponding to the body of the mail 151 to the driver 102-1. The driver 102-1 causes the display unit 11 to display the body of the mail 151 based on the text data 191.

FIG. 15 shows a mail 151 for executing Othello.

As shown in FIG. 19, when the user inputs a new hand, the execution module 122 executes ontap ().
The method gets the coordinates on the Othello board where the new hand was entered. The execution module 12 determines, using the check () method, whether or not the coordinates corresponding to the new hand satisfies the requirements specified in the Othello rule, and determines that the coordinates do not satisfy the requirements specified in the Othello rule. If so, an error is notified by the confirm () method (an error message is displayed on the display unit 11), and the execution of the ontap () method is repeated.

If it is determined that the new hand satisfies the requirements specified in the Othello rules, the execution module 1
In step 22, the face of the frame is updated by the update () method, as shown in the example of FIG. Output module 123
Executes a process of sending an e-mail to the other party by the sendmail () method, as shown in an example in FIG.
Processing ends with the t () method.

Next, mail transmission processing by the PDA 1 executing the mail transmission / reception program 104 will be described with reference to the flowchart in FIG. In step S11, the mail sending / receiving program 104 causes the USB interface 36 to transmit the host name corresponding to the mail server 5-1 to the DNS server 6-1 via the cradle 2, the personal computer 3, and the Internet 4, An IP address corresponding to the mail server 5-1 is obtained from the server 6-1.

The processing of steps S12 to S18 is executed, for example, based on the SMTP procedure.

In step S12, the mail sending / receiving program 104 causes the USB interface 36 to connect to the mail server 5-1 by specifying an IP address via the cradle 2, the personal computer 3, and the Internet 4. In step S13, the mail sending / receiving program 104
6 calls the mail server 5-1 via the cradle 2, the personal computer 3, and the Internet 4 (calls a mail server program (for example, sendmail (trademark) or the like) executed by the mail server 5-1).

In step S14, the mail sending / receiving program 104 causes the USB interface 36 to make the mail server 5-1 prepare for sending the mail (procedure for sending the mail to the mail server program executed by the mail server 5-1). Will be notified). In step S15, the mail sending / receiving program 104
Notifies the USB interface 36 of the destination (mail address) of the mail to be transmitted to the mail server 5-1.

In step S16, the mail sending / receiving program 104 causes the USB interface 36 to send mail to the mail server 5-1. Step S17
, The mail transmission / reception program 104 causes the USB interface 36 to confirm completion of processing with the mail server 5-1.

In step S17, the mail sending / receiving program 104 causes the USB interface 36 to disconnect from the mail server 5-1 and the process ends.

As described above, the PDA 1 is connected to the mail server 5-
1 can send an email.

The process by which the mail server 5-1 transfers the mail to the mail server 5-2 is the same as the mail transmission process except for the process of obtaining the host name corresponding to the destination of the mail. Is omitted.

Next, mail reception processing by the PDA 1 executing the mail transmission / reception program 104 will be described with reference to the flowchart in FIG. In step S31, the mail transmission / reception program 104 causes the USB interface 36 to transmit the host name corresponding to the mail server 5-2 to the DNS server 6-2 via the cradle 2, the personal computer 3, and the Internet 4, An IP address corresponding to the mail server 5-2 is obtained from the server 6-2.

The processing of steps S32 to S40 is executed based on, for example, the procedure of POP3.

In step S32, the mail transmission / reception program 104 causes the USB interface 36 to specify the IP address via the cradle 2, the personal computer 3, and the Internet 4 to connect to the mail server 5-2. In step S33, the mail transmission / reception program 104
6 calls the mail server 5-2 via the cradle 2, the personal computer 3, and the Internet 4.

In step S34, the mail sending / receiving program 104 sends the PDA 1 to the USB interface 36.
The user ID and the password of the user are transmitted to the mail server 5-2 via the cradle 2, the personal computer 3, and the Internet 4, and the mail server 5-2 executes the user authentication process.

