Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
<Overview>
FIG. 1 is a system diagram showing a service system configuration.

  As shown in FIG. 1, the service system includes a server (information processing apparatus) 100 and a plurality of user terminals 200A and 200B. Server (information processing apparatus) 100 is connected to user terminals 200 </ b> A and 200 </ b> B via network 400. In FIG. 1, only two user terminals are shown for ease of explanation, but it goes without saying that there may be more user terminals. Moreover, the specific apparatus of the user terminal 200 is not limited to a smart phone as illustrated, and may be a mobile terminal, a tablet terminal, a personal computer, or other electronic apparatus, for example. In the following description, user terminals are collectively referred to as user terminals 200 when there is no particular need for distinction.

  The user terminals 200 </ b> A to 200 </ b> B are equipped with a messaging app provided by the service side and chat using the installed app, as part of a service according to an embodiment of the present invention. The user terminal 200A can form a group together with the user terminal 200B and a plurality of other user terminals (not shown), and can exchange messages between the groups.

  The terminal device 200A may belong to a group that does not include the terminal device 200B. That is, each terminal device can form a plurality of groups together with other terminal devices.

  The service system according to the present invention can extract and share information to be shared from talk room information stored in a server (information processing apparatus) or a partner terminal with which a message is exchanged. Here, as an example, an example will be described in which the service system according to the present invention shares talk room information (including message history information) stored in a partner terminal in FIG. Note that the details of the talk room information and the message history information will be described in <Data> described later.

  For example, when the user (whose user is user C) changes the model of the mobile terminal, the “Let's go! Let ’s go! Good shop” sent at 9:30 as shown in FIG. If you do not have the message history information sent / received before the message “Do you know?”, Swiping the talk room screen where the message was exchanged triggers the operation. A message sharing request is transmitted to the user terminal of the other user (referred to as user A) shown in FIG. Based on the sharing request, the other user terminal obtains the message history information before the latest message history information (message history information transmitted at 9:30) held in the terminal of the user C by the server (information processing Device) 100 and transmits it to user C's terminal. With the transmitted message history information, the message history information that has not been held can be held again and displayed as shown in the dotted frame in FIG. Here, the talk room refers to a virtual space in which messages are exchanged between users using a chat function provided by a messaging app installed in the user terminal 200.

  Thus, even if the past message history information lost due to the terminal model change or the like is not stored in the server (information processing device), it can be acquired and displayed again if it is stored in the terminal of the talk partner. It is possible to provide a highly convenient service for the user.

<Embodiment 1>
<Configuration>
Hereinafter, configurations of the server (information processing apparatus) 100 and the user terminal 200 according to the first embodiment will be described. FIG. 2 is a block diagram illustrating functional configurations of the server 100 and the user terminal 200. As illustrated in FIG. 2, the server 100 includes a communication unit 110, a control unit 120, and a storage unit 130.

  The communication unit 110 includes a reception unit 111 and a transmission unit 112, and has a function of executing communication (various data, message transmission / reception, etc.) with the user terminal 200 via the network 400. The communication may be either wired or wireless, and any communication protocol may be used as long as mutual communication can be performed. Here, the message is not limited to a text message, but includes an image, a sound, a moving image, a stamp (digital sticker), and the like.

  The receiving unit 111 has a function of receiving a message from each user terminal 200 via the network 400 and transmitting data included in the message to the control unit 120. Specifically, for example, the receiving unit 111 includes a talk room information sharing request (hereinafter referred to as “talk room sharing request”) from the user terminal 200 and talk room information corresponding to the talk room sharing request (including message history information). ) And sharing permission information.

  The transmission unit 112 has a function of transmitting a message to each user terminal 200 through the network 400 under the control of the control unit 120. Specifically, for example, the transmission unit 112 sends the user terminal 200 at least a part of the talk room sharing request corresponding to the talk room sharing request and the talk room sharing request, the sharing permission information, and the sharing request received from the other user terminal 200. Send a rejection notice.

  The control unit 120 is a processor that includes an extraction unit 121, a determination unit 122, and a generation unit 123 and has a function of controlling each unit of the server 100.

