And then, when performing transmission operation of the e-mail, the electronic mail terminal device retrieves a destination address AD or an extraction connection domain name extracted from the destination address AD within the address information database DB1, and displays the address image PA in association with the longest selection address ADS together with a character string of the destination address AD in a destination column C14 of a destination confirmation screen SC. Thereby the electronic mail terminal device 1 can remarkably improve its identifiability by displaying the address image PA in association with the destination address AD together with the character string immediately before transmitting the e-mail.

Description

  The present invention relates to a destination display device, a destination display method, and a destination display program, and is suitable for application to an e-mail terminal device that performs e-mail transmission processing, for example.

  In recent years, electronic mail has become widespread as a communication means, and in addition to computer devices, it can be used by various electronic devices such as communication terminals such as mobile phones, television devices, game devices, and navigation devices. Yes.

  In these devices that can send and receive e-mails (hereinafter collectively referred to as e-mail terminal devices), when sending e-mails, an e-mail address that represents a destination (hereinafter referred to as a destination address) by a user operation or the like. To specify). Specifically, the user is selected from the address book or directly input.

  If the destination address is erroneously set due to erroneous selection or input, the electronic mail is erroneously transmitted to an unintended partner. In particular, if important information is mistakenly transmitted, it will lead to a serious problem such as confidential leakage.

  As described above, it is necessary for the user to set the e-mail destination address accurately. Thus, some e-mail terminals have been proposed in which an address confirmation screen is displayed before the e-mail is transmitted to prompt the user to confirm (see, for example, Patent Document 1).

JP 2010-130515 A (FIG. 3)

  By the way, e-mail addresses are connected by connecting multiple domain names consisting of character strings via “.” And various users via “@” to specify unique addresses on the network by various servers that perform forwarding processing. It has a structure that concatenates names.

  Such an e-mail address is easy to identify for various servers and the like, but is not always easy for a user to recognize, and thus may be erroneously recognized by the user. In general, since user names and domain names are composed of English character strings, the possibility of erroneous input or recognition is increased particularly for users who are not familiar with English characters.

  For this reason, even if the confirmation screen is displayed as in Patent Document 1, as long as the e-mail address is displayed as a character string, there is still a possibility of being misread or misrecognized. The possibility of doing so could not always be excluded.

  The present invention has been made in consideration of the above points, and intends to propose a destination display device, a destination display method, and a destination display program capable of significantly increasing the identification of addresses.

  In order to solve such a problem, in the present invention, a tree structure is hierarchized so as to constitute a tree structure, and a domain structure is assigned to each tree structure from a predetermined target organization to a top-level organization. An address including a concatenated domain name obtained by sequentially concatenating each domain name of each organization that sequentially passes through a predetermined concatenation symbol is acquired by a predetermined acquiring unit as a destination address, and a concatenated domain name from the destination address is acquired by a predetermined extracting unit The linked domain name is generated by extracting a part constituting the domain name, and the linked domain name is stored in a storage unit that stores the linked domain name and the image representing the domain in association with each other by a predetermined search unit. A domain name that matches the extracted linked domain name is searched for as a registered linked domain name, and the registered domain name is registered by a predetermined display processing unit. Reading an image in association with the name stored from the storage unit, and so as to be displayed on a predetermined display unit in association with the destination address.

  As a result, in the present invention, an image corresponding to the linked domain name that can be extracted from the destination address can be displayed together with the destination address, so that the organization corresponding to the image can be recalled to correctly identify the address. .

  According to the present invention, an image corresponding to a linked domain name that can be extracted from the destination address can be displayed together with the destination address, so that the address can be correctly identified by recalling the organization corresponding to the image. . Thus, the present invention can realize a destination display device, a destination display method, and a destination display program that can remarkably improve the discriminating ability of an address.

  Hereinafter, modes for carrying out the invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

[1. First Embodiment]
[1-1. Configuration of e-mail terminal device]
In FIG. 1, an e-mail terminal apparatus 1 is configured to perform e-mail transmission / reception processing in accordance with user operation instructions.