In step S35, the mail transmission / reception program 104 causes the mail interface 5-2 to check the contents of the mail box (where the mail addressed to the user of the PDA 1 is stored) in the USB interface 36.

[0177] In step S36, the mail transmission / reception program 104 connects the PDA 1 to the USB interface 36.
The number of incoming e-mails to the user is transmitted to the mail server 5-2, and the number of incoming e-mails is received.

In step S37, the mail sending / receiving program 104 causes the USB interface 36 to send the mail addressed to the user of the PDA 1 to the mail server 5-2 and to receive the sent mail. In step S38, the mail transmission / reception program 104 causes the USB interface 36 to request the mail server 5-2 to delete the mail addressed to the user of the PDA 1. Mail server 5-2
Deletes the email addressed to the user of PDA1.

In step S39, the mail transmission / reception program 104 causes the USB interface 36 to confirm the end of processing with the mail server 5-2.

In step S40, mail sending / receiving program 104 causes USB interface 36 to disconnect from mail server 5-2, and the process ends.

As described above, the PDA 1 is connected to the mail server 5-
From 2, it is possible to receive a mail addressed to the user of the PDA1.

Next, the mail sending / receiving program 104 and the interpreter 106, which are executed when the mail sending / receiving program 104 displays the received mail, are executed.
The script processing of the PDA 1 will be described with reference to the flowchart of FIG. In step S51, the mail sending / receiving program 104 reads the received mail 151.

In step S52, the mail sending / receiving program 104 determines whether or not the read mail 151 includes a script. If it is determined that the script is included, the process proceeds to step S53, where the interpreter 106 to start. Mail sending and receiving program 1
04 interprets the read mail 151 into the interpreter 106
To supply.

The interpreter 106 may be activated in advance together with the mail transmission / reception program 104.

At step S54, the interpreter 1
The syntax analysis module 121 of 06 extracts a script included in the mail 151 based on the description of the mail 151. In step S55, the execution module 122 of the interpreter 106 executes the extracted script.

At step S56, the interpreter 1
The output module 123 executes display or audio output processing according to the result of the execution of the script. In step S57, the mail transmission / reception program 104 ends the interpreter 106, and the process ends.

If it is determined in step S51 that the script is not included, the processing corresponding to the script is not necessary, so that steps S53 to S5
7 is skipped, and the process ends.

As described above, when the script is included in the mail 151, the PDA 1 activates the interpreter 106 and executes the processing corresponding to the script.

Note that the processing in step S52 is performed by the syntax analysis module 12 of the interpreter 106 that has been started in advance.
1 may be executed.

Next, the Othello process, which is a more specific example of script execution, will be described with reference to the flowchart in FIG. In step S71, the mail sending / receiving program 104 reads the received mail 151.

At step S72, the mail transmission / reception program 104 starts the interpreter 106. In step S73, the output module 123 of the interpreter 106 causes the display unit 11 to display the Othello board and the frame.

In step S74, the execution module 122 determines whether a new hand has been input. If it is determined that no new hand has been input, the execution module 122 proceeds to step S74 until a new hand is input. And the process of the determination is repeated.

If it is determined in step S74 that a new hand has been input, the process proceeds to step S75, where the execution module 122 reads the coordinates of the new hand (indicating the position on the Othello board). In step S76, the execution module 122 determines whether the new hand satisfies the requirements specified in the Othello rule, and determines that the new hand satisfies the requirements specified in the Othello rule. If so, the flow advances to step S77 to place a frame at the position of the Othello board corresponding to the new hand.

In step S78, the execution module 122 updates the face of the frame, such as turning over a predetermined frame. In step S79, the output module 123
Displays the Othello board and the frame on the display unit 11.

In step S80, the output module 123 causes the USB interface 36 to communicate with a new hand. In step S81, the mail sending / receiving program 104 ends the interpreter 106, and the process ends.

If it is determined in step S76 that the new hand does not satisfy the requirements specified in the Othello rule, the process proceeds to step S82, where the output module 12
3 displays an error on the display unit 11 to notify the user of the error, and the procedure returns to step S74 to repeat the process from the input of a new hand.

