The message transmission unit 48 performs processing for transmitting an electronic message to a destination user based on a message transmission request (message request) from a source user. The message request includes the user ID of the source user, the user ID of the destination user, the destination of the message, the electronic message (message text), and the like.

In this embodiment, in the electronic message transmission service, the source user and the destination user exchange electronic messages on a screen common to both users. Specifically, the electronic messaging service in this embodiment provides a text chat service.

FIG. 5 shows an example of a text chat screen displayed on the display unit of the client terminal 12 and provided by the electronic message transmission service. The text chat screen includes a message display area 60 common to a plurality of users included in a chat group (three or more users may be included) including a source user and a destination user. The multiple users included in the chat group may be pre-selected by the source user. Note that any user included in the chat group may be able to add other users to the chat group.

The message display area 60 displays electronic messages sent by each user included in the chat group. As described above, since the message display area 60 is shared by a plurality of users included in the chat group, the electronic message sent by the sender user is also displayed in the message display area 60 of the sender user.

The text chat screen also includes an input field 62 and a send button 64 for the source user to enter an electronic message. When the sender user presses the send button 64 after entering the text of the message in the input field 62 , the client terminal 12 sends a message request to the message sending server 16 . Based on the message request, the message transmission server 16 causes the electronic message to be displayed in the message display area 60 common to a plurality of users included in the chat group, after specifying the sender of the electronic message. In this way, the source user can send electronic messages to other users (ie, destination users) included in the chat group.

As shown in FIG. 5, the electronic message sent by the source user can include a URL, which is link information of content stored in the content management server 14 . A destination user who receives an electronic message containing a content URL can access the content by selecting the URL.

Note that the electronic message transmission service is not limited to text chat, and electronic messages may be transmitted by other methods. For example, the e-mail address of the destination user may be specified in the message request to send the electronic message in e-mail format.

The message processing unit 50 determines whether or not the electronic message received by the message transmission server 16 from the client terminal 12 contains link information of content registered in the content management server 14 (hereinafter referred to as "registered content"). judge. In this embodiment, if the electronic message contains a URL, the message processing unit 50 extracts the URL and transmits it to the content management server 14 . The content management unit 32 of the content management server 14 refers to the content DB 26 (see FIG. 3), determines whether or not the received URL is registered in the content DB 26, and transmits the determination result to the message transmission server 16. . Based on the determination result, the message processing unit 50 determines whether or not the electronic message includes the link information of the registered content.

If the electronic message contains the link information of the registered content, the message processing unit 50 determines whether or not the destination user of the message request has the right to use the registered content. In this embodiment, the message processing unit 50 transmits to the content management server 14 a usage authority confirmation request including the user ID of the destination user included in the received message request and the extracted link information. The content management unit 32 of the content management server 14 refers to the usage authority information in the content DB 26 (FIG. 3), and the user indicated by the user ID included in the usage authority confirmation request is identified by the URL included in the usage authority confirmation request. It is determined whether or not the user has the right to use the registered content (whether or not it can be read). The communication unit 20 of the content management server 14 transmits to the message transmission server 16 the determination result indicating the usage authority of the destination user for the registered content. Thus, the communication unit 20 also functions as a usage authority transmission unit. Based on the determination result, the message processing unit 50 determines whether or not the destination user of the message request has the right to use the registered content.

If the destination user of the message request does not have the right to use the registered content, the message processing unit 50 deletes the link information of the registered content from the electronic message. In this embodiment, the message processing unit 50 deletes the URL of the registered content from the electronic message.

Then, the message transmitting unit 48 transmits the electronic message from which the link information of the registered content is deleted to the destination user. In this embodiment, the message transmitting unit 48 displays the electronic message from which the registered content URL is deleted in the message display area 60 .

FIG. 6 shows a case where the sender user has sent an electronic message including the URL of the registered content shown in the input field 62 of FIG. A display example of the message display area 60 when not having As shown in the message display area 60 of FIG. 6 , the electronic message 70 sent by the source user “Mr. A” has the registered content URL deleted by the message processing unit 50 . As shown in the input field 62 of FIG. 5, the text of the message input by the source user includes the text "Please revise this document" in addition to the URL of the registered content. 48 displays the text in the message display area 60, that is, transmits it to the destination user.

Further, when the URL of the registered content is deleted, the message processing unit 50 may insert a sentence indicating that the URL has been deleted into the electronic message instead of the URL. For example, as shown in the electronic message 70 of FIG. 6, the text "(link information has been deleted)" may be inserted instead of the URL. Furthermore, when the message processing unit 50 deletes the URL of the registered content from the electronic message, the message transmitting unit 48 confirms that the link information is deleted from the electronic message transmitted by the source user as an electronic message from the system. An electronic message may be sent to the destination user indicating that the request has been made. For example, as shown in FIG. 6, the message sending unit 48 sends an electronic message 72 from the system stating that "the link information has been deleted because there was a user who could not access the URL contained in the message." It is displayed on the display area 60 .