  The electronic mail terminal device 1 includes a control unit 11 that performs overall control, a storage unit 12 that stores various types of information, an operation unit 13 that receives user operations, and a display unit that displays various types of information, as with a general computer device. 14 and a communication unit 15 that performs communication processing with the outside are connected to each other via a bus 16.

  The control unit 11 is configured around a CPU (Central Processing Unit) (not shown), and uses a RAM (Random Access Memory) (not shown) as a work area while reading from the storage unit 12 or a ROM (Read Only Memory) (not shown). Various programs are executed.

  The storage unit 12 is configured by, for example, a hard disk drive or the like, stores various programs such as an e-mail transmission / reception program, various information, and the like, and reads and supplies the information in response to a request from the control unit 11. ing.

  The operation unit 13 is composed of, for example, a keyboard, a track pad, etc., and receives an input instruction from the user and supplies it to the control unit 11.

  The display unit 14 is composed of a liquid crystal panel, for example, and displays various display screens according to display control of the control unit 21 to present the contents to a maintenance worker.

  The communication unit 15 is a network interface conforming to a standard such as IEEE (Institute of Electrical and Electronics Engineers) 802.3ab, and is connected to various network devices and various servers via the Internet 5 according to the communication control of the control unit 11. Communication processing is performed between the two.

[1-2. Email address configuration]
Next, the configuration of the e-mail address will be described. The Internet 5 has a configuration in which a plurality of domains each managing a certain number of e-mail terminal devices and server devices are combined in order to efficiently manage an extremely large number of e-mail terminal devices and server devices. Yes.

  These domains are hierarchized to form a tree structure as shown in FIG. Each domain represents an organization on the Internet, and an account is assigned to a user belonging to the organization. That is, the e-mail account belongs to one of the domains.

  Correspondingly, as shown in FIG. 3 (A), the e-mail address is generally expressed as a character string in which a plurality of characters and symbols are combined, and the first half account name portion N1 and the second half domain. The portion N2 is connected by the connection symbol “@”.

  The domain part N2 in the latter half has a structure in which domain names DN4 to DN1 of domains through which the tree structure in FIG. 2 is sequentially traced from a certain domain to the highest domain are sequentially linked by a concatenation symbol “.”. Uniquely represents the domain to which the account belongs.

  Hereinafter, the domain name of each domain that passes through the tree structure of FIG. 2 from an arbitrary domain to the highest domain in this way is sequentially linked by a linking symbol “.” Is called a linked domain name.

  That is, as shown in FIGS. 3B to 3E, the domain names DN4 to DN1 are linked to represent the entire domain part N2 of the e-mail address as shown in FIG. 2 includes only domain names DN3 to DN1, DN2 to DN1, or DN1 in the tree structure of FIG.

  The first half of the account name portion N1 is assigned a unique name in the domain represented by the second half of the domain portion N2.

  In this way, the e-mail address is obtained by concatenating a plurality of domain names in accordance with the tree structure (FIG. 2) of each domain in the Internet 5 in the latter domain portion N2, so that the domain (ie, organization) of the account belongs to. It is designed to represent the structure.

[1-3. Address Information Database Configuration]
By the way, in addition to the various programs described above, the storage unit 12 of the electronic mail terminal device 1 stores an address information database DB1 as shown in FIG.

  The address information database DB1 stores a plurality of address information F1 representing linked domain names or e-mail addresses, and image information F2, risk information F3, and type information F4 are associated with the address information F1, respectively. ing.

  In general, some linked domain names are assigned to companies, organizations, or providers such as providers in the real world. That is, the linked domain name of the address information F1 can be regarded as information that substantially represents these organizations.

  Some organizations such as a company organization and a group have a mark, a logo, or the like representing the organization from the viewpoint of enhancing the identification power of the organization. Therefore, in the image information F2, an image such as a mark or a logo representing an organization to which the linked domain name of the address information F1 is assigned (hereinafter referred to as a domain image PD) is registered.