As described above, the PDA 1 executes Othello processing based on the script included in the mail 151.

As described above, when the user attempts to read the mail 151, the PDA 1 executes the action desired by the sender of the mail 151. When the user does not read the mail 151, the PDA 1 does not execute the script included in the mail 151, so that the processing load of the script can be minimized.

Since the PDA 1 can execute various processes corresponding to the description of the script only by executing the interpreter 106, the data attached to the mail is compared with the case where the data is attached to the mail and transmitted. There is no need to store a large number of application programs corresponding to the types.

Further, since the interpreter 106 executes the script, if the interpreter 106 is securely implemented, the process can be executed more safely than when the execution program attached to the mail is executed as it is. .

Next, a more detailed configuration of the interpreter 106 will be described.

FIG. 30 is a diagram showing an example of a more detailed configuration of the interpreter 106. As shown in FIG.

The mail parser 502, decoder 503, parser 505, data constructor 517, encoder 518, and mail generator 519 shown in FIG.
Corresponding to the syntax analysis module 121.

The script interpreter 506 in FIG.
Authentication encryption unit 507, resource access manager 50
8 and the storage module 511 correspond to the execution module 122 in FIG.

The I / O (Input / Output) module 510 in FIG. 30 corresponds to the output module 123 in FIG.

The mail transmission / reception program 104 supplies the mail 151 to be opened to the mail parsing unit 502 via the mail transmission / reception program plug-in interface 501, or acquires the mail 151 generated from the mail generation unit 519. I do.

The mail syntax analysis unit 502 analyzes the syntax of the mail 151 supplied from the mail transmission / reception program 104 via the mail transmission / reception program plug-in interface 501, and extracts a script and data from the mail 151. Mail parsing unit 502
Supplies the script and data extracted from the mail 151 to the decoder 503.

A script is a type of program consisting of a series of instructions in which the processing procedure is described by character codes such as alphanumeric codes.

[0256] The decoder 503 decodes, for example, data encoded by a system such as Base64. Base64
Is an encoding method of binary data for converting data or a program into a sequence of 64 types of ASCII codes in order to transmit data or a program via a network transmitting only 7-bit data.

[0257] Note that the decoder 503 may decode an encoded script.

The decoder 503 is connected to the interface 50
4 to supply the script to the parsing unit 505,
The decrypted data is supplied to the script interpreter 506.

The syntax analyzer 505 replaces a predetermined character string included in the script with an intermediate code that can be processed by the script interpreter 506. Here, when the intermediate code is roughly divided, generally,
(1) a lexical sequence such as a lexical analysis result or a generated lexical sequence; (2) a parse tree or a parse tree generated as a result of the parse analysis; a tree structure such as a Polish notation; (3) a triplet ,
The intermediate code is classified into a format similar to a machine language such as a virtual machine code called a four-tuple. In this specification, this intermediate code is used in the meaning of a parse tree.

In the Java language, the above (3) is called "byte code".

The intermediate code is an intermediate code temporarily created for convenience in the process of converting the original source code into the final executable form in the software program. By finely separating the conversion process from the source to the target in this way, it becomes easy to make the language processing system correspond to a plurality of platforms (targets).

For example, in Java, the source code is
Once converted to an intermediate code called bytecode,
The converted intermediate code is stored on the WWW server. The WWW server sends this bytecode to the WWW browser on the client side and sends it to the Java VM (Java Virt
ual Machine) interprets and executes the bytecode.
In this case, since the Java VM absorbs the differences between the platforms (the differences between the CPU and the operating system), the bytecode itself does not depend on the specific platform. In this way, a platform-independent program environment is realized in Java while reducing the load imposed on execution (conversion from bytecode to executable code).

In other high-level language compilers, the source code is not directly converted into an execution program (usually a binary code that can be interpreted by the CPU), but is converted into an intermediate code having a higher degree of abstraction than the actual machine. After conversion (there is no need to worry about the limitations of the actual machine architecture, etc., it is easy to optimize the code, etc.), and then a method of generating a final executable binary code is often used.