As described above, if the destination user of the electronic message does not have the right to use the registered content indicated by the link information included in the electronic message of the source user, the link information is deleted by the message processing unit 50 and Then, the message transmitting unit 48 transmits the electronic message to the destination user. This prevents the link information of the registered content from being sent to the destination user who does not have the right to use the registered content.

In messaging services, a source user can send the same electronic message to multiple destination users. In this embodiment, when three or more users are included in a chat group, an electronic message is sent from a source user to a plurality of destination users.

When the electronic message contains the link information of the registered content, some users among the plurality of destination users do not have the right to use the registered content, and some of the plurality of destination users Consider a case where the remaining users are authorized to use the registered content. In this case, the message transmitting unit 48 transmits the electronic message from which the link information has been deleted by the message processing unit 50 to the destination user who does not have the usage authority of the registered content, and the usage authority of the registered content is granted. , an electronic message that has not been processed by the message processing unit 50, that is, that includes link information of the registered content is transmitted.

In this embodiment, since the message display area 60 is a common screen for users included in the chat group, the URL included in the electronic message sent by the source user may be displayed among the users included in the chat group. If there is even one destination user who does not have the right to use the registered content indicated by , the message sending unit 48 displays the electronic message 70 from which the URL has been deleted in the message display area 60 as in FIG. display. Then, as shown in FIG. 7, an electronic message 82 including the URL is displayed on a separate screen 80 separate from the message display area 60 for the destination user who has the right to use the registered content. The separate screen 80 is a screen that can be viewed only by the user who has the usage authority of the registered content (for example, a screen displayed only on the client terminal 12 used by the user who has the usage authority of the registered content). In this way, the message transmission unit 48 transmits an electronic message including a URL only to users who have the right to use the registered content.

In addition, the message transmission unit 48 transmits the electronic message 82 displayed on the separate screen 80 as an electronic message from the system so that the destination user can easily grasp to which chat group the electronic message 82 was transmitted. , an electronic message 84 indicating to which chat group the electronic message 82 is sent may be displayed on a separate screen 80 .

Returning to FIG. 4, if there is a user among the destination users who does not have the right to use the registered content indicated by the link information included in the electronic message, the notification processing unit 52 , sending a notification to the user from whom the electronic message originated. The notification is for notifying the source user that there is a user among the destination users who does not have the right to use the registered content.

In this embodiment, the notification processing unit 52 transmits a notification screen display instruction to the client terminal 12 used by the transmission source user, and displays a notification window as shown in FIG. Display 90. As shown in FIG. 8, the notification window 90 lists, among the destination users selected by the source user, those destination users who do not have the right to use the registered content indicated by the link information included in the electronic message. good too.

The sender user can instruct the subsequent processing of the message transmission server 16 in response to the notification from the notification processing unit 52 . In this embodiment, as shown in FIG. 8, the notification window 90 has three buttons, a "Yes" button, a "No" button, and a "Send without deleting" button. By selecting either button, an instruction can be sent to the message sending server 16 .

When the source user selects the "Yes" button, the client terminal 12 transmits to the message transmission server 16 an instruction to transmit the electronic message with the URL deleted. Upon receiving the instruction, the message transmitting unit 48 transmits the electronic message from which the URL of the registered content is deleted to the destination user who does not have the right to use the registered content. As described above, at this time, the message transmitting unit 48 may transmit an electronic message in which the URL of the registered content is not deleted to the destination user who is authorized to use the registered content.

When the transmission source user selects the “No” button, the client terminal 12 transmits an instruction to cancel the transmission of the electronic message to the message transmission server 16 . Upon receipt of the instruction, the message transmitting unit 48 does not transmit the electronic message to any destination user. In this case, the screen (see FIG. 5) before the transmission source user transmits the electronic message is displayed on the display section of the transmission source user's client terminal 12 .

When the source user selects the “send without deleting” button, the client terminal 12 sends an instruction to send the electronic message without deleting the URL to the message sending server 16 . Upon receipt of the instruction, the message transmitting unit 48 transmits an electronic message including link information (URL in this embodiment) of the registered content even to destination users who do not have permission to use the registered content. In other words, when the transmission source user permits the use of the registered content to the transmission destination user who is registered as not having the usage authority of the registered content in the content DB 26 of the content management server 14, the transmission source user does not delete the registered content. button to send the link information of the registered content to the destination user. For example, in the content management server 14, although the destination user is registered as not having the right to use the registered content, the source user can confirm in advance that the destination user is a trustworthy person. Useful if known.