  Further, as the address information F1, an e-mail address in which an account is linked to a linked domain name via a linked symbol “@” can be registered. In this case, as the image information F2, it is possible to register an image made up of a personal face image to which the account is assigned (hereinafter referred to as a personal image PP). For convenience of explanation, the domain image PD and the personal image PP are collectively referred to as an address image PA below.

  By the way, among the organizations to which the linked domain name of the address information F1 is assigned, there are providers that provide accounts freely for free. Among those who use such providers, there are those who abuse the e-mail address and the contents of the e-mail. Therefore, care must be taken when sending e-mail to such provider's account.

  On the other hand, for example, when the user of the electronic mail terminal device 1 is an employee of a corporation and has an account of a linked domain name assigned to the corporation, the linked domain name representing the same company is It is considered safer than other companies and organizations.

  Therefore, the risk level (risk level) for the organization to which the linked domain name is assigned can be registered in the risk level information F3 with respect to the address information F1. As the risk level information F3, “low” indicating that it is relatively safe, “high” that is relatively dangerous, or “normal” that is intermediate between them is registered.

  In addition, there are various types of organizations, such as countries, corporations, schools, and providers, to which the linked domain name of the address information F1 is assigned. Therefore, the type of the organization can be set in the type information F4.

  As described above, in the address information database DB1, the image information F2, the risk information F3, and the type information representing the address image PA (domain image PD or personal image PP) with respect to the address information F1 including the linked domain name or the e-mail address. F4 is registered in association with each other.

[1-4. Email sending process]
When the control unit 11 of the e-mail terminal device 1 receives an instruction to start the e-mail transmission / reception program by a user operation, the control unit 11 reads the e-mail transmission / reception program from the storage unit 12 and executes it.

  This e-mail transmission / reception program has a general function related to e-mail, e-mail transmission processing for newly creating and sending e-mail, and receiving e-mail sent to a user account An e-mail receiving process for displaying the contents can be performed.

  The e-mail transmission / reception program can also perform distribution processing for distributing received e-mails to various folders, address management processing for registering e-mail addresses in the address book, updating / deleting, and the like.

  For example, when receiving an e-mail creation instruction on the e-mail transmission / reception program by a user operation, the control unit 11 causes the display unit 14 to display an e-mail creation screen SN as shown in FIG.

  The e-mail creation screen SN includes a title column C1 for allowing a user to input a title, a text column C2 for inputting an e-mail text, a destination column C3 for inputting a destination address of the e-mail, and CC (Carbon Copy) and BCC ( A CC column C4 and a BCC column C5 are provided for inputting destination addresses of (Blind Carbon Copy).

  Further, the e-mail creation screen SN is provided with an address book button B1 for selecting a destination address, CC and BCC destination addresses from the address book, and a send button B2 for sending the e-mail after it is created. It has been.

  When the transmission button B2 is pressed in a state where necessary items are entered in the title column C1, the body column C2, and the destination column C3 on the e-mail creation screen SN, the control unit 11, as shown in FIG. A destination confirmation screen SC for allowing the user to confirm the destination address is displayed on the display unit 14 as a subwindow.

  The destination confirmation screen SC includes a title column C11, a sender column C12, a reply destination column C13, a destination column C14, a CC column C15, a BCC column C16, and a file column C17. The destination confirmation screen D2 is also provided with an “OK” button B11 for executing transmission of an electronic mail and a “cancel” button B12 for canceling transmission of the electronic mail.

  In the destination column C14, the destination address AD input in the destination column C3 of the e-mail creation screen SN is displayed as a character string, and the address image PA corresponding to the destination address AD is addressed for each destination address AD. It is read from the information database DB1 and displayed.

  At this time, the control unit 11 selects and displays the most appropriate one to be displayed in association with the destination address AD among the address images PA registered in the address information database DB1 (details). Will be described later).