The syntax analyzer 505 supplies a script in which a predetermined character string is replaced with an intermediate code to the script interpreter 506.

The script interpreter 506 supplies the script to the authentication encryption unit 507, and the script
7 makes the script determine the validity.

The authentication encryption unit 507 applies a hash function such as MD (Message Digest) 5 to the script to calculate a hash value corresponding to the script.
The authentication encryption unit 507 determines whether the calculated hash value and the data for authentication included in the script are the same.

FIG. 31 shows an example of a mail 151 including a script storing data for authentication.

In the mail 151 shown in FIG. 31, "<S
IGNATURE> ”and“ </ SIGNATURE> ”are data for authentication such as“ 347a9d8684ab96533fb6b51906fdacf9 ”.

[0269] An electronic signature or a certificate may be stored in the mail 151, and the authentication encryption unit 507 may be authenticated based on the electronic signature or the certificate.

If it is determined that the calculated hash value is the same as the authentication data, the authentication encryption unit 507 converts the data indicating that the script is valid, since the script has not been altered, into the script. It supplies to the interpreter 506.

If it is determined that the calculated hash value and the data for authentication are not the same, the authentication encrypting unit 507 sends data indicating that the script is not valid, since the script has been altered, to the script interpreter 5.
06.

The script interpreter 506 sends data indicating that the script is not valid, to the authentication encryption unit 50.
When supplied from 7, do not execute the script.

As described above, even if the transmission medium of the script is changed, the interpreter 106 can execute the script without changing the whole if only the part that depends on the transmission medium is changed.

Next, a process of executing a script attached to an electronic mail by the interpreter 106 shown in FIG. 30 will be described with reference to flowcharts of FIGS.

In step S501, the mail transmission / reception program 104 determines whether or not the mail 151 with the script attached is to be displayed. If it is determined that the mail 151 with the script attached is not to be displayed. Returning to step S501,
The determination process is repeated.

If it is determined in step S501 that the mail 151 to which the script is attached is to be displayed, the flow advances to step S502, and the mail transmission / reception program 104 causes the mail 151 to be opened.
Is supplied to the mail parsing unit 502 via the mail transmission / reception program plug-in interface 501.

In step S503, the mail syntax analysis unit 502 extracts a script and data necessary for executing the script from the mail 151 obtained from the mail transmission / reception program 104. Data necessary for executing the script includes, for example, data corresponding to the value of the program counter or the value of the stack pointer, indicating the execution state of the script when the script is interrupted, data indicating the arrangement of frames in the Othello game, schedule Data to specify the date and time to check, data indicating the item to be added to the ToDo list and the deadline, or data included in the electronic business card.

In step 05, a predetermined character string of the script supplied from the decoder 503 is replaced with a character string that can be interpreted by the script interpreter 506. The syntax analysis unit 505 supplies the script in which a predetermined character string has been replaced to the script interpreter 506.

[0334] In step S508, the script interpreter 506 converts the script into an authentication encryption unit 507.
To make the authentication encryption unit 507 confirm the validity of the script. The authentication encryption unit 507 extracts, for example, authentication data included in the script supplied from the script interpreter 506, and generates a hash value by applying a hash function to the script.
The authentication encryption unit 507 determines the validity of the script based on whether the extracted authentication data and the generated hash value are the same.

The authentication encryption unit 507 supplies data indicating whether the script is valid or not to the script interpreter 506.

In step S509, the script interpreter 506 determines whether the script is valid based on the data supplied from the authentication encryption unit 507. If the script is determined to be invalid, the script The process ends without executing the script because it has been modified.

If it is determined in step S509 that the script is valid, the flow advances to step S510, where the script interpreter 506 executes the script.

In step S511, the script interpreter 506 determines whether input / output, storage or reading of information, or access to an external application program has been requested by executing the script. If it is determined that storage or reading of information or access to an external application program has been requested, the process advances to step S512 to execute the script interpreter 506.
Causes the resource access manager 508 to execute input / output, storage or reading of information, or access of an external application program.