The notification information management unit 54 deletes the link information of the registered content from the message text by the message processing unit 50 and then deletes the link information of the registered content from the message text of the electronic message related to the message request received by the message transmission server 16, and then transmits the electronic message to the destination user. The message and the attribute information of the electronic message are associated and registered in the notification information DB 44 . Electronic messages whose URLs have not been deleted are registered in the notification information DB 44 .

FIG. 9 shows an example of the contents of the notification information DB 44. As shown in FIG. As shown in FIG. 9, in the present embodiment, the notification information DB 44 stores, as attribute information of the electronic message, an electronic message ID that uniquely identifies the electronic message, the registration date and time of the electronic message in the notification information DB 44, and the date and time included in the electronic message. link information (URL in this embodiment), the user ID of the unsent user who is the destination user to whom the electronic message with the link information deleted (that is, the link information was not sent), and the resend Dates and times are associated with each other. The resend date and time is information used to determine whether or not to resend the electronic message (described later), and when the electronic message is registered in the notification information DB 44, the time after a predetermined time from the registration date and time is set. .

The notification information management unit 54 also manages the registration of the destination user indicated by the unsent user ID registered in the notification information DB 44, that is, the destination user to whom the electronic message with the link information of the registered content deleted has been sent. Check content usage rights. In this way, the notification information management unit 54 also functions as a usage authority confirmation unit. Since the destination user indicated by the unsent user ID did not have the right to use the registered content, the electronic message with the link information deleted was sent, but the electronic message with the link information deleted. is transmitted, the destination user may acquire the right to use the registered content. Therefore, the notification information management unit 54 performs the confirmation process to confirm whether or not the destination user is authorized to use the registered content.

Specifically, the notification information management unit 54 selects an electronic message to be processed from the electronic messages registered in the notification information DB 44 . In this embodiment, the notification information management unit 54 selects electronic messages whose retransmission dates and times are earlier than the current time as objects to be processed. It should be noted that other methods can be employed for selecting electronic messages to be processed.

After that, the notification information management unit 54 transmits to the content management server 14 a usage authority confirmation request including the unsent user ID and the link information (URL in this embodiment) of the electronic message to be processed. The content management unit 32 of the content management server 14 refers to the usage authority information in the content DB 26 (FIG. 3), and the user indicated by the user ID included in the usage authority confirmation request is identified by the URL included in the usage authority confirmation request. It is determined whether or not the user has the right to use the registered content (whether or not it can be read), and the determination result is transmitted to the message transmission server 16 . Based on the determination result, the notification information management unit 54 confirms whether or not the destination user has the right to use the registered content.

When the notification information management unit 54 confirms that the destination user to whom the electronic message in which the link information of the registered content has been deleted has obtained the right to use the registered content, the message transmission unit 48 updates the notification information DB 44 based on the electronic message registered in and the unsent user ID, the electronic message whose link information has not been deleted is sent to the destination user. As a result, when the destination user is authorized to use the registered content, the electronic message can be transmitted to the destination user without the need for the transmission source user to send the electronic message again. be.

The notification information management unit 54 performs processing for updating the notification information DB 44 . Specifically, when the electronic message is resent to the unsent user, the notification information management unit 54 deletes the user ID of the user to whom the electronic message was resent from the unsent user ID of the resent electronic message. . Also, the notification information management unit 54 updates the resending date and time of the resent electronic message to the time after a predetermined time from the current time. As described above, in the present embodiment, the notification information management unit 54 selects an electronic message whose resend date and time is later than the current time as a processing target. As long as there is a user, the notification information management unit 54 will repeatedly or intermittently execute the processing for confirming the use authority of the unsent user.

If there is only one unsent user ID for the resent electronic message before the electronic message is resent, there will be no more unsent users for the electronic message after the electronic message is resent. , the electronic message and the attribute information of the electronic message are deleted from the notification information DB 44 .

As a result of confirming the usage authority of the unsent user ID, if it is determined that the unsent user ID does not yet have the usage authority of the registered content, the notification information management unit 54 is subject to confirmation processing. update only the resent date and time of the electronic message sent.

Hereinafter, the flow of electronic message transmission processing in the message transmission system 10 will be described according to the flowchart shown in FIG.

In step S10, the message transmission server 16 sends a message request including the user ID of the source user, the user ID of the destination user, the destination of the message, and an electronic message (message body) from the client terminal 12 of the source user. receive.

In step S12, the message processing unit 50 transmits to the content management server 14 a usage authority confirmation request including the user ID of the destination user received in step S10 and the link information extracted from the electronic message. It is determined whether or not the message contains link information of registered content.