  When the contents such as the destination address AD displayed on the destination confirmation screen SC are determined to be correct by the user, the “OK” button B11 is clicked by the operation of the user. In response to this, the control unit 11 transmits the electronic mail.

  On the other hand, when it is determined by the user that there is an error in the contents such as the destination address AD displayed on the destination confirmation screen SC, the “cancel” button B12 is clicked by the user's operation. In response to this, the control unit 11 deletes the destination confirmation screen SC, displays the e-mail creation screen SN again, and causes the user to make appropriate corrections.

  In this way, the control unit 11 presents the character string and the address image PA highly relevant to the destination address AD on the destination confirmation screen SC to the user, so that there is a risk of misreading or misrecognition by the user. Is greatly reduced, and an appropriate confirmation operation can be performed.

[1-5. Address confirmation screen display process]
Next, display processing of the destination confirmation screen SC (FIG. 6) will be described.

  When the send button B2 is pressed on the e-mail creation screen SN (FIG. 5), the control unit 11 reads and executes the destination confirmation screen display program from the storage unit 12 (FIG. 1). As a result, the control unit 11 configures functional blocks of a destination address acquisition unit 21, an extraction unit 22, a search unit 23, a selection unit 24, and a display processing unit 25 therein as shown in FIG.

  The destination address acquisition unit 21 acquires the destination address AD input in the destination column C3 of the e-mail creation screen SN, and supplies this to the extraction unit 22.

  Based on the supplied destination address AD (FIG. 3A), the extraction unit 22 extracts the extracted linked domain name DC4 (FIG. 3) obtained by removing the first half of the account name portion N1 and the concatenation symbol “@” from the destination address AD. (B)) is extracted.

  The extraction unit 22 also extracts the extracted linked domain name DC3 (FIG. 3 (C)) from which the lowest domain name (for example, the domain name DN4) included in the extracted linked domain name DC4 and the immediately following link symbol “.” Are removed. And the extracted linked domain names DC2 and DC1 (FIGS. 3D and 3E) are sequentially extracted by repeating the same process.

  Hereinafter, the process of extracting a plurality of extracted linked domain names DC4 to DC1 based on the destination address name AD will be referred to as an extraction process. Hereinafter, for convenience of explanation, the destination address AD and the extracted linked domain names DC4 to DC1 are collectively referred to as an extracted address ADE. The extraction unit 22 supplies the extraction address ADE to the search unit 23.

  Incidentally, the number of domain names constituting the destination address AD is not constant, and generally about 2 to 5 domain names are connected. For this reason, the number of extraction addresses ADE differs depending on the number of domain names included.

  The search unit 23 searches the address information database DB1 of the storage unit 12 to select one of the extracted addresses ADE registered in the address information F1 of the address information database DB1, and extracts these from the registered extracted address ADR. To the selection unit 24.

  Incidentally, if no extracted address ADE is registered in the address information database DB1, the search unit 23 notifies the selection unit 24 to that effect.

  Here, focusing on the extracted linked domain names DC4 and DC3, the organization represented by the extracted linked domain name DC3 belongs to the lower level of the organization represented by the extracted linked domain name DC4 (FIG. 2). On the other hand, it can be said that the destination address AD representing the personal account itself represents in more detail than the extracted linked domain name DC4 that merely represents the organization in that the account name is included.

  For this reason, it can be said that the destination address AD in the extracted address ADE in the most detail is the longest destination address name AD, and the number of domain names included such as the extracted linked domain names DC4, DC3,. As the number decreases, the destination becomes coarser in stages.

  Therefore, the selection unit 24 selects the longest registered extracted address ADR, that is, the extracted concatenated domain name DC including the destination address name AD or the most domain names, and uses this as the selection address ADS as the display processing unit. 25.

  Incidentally, when no extracted address ADE is registered in the address information database DB1, the selection unit 24 notifies the display processing unit 25 to that effect.

  The display processing unit 25 displays the destination confirmation screen SC (FIG. 6) on the display unit 14 (FIG. 2). At this time, the display processing unit 25 displays the address image PA of the image information F2 registered in association with the selected address ADS in the address information database DB1 so as to be adjacent to the character string of the destination address AD in the destination column C14. .