  Based on the data relating to the talk room sharing request transmitted from the receiving unit 111 (hereinafter referred to as “sharing request data”), the extracting unit 121 uses the talk room information stored in the storage unit 130 as a request target of the data. Has a function to extract data.

  Specifically, the extraction unit 121 provides information used as a search key for extraction included in the sharing request data from the stored talk room information, for example, talk room ID information (to identify the talk room). Unique identification information), user ID information (user-specific identification information given to identify a user), group ID information (group-specific identification given to identify a group in which one or more users are grouped) Information) is searched using at least one of the information as a single key or a composite key, and talk room information matching the key information is extracted. The extraction unit 121 transmits the extracted talk room information and sharing request data to the determination unit as a result of the extraction.

  Based on the talk room information and the sharing request data transmitted from the extracting unit 121, the determining unit 122 has a function of determining whether or not there is information requested to be shared in the talk room information. Specifically, the determination unit 122 includes message ID information (unique identification information given for identifying a message by the server 100 or the user terminal 200 for each talk room information) included in the sharing request data, or a user terminal. 200 based on the oldest transmission date and time information (information indicating the date and time when the user terminal transmitted the message) or reception date and time information (information indicating the date and time when the user terminal received the message) If it is message ID information, message history information having ID information given before the ID information, if it is transmission date information or reception date information, all message history information sent and received before that It is determined that the information is requested for sharing. Here, a sharing request for each message history information has been described as an example, but a sharing request for each talk room information may be used.

  Further, the determination unit 122 can further limit the message history information after the participation date and time based on the date and time information on the user's request for sharing included in the talk room information stored in the storage unit 130. This makes it possible to provide necessary and sufficient range of talk room information to a user who requests sharing of the information without sharing the message history information of the talk room that is not actually participating.

  If the determination unit 122 determines that the information requested to be shared exists as a result of the determination, in order to transmit at least a part of the extracted talk room information to the user terminal 200, the determination result and the talk room information Is transmitted to the transmission unit 112. On the other hand, if it is determined that there is no information to request sharing, based on the user ID information included in the talk room information, a user other than the user who transmitted the sharing request data (user of the sharing request partner) is specified, In order to transmit the talk room sharing request to the user terminal 200 of the identified user, the result of the extraction, the result of the determination and the sharing request data are transmitted to the transmission unit 112, and the result of the extraction, the result of the determination The sharing request data is transmitted to the generation unit 123.

  When the determination unit 122 specifies a user other than the user who transmitted the shared data based on the user ID information included in the talk room information, the determination unit 122 further adds the date and time information that participated in the talk of the sharing request partner user. Based on the user's talk participation date / time of the sharing request, and before the message transmission / reception date / time information, the user who participated in the talk in the sharing target range can be limited. As a result, it is possible to make a request for sharing a talk room only to a partner within a necessary and sufficient range without making a request for sharing the talk room to a user who does not actually participate in the talk.

  Conversely, the determination unit 122 also transmits a talk room sharing request to users who participated in the talk before the participation date and time, and transmitted and received messages before the participation date and time (hereinafter, “share candidate message”). The message history information of the sharing candidate message is also requested to be shared if all the users who participated based on the sharing permission information or at least one or more of the users permitted sharing. The message history information can be transmitted to the transmission unit 112. Thus, if the permission of the user who has participated in the talk is obtained, the talk information before joining the talk can be shared.

  Based on the extraction result, the determination result, and the sharing request data transmitted from the determination unit 122, the generation unit 123 generates information indicating the message to be shared, and the user terminal of the user who is the sharing request partner Display information to be displayed on 200 display units 210 is generated. Here, the information indicating the message of the sharing request target is, for example, a display area indicating the sharing request range by surrounding the target message with a rectangular dotted frame as shown in FIG. Information that clearly indicates the target by highlighting the message balloon frame or character color. The generation unit 123 transmits the generated display information to the transmission unit 112 so as to be included in the message sharing request message and transmitted to the user terminal 200. Thereby, the user of the sharing request partner can visually recognize which message is the target of the sharing request.