If the electronic message does not contain the link information, or if the link information is contained but not the link information of the registered content ("No" in step S12), the process proceeds to step S26. If the electronic message contains the link information of the registered content ("Yes" in step S12), the process proceeds to step S14.

In step S14, the message processing unit 50 transmits to the content management server 14 a usage authority confirmation request including the user ID of the destination user included in the message request received in step S10 and the link information extracted in step S12.

In step S16, based on the usage authority information in the content DB 26, the content management unit 32 of the content management server 14 determines whether the user indicated by the user ID included in the usage authority confirmation request received in step S14 is included in the usage authority confirmation request. It is determined whether or not the user has the right to use the registered content indicated by the link information.

In step S<b>18 , the content management unit 32 transmits the determination result of step S<b>16 to the message transmission server 16 .

In step S20, based on the determination result received in step S18, the message processing unit 50 determines whether the registered content indicated by the link information extracted in step S12 is among the destination users included in the message request received in step S10. Determine whether or not there is a user without usage authority. If all of the destination users are authorized to use the registered content ("No" in step S20), the process proceeds to step S26. "Yes" in step S20) proceeds to step S22.

In step S22, the notification processing unit 52 notifies the transmission source user that there is a user among the transmission destination users who does not have permission to use the registered content.

In step S24, the message transmission unit 48 determines the instruction of the transmission source user regarding the notification to the transmission source user in step S22.

For example, if the "send without deleting" button in FIG. 8 is pressed and the instruction from the sender is to send an electronic message without deleting the link information ("send as is" in step S24), the process proceeds to step S26. , in step S26, the message transmitting unit 48 transmits an electronic message including link information to all destination users included in the message request received in step S10.

For example, when the "No" button in FIG. 8 is pressed and the transmission source user instructs to cancel the transmission of the electronic message ("transmission is not permitted" in step S24), the message transmission unit 48 cancels the transmission of the electronic message. End the process without sending to any destination user.

For example, if the "Yes" button in FIG. 8 is pressed and the transmission source user instructs to send an electronic message with the link information deleted ("Delete link information" in step S24), the process proceeds to step S28.

In step S28, the message processing section 50 deletes the link information of the registered content from the electronic message.

In step S30, the message transmitting unit 48 transmits the electronic message from which the link information has been deleted in step S28 to the destination user who does not have the right to use the registered content. Here, the message transmitting unit 48 may transmit an electronic message including link information to the destination user who has the right to use the registered content.

In step S<b>32 , the notification information management unit 54 registers the electronic message transmitted in step S<b>30 and the attribute information related to the electronic message in the notification information DB 44 .

Next, the flow of electronic message retransmission processing in the message transmission system 10 will be described according to the flowchart shown in FIG.

In step S<b>40 , the notification information management unit 54 selects, from among the electronic messages registered in the notification information DB 44 , electronic messages whose retransmission dates and times are earlier than the current time as objects to be processed.

In step S42, the notification information management unit 54 transmits to the content management server 14 a usage authority confirmation request including the unsent user ID and link information of the electronic message to be processed selected in step S40.

In step S44, the content management unit 32 of the content management server 14 refers to the usage authority information in the content DB 26 (FIG. 3), and confirms that the user indicated by the user ID included in the usage authority confirmation request received in step S42 It is determined whether or not the registered content indicated by the URL included in the usage authorization confirmation request has usage authorization.

In step S46, the content management unit 32 transmits the determination result in step S44 to the message transmission server 16. FIG.

In step S48, based on the determination result received in step S46, the message transmission unit 48 determines whether or not the unsent user is authorized to use the content. If the unsent user is authorized to use ("Yes" in step S48), the process proceeds to step S50, and if the unsent user is not authorized to use ("No" in step S48), the process proceeds to step S54.

In step S50, the message transmission unit 48 transmits the electronic message to be processed including the link information to the unsent user.

In step S52, the notification information management unit 54 refers to the notification information DB 44, and determines whether or not there is another unsent user in the electronic message to be processed. If there is another unsent user ("Yes" in step S52), the process proceeds to step S54. "No" in step S52) proceeds to step S56.

In step S<b>54 , the notification information management unit 54 updates the attribute information of the electronic message to be processed in the notification information DB 44 . Specifically, the user ID of the user to whom the electronic message was sent in step S50 is deleted from the users to whom the electronic message has not been sent, and the date and time of resending is updated. If the process proceeds from step S48 to step S54 without going through steps S50 and S52, the notification information management unit 54 updates only the resend date and time of the electronic message.

In step S<b>56 , the notification information management unit 54 deletes the electronic message to be processed and its attribute information from the notification information DB 44 .