  Further, the display processing unit 25 determines the portion corresponding to the selected address ADS among the characters of the destination address AD according to the risk information F3 registered in the address information database DB1 in association with the selected address ADS. Change the text color.

  At this time, for example, when the risk is “low”, the display processing unit 25 sets the character color to green (shown in bold in the figure), and when the risk is “normal”, the display color is yellow. When the degree of danger is “high”, the character color is red (indicated by white characters in the figure).

  On the other hand, if no extracted address ADE is registered in the address information database DB1, the display processing unit 25 displays the destination address AD with only the characters in the normal display color.

  Thus, the control unit 11 extracts the extracted address ADE from the destination address AD, reads the address image PA registered in association with the extracted address ADE from the address information database DB1, and displays the address confirmation screen SC together with the destination address AD. It is displayed in the destination column C14.

[1-6. Address confirmation screen display processing procedure]
Next, the display processing procedure of the destination confirmation screen SC (FIG. 6) will be described using the flowchart of FIG.

  When the send button B2 is pressed on the e-mail creation screen SN (FIG. 5) and the destination confirmation screen display program is started, the control unit 11 starts the destination confirmation screen display processing procedure RT1 and proceeds to step SP1. In step SP1, the control unit 11 acquires the destination address AD by the destination address acquisition unit 21 (FIG. 7), and proceeds to the next step SP2.

  In step SP2, the control unit 11 extracts the extracted linked domain names DC4 to DC1 from the destination address AD by the extraction unit 22 (FIG. 7), and proceeds to the next step SP3.

  In step SP3, the control unit 11 searches the address information database DB1 in the storage unit 12 by the search unit 23, selects registered ones of the extracted addresses ADE, and uses these as registered extracted addresses ADR for the next. Control goes to step SP4.

  In step SP4, the control unit 11 determines whether any one of the extracted addresses ADE is registered in the address information database DB1 by the selection unit 24. If a positive result is obtained here, this indicates that there is an address image PA to be displayed in the destination column C14 of the destination confirmation screen SC, and at this time, the control unit 11 moves to the next step SP5.

  In step SP5, the control unit 11 uses the selection unit 24 to select the longest registered extraction address ADR, and uses this as the selection address ADS to proceed to the next step SP6.

  In step SP6, the control unit 11 uses the display processing unit 25 to place the address image PA registered in the address information database DB1 in association with the selected address ADS in the destination column C14, adjacent to the character of the destination address AD. The destination confirmation screen SC is displayed on the display unit 14.

  At this time, the control unit 11 causes the display processing unit 25 to change the character color of the portion corresponding to the selected address ADS among the characters of the destination address AD to a color corresponding to the risk information F3 registered in the address information database DB1. Change to the next step SP8.

  On the other hand, if a negative result is obtained in step SP4, this indicates that there is no address image PA to be displayed in the destination column C14 of the destination confirmation screen SC, and at this time, the control unit 11 proceeds to the next step SP7. .

  In step SP7, the control unit 11 causes the display processing unit 25 to display a destination confirmation screen SC in which the destination address AD is displayed only in characters in the destination column C14 on the display unit 14, and proceeds to the next step SP8.

  In step SP8, the control unit 11 determines whether or not the “OK” button B11 is pressed. If an affirmative result is obtained here, this means that the user has visually confirmed that there is no error in the contents of the destination confirmation screen SC. At this time, the control unit 11 proceeds to the next step SP9.

  In step SP9, the control unit 11 performs transmission processing for transmitting the e-mail being created, erases the destination confirmation screen SC, moves to next step SP12, and ends the destination confirmation screen display processing procedure RT1.

  On the other hand, if a negative result is obtained in step SP8, the control unit 11 proceeds to the next step SP10 and determines whether or not the “cancel” button B12 is pressed.