  Moreover, the production | generation part 123 can also produce | generate the input display which limits the object which permits sharing among the messages in the said display area. More specifically, for example, the message “Let's go to eat on Saturday at the end of the month!” Sent by user B in FIG. 5B at 18:05 and the dog stamp representing OK sent by user A at 20:00 Is a message to be shared, a check box is provided on the right side of the message, and an input display or the like is limited by selecting a target to be shared. This allows the user of the sharing request partner to allow and reject some messages as well as to allow or reject all of the talk room information requested to be shared, allowing flexible selection Can do.

  Further, as illustrated in FIG. 5A, the generation unit 123 requests the sharing request partner user terminal 200 to share the talk room, and displays whether to permit or reject the sharing of the request. Can also be generated. In addition, as shown in FIG. 5B, it is possible to select to allow only messages limited to the input display that limits the objects to be shared. Thereby, the talk room information memorize | stored in the terminal of the user of a share other party is not shared without permission, but the said talk room information can be shared with the permission of the said user. Furthermore, as shown in FIG. 5C, it is possible to display whether the other user is permitted, not answered, or rejected in addition to the input display. Thereby, it is possible to select whether to permit or reject sharing based on the opinions of other users.

The storage unit 130 has a function of storing various programs, data, and parameters necessary for the operation of the server 100. Specifically, the storage unit 130 includes, for example, talk room information (including message history information) and user information (user ID information and user address information (identification information for transmitting a message to the user terminal 200). , Etc. (which may include identification information unique to the terminal of the user terminal 200). The storage unit 130 is typically realized by various recording media such as an HDD (Hard Disc Drive), an SSD (Solid State Drive), and a flash memory.
The above is the configuration of the server (information processing apparatus) 100 according to the first embodiment.

Next, the configuration of the user terminal 200 according to the first embodiment will be described.
As illustrated in FIG. 2, the user terminal 200 includes a display unit 210, a control unit 220, a communication unit 230, and a storage unit 240.

Specifically, for example, when the receiving unit 231 receives a talk room sharing request from the server 100 and is transmitted to the control unit 220, the control unit 220 permits the sharing request and the sharing transmitted from the display unit 210. Based on the input information to be transmitted, the transmission unit 232 is notified so that at least a part of the talk room information stored in the storage unit 240 is transmitted to the server 100. When the input information for refusing the display unit sharing is transmitted, the control unit 220 transmits the notification of the sharing refusal to the server 100 to be transmitted to the transmission unit 232.

  In addition, the control unit 220 displays the oldest message on the talk room to be saved in the storage unit 240 on the screen of the sharing request target talk room by using, for example, a swipe operation of the screen of the talk room targeted for sharing as a trigger. Triggered by this, or triggered by the installation of the messaging app provided by the server 100, a request for sharing the talk room information can be generated and transmitted to the server 232 to be transmitted to the server 100.

  When installing and triggering the messaging app, user information that is a candidate for a talk partner in the talk room at the time of installation (for example, a user of a user who is recognized as a friend of the user) ID information or the like) or group information that is a candidate for talk participation (for example, group ID information or the like of a group that has participated so far) may be included in the sharing request message. As a result, even if the display unit 210 does not have an input display for executing a talk room sharing request, and there is no user input operation associated therewith, a sharing request can be automatically made. Even when the talk is not started at the time of re-installation, the talk room information to be shared by the server 100 can be searched based on the user information of the talk partner and a sharing request can be made.

  The communication unit 230 includes a reception unit 231 and a transmission unit 232, and has a function of executing communication (various data, message transmission / reception, etc.) with the server 100 via the network 400. The communication may be either wired or wireless, and any communication protocol may be used as long as mutual communication can be performed. Here, the message is not limited to a text message, but includes an image, a sound, a moving image, a stamp (digital sticker), and the like.