[0339] In step S513, the resource access manager 508 determines whether or not an input / output has been requested. If it is determined that the input / output has been requested, the process proceeds to step S514, where the input / output is transmitted to the I / O module 510. Is displayed on the display unit 21 to determine whether or not to execute input / output based on the operation of the user.

If it is determined in step S514 that input / output is to be performed, the process advances to step S515, where the resource access manager 508 determines whether the I / O module 5
10 to execute input / output processing such as displaying an image, and the procedure proceeds to step S516.

If it is determined in step S513 that no input / output has been requested, no input / output processing is necessary, so that steps S514 and S515 are skipped, and the procedure proceeds to step S516.

If it is determined in step S514 that the input / output is not to be performed, the input / output processing must not be performed, and the processing in step S515 is skipped.
The procedure proceeds to step S516.

In step S516, the resource access manager 508 determines whether storage or reading of information has been requested. If it is determined that storage or reading of information has been requested, the flow advances to step S517 to execute I / O A dialog box is displayed on the display unit 21 for allowing the user to input whether or not the module 510 is to store or read the information, and whether to store or read the information based on the operation of the user. Is determined.

If it is determined in step S517 that storage or reading of information is to be executed, step S517
Proceeding to 518, the resource access manager 508
The storage module 511 is caused to execute a process of storing or reading information, such as storing data in the Flash ROM 33, and the procedure proceeds to step S519.

If it is determined in step S516 that storage or reading of information has not been requested, the processing of storing or reading information is not necessary, so that the processing of step S517 and step S518 is skipped, and the procedure proceeds to step S516. Proceed to S519.

If it is determined in step S517 that information storage or readout is not to be performed, information storage or readout processing must not be performed, so that step S518 is skipped and the procedure proceeds to step S519. move on.

[0347] In step S519, the resource access manager 508 executes the schedule book program 5
12, it is determined whether or not access to an external application program such as the address book program 513, the memo pad program 514, the TODO book program 515, or the application program 516 is requested, and the access to the external application program is requested. If it is determined that the access has been made, the process proceeds to step S520, where a dialog box is displayed on the display unit 21 for allowing the user to input whether or not the I / O module 510 accesses the external application program. It is determined whether or not to access an external application program based on the operation.

If it is determined in step S520 that access to an external application program is to be executed, the flow advances to step S521, where the resource access manager 508 accesses the external application program, and the flow advances to step S522.

If it is determined in step S519 that access to the external application program has not been requested, access to the external application program is not required, and therefore, step S520 is performed.
And the process of step S521 is skipped, and the procedure proceeds to step S522.

If it is determined in step S520 that the access to the external application program is not to be executed, the process of accessing the external application program must not be executed.
Step 21 is skipped, and the procedure proceeds to step S52.
Proceed to 2.

[0351] In step S522, the resource access manager 508 sets the script interpreter 50
6, the result of input / output, storage or reading of information, or access of an external application program is supplied.

In step S523, the script interpreter 506 determines whether or not to transmit the execution result of the script by e-mail based on the operation of the user or the description of the script, and transmits the execution result of the script by e-mail. If it is determined to transmit, step S524
The script interpreter 506 supplies the data constituting unit 517 with data that is attached to the electronic mail and needs to be formed into a predetermined format, such as data indicating the execution state of the script.

[0353] In step S525, the data forming unit 517 shapes the data supplied from the script interpreter 506 into a predetermined format. Data configuration unit 517
Supplies the molded data to the encoder 518 via the interface 504.

[0354] In step S526, the script interpreter 506 supplies a script or data to be attached to the electronic mail to the encoder 518 via the interface 504. The data that the script interpreter 506 directly supplies to the encoder 518 is data that does not need to be formed in the data configuration unit 517.