  If a negative result is obtained here, this means that neither the “OK” button B11 nor the “Cancel” button B12 has been pressed yet, and the contents of the destination confirmation screen SC may be being confirmed. Is high. At this time, the control unit 11 returns to step SP8 again and waits for either the “OK” button B11 or the “cancel” button B12 to be pressed.

  On the other hand, if a positive result is obtained in step SP10, this indicates that the user has visually confirmed that there is an error in the contents of the destination confirmation screen SC. At this time, the control unit 11 proceeds to the next step SP11. Move.

  In step SP11, the control unit 11 corrects the content displayed on the destination confirmation screen SC, that is, the information about the destination address AD of the email, and the original email creation screen SN after deleting the destination confirmation screen SC. After returning to (FIG. 5), the process proceeds to step SP12 and the destination confirmation screen display processing procedure RT1 is terminated.

[1-7. Operation and effect]
In the above configuration, the control unit 11 of the electronic mail terminal device 1 stores the image information F2 in the address information database DB1 in advance in association with the image information F2 for each address information F1 in the storage unit 12.

  Thereafter, the control unit 11 executes the e-mail transmission / reception program according to the user's operation, and further receives an e-mail creation instruction, displays the e-mail creation screen SN (FIG. 5), displays the title column C1, the body column C2, and the destination. Input necessary information in column C3 and the like.

  When the send button B2 on the e-mail creation screen SN is pressed, the control unit 11 acquires the destination address AD in the destination column C3, generates the extracted linked domain names DC4 to DC1, and extracts the extracted address ADE together with the destination address AD. To do.

  Subsequently, the control unit 11 searches the address information database DB1 for the extracted address ADE and sets it as the registered extracted address ADR. The longest one is selected as the selected address ADS, and the address image PA associated with the selected address ADS is selected. Along with the character string of the destination address AD, it is displayed in the destination column C14 of the destination confirmation screen SC.

  Thereby, the e-mail terminal device 1 displays the address image PA corresponding to the destination address AD or the domain name included in the destination address AD together with the character string of the destination address AD immediately before sending the e-mail. Can do. For this reason, the e-mail terminal device 1 can dramatically increase its discriminating power as compared with the case where the destination address AD is displayed only by characters.

  In general, inside an information processing apparatus such as the electronic mail terminal device 1 or a mail server, characters constituting an electronic mail address are handled by a character code or the like. For this reason, if the character code of each character representing each of the two destination addresses is binarized, even if there is a difference in even one bit, the information processing apparatus can handle the two as completely different .

  On the other hand, a user (that is, a human) recognizes a character through vision. For this reason, if the appearances of the characters constituting the two destination addresses are similar, the user may misrecognize or confuse them.

  However, in general, in the case of an image, for example, even two types of logo marks each of which is similar to each other are designed visually depending on the design method, the font type and size of the characters, colors, combined figures, etc. Can be completely different. Especially in the real world, there are cases where logos and the like are greatly different from the viewpoint of preventing confusion even among organizations with similar names. These logo marks are recognized as representing organizations in the real world.

  For these reasons, there is no need to remind the user of the relevance of displaying the person belonging to the organization in association with the logo mark or the like on the address confirmation screen SC. The organization can be recalled based on the image PD, and the correctness / incorrectness of the corresponding linked domain name can be easily recognized.

  The displayed domain image PD represents an organization to which a linked domain name is assigned, such as a company logo mark or a national flag, and is generally an image having high discrimination power. For this reason, the e-mail terminal device 1 can significantly reduce the possibility of being erroneously recognized by the user as compared with the case where only the character string that needs to check the destination address AD character by character is displayed.

  Further, these domain images PD are associated with a destination address AD or a linked domain name. For this reason, for example, one domain image PD representing the entire organization is prepared and only one is registered in the address information database DB1 without the trouble of preparing and registering individual face images one by one.

  For example, it is assumed that Mr. Sato (sato@mm.co.jp) of MM Corporation and Mr. Sato (sato@nn.co.jp) of NN Corporation are registered in the address book. In this case, since the account names are the same and the linked domain names are similar in appearance, there is a high possibility that the user will misrecognize either one as the other when only the characters are displayed.