The receiving unit 231 has a function of receiving a message from the server 100 or each user terminal 200 via the network 400 and transmitting data included in the message to the control unit 220. Specifically, for example, the receiving unit 231 receives a talk room sharing request (including display information), sharing permission information, and the like from the server 100.

  The transmission unit 232 has a function of transmitting a message to the server 100 or each user terminal 200 through the network 400 according to the control of the control unit 220. Specifically, for example, the transmission unit 232 transmits to the server 100 a talk room sharing request, at least a part of talk room information (including message history information) for the talk room sharing request, sharing permission information, and the like.

The storage unit 240 has a function of storing various programs, data, and parameters necessary for the operation of the server 100. Specifically, the storage unit 240 stores, for example, a messaging application, talk room information (including message history information), user information (including user address information), and the like. The storage unit 240 is typically realized by various recording media such as a hard disk drive (HDD), a solid state drive (SSD), and a flash memory.

Furthermore, the control unit 220 has a function of updating (adding, changing, and deleting) information stored in the storage unit 240 based on the transmitted various information. Specifically, for example, when the receiving unit 231 receives a talk room sharing request from the server 100 and is transmitted to the control unit 220, the control unit 220 permits the sharing request and the sharing transmitted from the display unit 210. Based on the input information to be transmitted, the transmission unit 232 is notified so that at least a part of the talk room information stored in the storage unit 240 is transmitted to the server 100. When the input information for refusing the display unit sharing is transmitted, the control unit 220 transmits the notification of the sharing refusal to the server 100 to be transmitted to the transmission unit 232.

  In addition, the control unit 220 displays the oldest message on the talk room to be saved in the storage unit 240 on the screen of the sharing request target talk room by using, for example, a swipe operation of the screen of the talk room targeted for sharing as a trigger. Triggered by this, or triggered by the installation of the messaging app provided by the server 100, a request for sharing the talk room information can be generated and transmitted to the server 232 to be transmitted to the server 100.

  When installing and triggering the messaging app, user information that is a candidate for a talk partner in the talk room at the time of installation (for example, a user of a user who is recognized as a friend of the user) ID information or the like) or group information that is a candidate for talk participation (for example, group ID information or the like of a group that has participated so far) may be included in the sharing request message. As a result, even if the display unit 210 does not have an input display for executing a talk room sharing request, and there is no user input operation associated therewith, a sharing request can be automatically made. Even when the talk is not started at the time of re-installation, the talk room information to be shared by the server 100 can be searched based on the user information of the talk partner and a sharing request can be made.

  Furthermore, the control unit 220 requests the request for the data from the talk room information stored in the storage unit 240 based on the data related to the toe crew sharing request transmitted from the receiving unit 231 (hereinafter referred to as “sharing request data”). It has a function to extract the data.

  Specifically, the control unit 220 gives information used as a search key for extraction included in the sharing request data from the stored talk room information, for example, talk room ID information (to identify the talk room). Unique identification information), user ID information (user-specific identification information given to identify a user), group ID information (group-specific identification given to identify a group in which one or more users are grouped) Information) is searched using at least one of the information as a single key or a composite key, and talk room information matching the key information is extracted. If the corresponding talk room information cannot be extracted as a result of the extraction, the determination result and the sharing request data are transmitted to the transmission unit 232 in order to transmit a sharing impossible notification to the user terminal 200 that requests the sharing of the talk room. To do.

  The control unit 220 has a function of determining whether there is information to be shared in the talk room information based on the extraction result. Specifically, the determination unit 122 is message ID information based on the message ID information included in the sharing request data or the oldest transmission date / time information or reception date / time information on the talk room held by the user terminal 200. If the message history information having the ID information given before the ID information is transmission date / time information or reception date / time information, all the message history information transmitted / received before that is determined as the information to request sharing. . Here, a sharing request for each message history information has been described as an example, but a sharing request for each talk room information may be used.

  If it is determined as a result of the determination that there is information to request sharing, the control unit 220 transmits the extracted talk room information or the like to the user terminal 200 that requests sharing. At least part of the information is transmitted to the transmission unit 232. On the other hand, when it is determined that there is no information to request sharing, the sharing result notification and the sharing request data are transmitted to the transmission unit 232 in order to transmit a sharing impossible notification to the user terminal 200.