[0355] In step S527, the encoder 5
Reference numeral 18 encodes the data supplied from the data configuration unit 517 or the data supplied from the script interpreter 506 by, for example, a method such as Base64. The encoder 518 supplies the encoded data and the script to the mail generation unit 519.

In step S528, mail generating section 519 generates mail 151 with the script or data attached, based on the script or data supplied from encoder 518. The mail generation unit 519 includes the mail transmission / reception program plug-in interface 50
1, the generated mail 151 is supplied to the mail transmission / reception program 104.

In step S529, mail transmission / reception program 104 transmits mail 151 supplied from mail generation section 519, and the process ends.

If it is determined in step S511 that input / output, storage or reading of information, or access to an external application program is not requested, input / output, storage or reading of information, or access to an external application program is determined. Since the processing of step S512 is unnecessary, the processing of steps S512 to S522 is skipped, and the procedure proceeds to step S523 to determine whether or not to transmit the execution result of the script by e-mail.

If it is determined in step S523 that the script execution result is not to be transmitted by e-mail,
Since there is no need to send an e-mail, step S5
Steps S24 to S529 are skipped, and the process ends.

As described above, the interpreter 106 shown in FIG. 30 can extract the script attached to the mail 151 and execute it when trying to display the mail 151 to which the script is attached.

The interpreter 106 whose structure is shown in FIG.
When input / output, storage or reading of information, or access to an external application program is requested by execution of a script attached to the mail 151, the requested input / output, storage or reading of information, or external Of the application program can be executed.

In addition, interpreter 1 whose configuration is shown in FIG.
06, when transmission of the execution result of the script by e-mail is requested, an e-mail 151 attached with the script or data can be transmitted according to the execution result of the script.

Next, a process of executing a script stored in the script database 521 by the interpreter 106 having the configuration shown in FIG. 30 will be described with reference to flowcharts shown in FIGS.

[0364] In step S601, the script launcher 520 stores the script database 521 based on the input from the touch pad, for example,
One script is selected from a script such as the Othello game script 531, the scheduled mail script 532, the ToDo mail script 533, or the business card mail script 534, and the selected script is supplied to the syntax analysis unit 505 via the interface 504. .

Steps S 602 to S 624 correspond to steps S 507 to S 5, respectively.
Since the processing is the same as each of the 29 processings, the description thereof is omitted.

As described above, the interpreter 106 shown in FIG. 30 can execute the selected and stored script.

The interpreter 106 whose structure is shown in FIG.
When the selected, stored script is executed, input / output, storage or reading of information, or when access to an external application program is requested, the requested input / output, storage or reading of information, Alternatively, access to an external application program can be performed.

The interpreter 1 whose configuration is shown in FIG.
06 is a mail 15 attached with a script or data by executing the selected and stored script.
1 can be sent.

Next, the processing of executing the script attached to the e-mail described with reference to the flowcharts of FIGS. 35 to 37 and the processing of executing the script described with reference to the flowcharts of FIGS. 38 to 40 will be described. A specific example of the processing will be described.

For example, the PDA 1, personal computer 3, or e-mail transmitted by the camera-equipped digital mobile phone 301 to which e-mail with a script can be transmitted include the PDA 1, personal computer 3, or camera of the e-mail recipient. An application program that registers the subject of work and the deadline date of the digital mobile phone 301 (for example,
A script for adding information on a job requested by the sender of the mail can be attached to a list (for example, a ToDo list) recorded by the processing of the ToDo book program 515 in FIG. Here, the mail to which such a script is attached is called a ToDo mail.

At step S601 in FIG. 38, the script launcher 520
1, the ToDo mail script 533 is read, and the processing of steps S602 to S605 is executed. In step S605, the ToDo mail script 533 is read.
Is determined to be valid, a ToDo mail creation screen shown in FIG. 41 is displayed. On the ToDo mail creation screen, the destination of the mail, the destination of carbon copy (CC), items,
Deadlines and comments can be entered by the user.