  However, even in this case, if a domain image PD consisting of each company's logo, etc. is registered for each linked domain name, the company's logo mark, etc. generally has high discrimination power. Due to the difference in images, it is possible to reduce the possibility of being erroneously recognized by the user.

  In addition, Mr. Saito (saito@mm.co.jp) of MM Co., Ltd. is also registered in the address book, and the e-mail destination address that the user should send to Mr. Saito is mistaken for the NN company Sato (sato @ nn.co.jp). In this case, the electronic mail terminal device 1 can easily recognize that at least the company name is different from the domain image PD displayed in the destination field C14 of the destination confirmation screen SC.

  On the other hand, it is assumed that the user has mistakenly set the e-mail destination address to be sent to Mr. Saito to Mr. Sato (sato@nn.co.jp) of the MM company (that is, the same company). In this case, since the domain image PD displayed in the destination column C14 of the destination confirmation screen SC by the electronic mail terminal device 1 is a logo mark of MM, etc., it is recognized that the destination address is incorrect depending on the image. I can't.

  However, in this case, since at least the linked domain name (that is, the organization to which it belongs) can be recognized by the domain image PD, it is possible to prevent the occurrence of a serious problem such as erroneous notification of confidential matters to other companies. be able to.

  Further, when the e-mail address is registered in the address information database DB1, the e-mail terminal apparatus 1 displays the personal image PP (for example, a face image) registered in association with the e-mail address on the destination confirmation screen SC. It can be displayed in the destination column C14. Thereby, the discriminating power of account names similar to each other belonging to the same domain can be enhanced.

  Further, the e-mail terminal device 1 changes the portion corresponding to the selected address ADS in the character string constituting the destination address AD in the destination column C14 of the destination confirmation screen SC to a display color corresponding to the risk information F3. For this reason, the e-mail terminal device 1 can also call attention to confirming again that confidential information was not included because it is a dangerous destination due to the difference in display color.

  According to the above configuration, the electronic mail terminal device 1 registers the linked domain name or the electronic mail address and the address image PA in advance in the address information database DB1. Then, the electronic mail terminal device 1 searches the address information database DB1 for the destination address AD or the extracted concatenated domain name extracted from the destination address AD, and associates it with the longest selected address ADS. The address image PA being displayed is displayed in the destination field C14 of the destination confirmation screen SC together with the character string of the destination address AD. Thus, the e-mail terminal device 1 can dramatically increase its discriminating power by displaying the address image PA corresponding to the destination address AD together with the character string immediately before sending the e-mail.

[2. Second Embodiment]
[2-1. Configuration of e-mail system]

  In step SP23, when the URL included in the URL notification mail is clicked by the user, the control unit 51 reads and executes the web browser program from the storage unit 52, and executes the address indicated by the URL (the e-mail filter device 31). ) To request web data.

  In response to this, the control unit 41 of the e-mail filter device 31 proceeds to step SP33, acquires the e-mail destination address AD associated with the URL accessed by the e-mail filter device 31, and acquires the address information server 37. To notify.

  In response to this, in step SP41, the control unit 61 of the address information server 37 acquires the destination address AD notified from the electronic mail filter device 31 by the destination address acquisition unit 21 (FIG. 11), and proceeds to the next step SP42. .

  In step SP42, similarly to step SP2 (FIG. 8), the control unit 61 extracts the extracted linked domain names DC4 to DC1 from the destination address AD by the extraction unit 22 (FIG. 11), and proceeds to the next step SP43.

  In step SP43, as in step SP3 (FIG. 8), the control unit 61 searches the address information database DB1 in the storage unit 62 by the search unit 23 (FIG. 11), and is registered among the extracted addresses ADE. These are selected as registered extraction addresses ADR and the process proceeds to the next step SP44.