In order for the user to display the ToDo mail creation screen, for example, on the initial display screen shown in FIG. 32, the user taps the icon described as ToDo mail, and similarly, the initial display screen shown in FIG. On the screen
By tapping the icon described as ToDo, the ToDo book program 515 is started, and as shown in FIG. 42, the "Create ToDo mail" item is selected from the menu 621 on the execution screen of the ToDo book program 515. 32, or by tapping the icon described as “mail” on the initial display screen shown in FIG. 32, the mail transmission / reception program 104 is activated, and FIG.
As shown in FIG. 3, the "Create ToDo Mail" item may be selected from the menu 631 on the execution screen of the mail transmission / reception program 104.

Next, referring to the flowchart of FIG. 44, steps S605 of FIG. 38 to step S605 of FIG.
As a specific example of the process 617, a process of creating a ToDo mail to which the present invention is applied will be described. Here, Palm OS
The following description assumes that a ToDo mail is created by the PDA 1 equipped with a todo mail. For example, when a ToDo mail is created in the personal computer 3, the digital mobile phone with camera 301, etc., basically the same processing is executed. Is done.

A user who wants to send a ToDo mail is shown in FIG.
Since the above-described operation is executed to display the ToDo mail creation screen described with reference to the above, the script interpreter 506 transmits the I / O module 510, the platform resource access interface 509, and the resource access manager 508 in step S641. In accordance with a signal input from the touchpad control unit 38 or the jog dial 23 via the touchpad control unit 38, a control signal for displaying the ToDo mail creation screen on the display unit 21 is generated and output to the resource access manager 508. The resource access manager 508 causes the I / O module 510 to display a ToDo mail creation screen on the display unit 21.

The user refers to the ToDo mail creation screen shown in FIG. 41 and fills in blanks with necessary information. In step S642, the script interpreter 506
From the touchpad control unit 38 via the I / O module 510, the platform resource access interface 509, and the resource access manager 508, the destination (including the CC), the subject, the item, the deadline, and the comment Receive input.

In step S643, the script interpreter 506 reads the script attached to the ToDo mail to be transmitted, and outputs the read script to the mail generator 519 via the interface 504 and the encoder 518 together with the input data. The script read here is the running ToDo mail script 533
May be included, or may be recorded in the script database 521.

In step S644, mail generation section 519 generates mail 151 described with reference to FIG. 12 by attaching the script and the input data to the mail.

In step S645, the mail generation unit 519 determines a process ID that is a unique number for each ToDo mail, and associates the process ID with the mail 151 created in step S644, and executes the processing in FIG.
Proceeding to S618, the ToDo mail is transmitted by the subsequent processing.

By the process described with reference to FIG. 44, a ToDo mail to which a script for adding a new item is added to the ToDo list of the mail recipient is created.

Next, with reference to the flowchart of FIG. 45, the PDA 1 that has received the ToDo mail created by the processing described with reference to the flowchart of FIG.
A script execution process will be described as a specific example of the process executed in steps S510 to S529 of FIG.

In step S671, the script interpreter 506 executes the show () method of the script extracted in step S503 in FIG.
A control signal for displaying the body of the received mail is generated and output to the resource access manager 508. The resource access manager 508 displays the text of the received mail on the display unit 21 on the I / O module 510.

FIG. 46 shows an example of the displayed mail. This e-mail contains the subject, item, deadline, and comment set in step S642 in FIG.

[0383] In step S672, the script interpreter 506 generates a control signal for displaying a dialog box for confirming that the script is to be entered into the schedule, and outputs the control signal to the resource access manager 508. The resource access manager 508 causes the I / O module 510 to display a dialog box on the display unit 21.

FIG. 47 shows an example of the dialog box 641 displayed. The dialog box 641 displays a YES button 642 selected when adding items and deadlines specified by e-mail to the ToDo list, and a NO button 643 selected when not adding to the ToDo list. For example, when the recipient cannot refuse the item such as the job specified by the mail and the item is forcibly set, the NO button 643 may not be displayed.

[0385] In step S673, the script interpreter 506 sends the I / O module 510, platform resource access interface 509,
Then, it is determined whether or not YES button 642 is selected based on a signal indicating a user operation input from jog dial 23 or touch pad control unit 38 via resource access manager 508.

If it is determined in step S673 that YES button 652 has been selected, step S67
In 4, the script interpreter 506 generates a control signal for generating a reply mail for notifying acceptance of the job requested by the mail, and outputs the control signal to the mail generation unit 519 via the interface 504 and the encoder 518. . The mail generation unit 519 generates a mail in which a message indicating that the requested work is approved is described, and includes a factor (for example, 0) indicating that the requested work is approved and the process ID as data,
Mail sending / receiving program plug-in interface 5
01 to the mail sending / receiving program 104.

At step S675, mail transmission / reception program 104 returns the reply mail created at step S674. In step S676, the script interpreter 506 causes the resource access manager 508 to access the ToDo list recorded by the processing of the ToDo book program 515 via the storage module 511, and the items included in the received mail and the deadline To update the to-do list.

If it is determined in step S673 that YES button 642 has not been selected, in step S677, script interpreter 506 executes
A control signal for generating a reply mail for rejecting the job requested by the mail is generated, and the interface 50
4 and the mail generation unit 51 via the encoder 518.
9 is output. The mail generation unit 519 generates a mail in which a message indicating that the requested task cannot be performed is described, generates a factor (for example, 1) indicating that the requested task cannot be performed, and a process ID as data, and transmits and receives the mail. Output to the mail transmission / reception program 104 via the program plug-in interface 501. In step S678, the mail transmission / reception program 10
No. 4 returns the reply mail created in step S677.

Step S676 or step S67
8, the script interpreter 506 generates a control signal for displaying a dialog box indicating the end of the process and outputs the control signal to the resource access manager 508 in step S679. The resource access manager 508 controls the I / O module 510
Then, a dialog box is displayed on the display unit 21 and the process is terminated.

FIG. 48 shows a display example of a dialog box 651 indicating the end of the processing. The job requested by email has been accepted (YES button 642 was selected)
In this case, as shown in FIG. 48, for example, a dialog box 651 in which a message “Reply to Ms. Ando (ToDo mail sender) and put it in the ToDo list” is displayed is displayed. As shown in FIG. 49, for example, as shown in FIG. 49, a mail indicating the item and the deadline is returned to the sender of the ToDo mail, together with the comment "I have accepted the following."

If the job requested by e-mail is accepted (YES button 642 is selected),
To recorded by the processing of the ToDo book program 515
A new item is added to the Do list. The to-do list is
For example, the icon can be displayed by tapping the icon described as ToDo on the initial display screen shown in FIG. 32 and activating the ToDo book program 515. FIG. 50 shows a display example of a ToDo list to which a new item has been added by the processing described using the flowchart of FIG.

On the other hand, if the job requested by the e-mail cannot be performed (the NO button 643 is selected), for example, the message “May not be able to accept the item (Mr. Ando)
Dialog box with the message `` Reply to Do mail sender) '' is displayed, and the sender of the ToDo mail will be notified, for example, with the comment, `` Sorry, we cannot accept the following. '' An email with the deadline is sent back.

In the case where the importance of the job is ranked and the importance of the item or the like is high, or when the email is a ToDo email transmitted from a predetermined sender (for example, a boss or a business partner), To prevent the recipient from refusing to add the corresponding item to the ToDo list, for example, the dialog box 641 described with reference to FIG.
May not be displayed (that is, the receiver can only select the YES button 642).

[0394] Also, here, it is described that mail including a script is transmitted and received via the Internet 4. For example, communication using radio waves or electromagnetic waves, infrared communication, wireless communication such as Buletooth, It goes without saying that the same processing can be executed in any case of using any communication method such as wired communication via a predetermined cable.

The above-described series of processing can be executed by hardware, but can also be executed by software. When a series of processing is executed by software, a program constituting the software can execute various functions by installing a computer built into dedicated hardware or installing various programs. It is installed from a recording medium into a possible general-purpose personal computer or the like.