  In step SP44, the control unit 61 uses the selection unit 24 (FIG. 11) to select the longest registered extraction address ADR, and sets this as the selection address ADS.

  Further, the control unit 61 reads various information registered in association with the selected address ADS, that is, the address image PA, the risk information F3, and the type information F4 of the image information F2, and sends the information together with the selected address ADS to the e-mail. Transmit to the filter device 31. Thereafter, the control unit 61 proceeds to step SP45 and ends the routine RT4.

  In response to this, the control unit 41 of the e-mail filter device 31 generates web data representing the destination confirmation screen SC2 by the display processing unit 25 based on the information received from the address information server 37 in step SP34. It is transmitted to the electronic mail terminal device 32.

  In response to this, when the control unit 51 of the e-mail terminal device 32 receives the web data from the e-mail filter device 31, the control unit 51 proceeds to step SP24 and displays a transmission confirmation screen SC2 (FIG. 10) on the display unit 54 by the web browser. To do.

  Subsequently, when the control unit 51 receives a pressing operation of the transmission button B21 on the transmission confirmation screen SC2, the control unit 51 transmits the operation result to the e-mail filter device 31 in step SP25. Thereafter, the control unit 51 proceeds to the next step SP26 and ends the routine RT2.

  Based on the operation result of the send button B21 on the send confirmation screen SC2, the control unit 41 of the e-mail filter device 31 sends a password notification mail to the destination address AD that has a check mark in the selection column C21 on the send confirmation screen SC2. Send. Thereafter, the control unit 41 proceeds to the next step SP36 and ends the routine RT3.

[2-4. Operation and effect]
In the above configuration, in the electronic mail system 30, the image information F2 is associated with the address information database DB1 for each address information F1 and stored in the storage unit 62 of the address information server 37 in advance.

Is transmitted to the e-mail filter device 31.

  The control unit 41 of the e-mail filter device 31 acquires the e-mail, notifies the account of the e-mail terminal device 32 by accessing the URL, and notifies the address information server 37 of the destination address AD of the e-mail.

  When acquiring the destination address AD, the control unit 61 of the address information server 37 generates an extracted linked domain name and sets it as the extracted address ADE together with the destination address AD. Subsequently, the control unit 61 retrieves the extracted address ADE from the address information database DB1 to obtain the registered extracted address ADR. Further, the control unit 61 uses the longest registered extraction address ADR as the selection address ADS, and transmits the address image PA and the like associated with the selection address ADS to the electronic mail filter device 31 together with the selection address ADS. .

  Based on the transmitted address image PA and the selected address ADS, the control unit 41 of the email filter device 31 displays the address image PA together with the character string of the destination address AD in the destination column C14 of the destination confirmation screen SC.

  Thereby, in the electronic mail system 30, the address image PA corresponding to the destination address AD or the domain name included in the destination address AD is transmitted via the web browser of the electronic mail terminal device 32 before the password notification mail is transmitted. It can be displayed on the transmission confirmation screen SC2 together with the character string of the destination address AD.

  For this reason, like the electronic mail terminal device 1 according to the first embodiment, the electronic mail system 30 can dramatically increase its discriminating power as compared with the case where the destination address AD is displayed only by characters. .

  In other respects as well, the electronic mail system 30 can achieve the same operational effects as the electronic mail terminal device 1 according to the first embodiment.

  According to the above configuration, the e-mail system 30 according to the second embodiment registers the linked domain name or e-mail address and the address image PA in advance in the address information database DB1. When the attached file of the e-mail transmitted from the e-mail terminal device 32 is encrypted by the e-mail filter device 31, the address information server 37 extracts the destination address AD or the extracted linked domain name extracted from the destination address AD. A search is made in the information database DB1, and the address image PA associated with the longest selected address ADS is read out. The e-mail filter device 31 displays the address image PA together with the character string of the destination address AD via the web browser of the e-mail terminal device 32 in the destination column C14 of the destination confirmation screen SC, thereby dramatically improving its discrimination power. It can be confirmed in an elevated state.