  Based on the extraction result and the sharing request data, the control unit 220 generates display information that causes the display unit 210 to display information indicating the message to be shared. Here, the information indicating the message of the sharing request target is, for example, a display area indicating the sharing request range by surrounding the target message with a rectangular dotted frame as shown in FIG. Information that clearly indicates the target by highlighting the message balloon frame or character color. The control unit 220 transmits the generated display information to the display unit 210. As a result, the user can visually recognize which message is the target of the sharing request.

  In addition, the control unit 220 can also generate an input display that limits the objects that are allowed to be shared among the messages in the display area. More specifically, for example, the message “Let's go to eat on Saturday at the end of the month!” Sent by user B in FIG. 5B at 18:05 and the dog stamp representing OK sent by user A at 20:00 Is a message to be shared, a check box is provided on the right side of the message, and an input display or the like is limited by selecting a target to be shared. This allows the user of the sharing request partner to allow and reject some messages as well as to allow or reject all of the talk room information requested to be shared, allowing flexible selection Can do.

  Further, as shown in FIG. 5A, the control unit 220 can also generate an input display as to whether or not to allow sharing to be displayed on the display unit 210. In addition, as shown in FIG. 5B, it is possible to select to allow only messages limited to the input display that limits the objects to be shared. Accordingly, the talk room information stored in the user terminal can be shared without permission, and the talk room information can be shared with the permission of the user held with the user terminal. Furthermore, as shown in FIG. 5C, it is possible to display whether the other user is permitted, not answered, or rejected in addition to the input display. Thereby, it is possible to select whether to permit or reject sharing based on the opinions of other users.

  The communication unit 230 includes a reception unit 231 and a transmission unit 232, and has a function of executing communication (various data, message transmission / reception, etc.) with the server 100 via the network 400. The communication may be either wired or wireless, and any communication protocol may be used as long as mutual communication can be performed. Here, the message is not limited to a text message, but includes an image, a sound, a moving image, a stamp (digital sticker), and the like.

  The receiving unit 231 has a function of receiving a message from the server 100 or each user terminal 200 via the network 400 and transmitting data included in the message to the control unit 220. Specifically, for example, the receiving unit 231 receives a talk room sharing request (including display information), sharing permission information, and the like from the server 100 and another user terminal 200.

  The transmission unit 232 has a function of transmitting a message to the server 100 or each user terminal 200 through the network 400 according to the control of the control unit 220. Specifically, for example, the transmission unit 232 sends a talk room sharing request to the server 100 and other user terminals 200, at least a part of talk room information (including message history information) for the talk room sharing request, sharing permission information, and Sends a sharing impossible notification.

The storage unit 240 is the same as that in the first embodiment.
The above is the configuration of the user terminal 200 according to the second embodiment.

<Data>
Here, FIG. 3 shows a data configuration example of the talk room information stored in the storage unit 130 in the present embodiment. FIG. 3 is a data conceptual diagram showing a data configuration example of talk room information.

  The talk room information is exchanged between users in a specific talk room stored in the storage unit 130 of the server 100 or the storage unit 210 of the user terminal 200, group information, and users in the talk room 1 The above-described message history information (here, “N” in “× N” in FIG. 3 indicates a number of 1 or more). The talk room information is not limited as long as it includes all items shown in the data structure shown in FIG. The talk room information stored in the server 100 and the user terminal 200 may be associated with identification information such as a talk room ID, or may not be associated with the identification information. Furthermore, even if the association is made, the information of other items may be different (for example, even if the same talk room ID and the same message ID are used, the contents of the message text and the like are different). ).

  The talk room ID is unique identification information given by the server 100 to identify a talk room talk. The user ID is unique identification information given by the server 100 to identify the user. The group ID is unique identification information given by the server 100 to identify the group.

  Message history information includes message ID information, message text, stamp ID information (unique identification information given to identify the stamp), image data of the stamp, image data, transmission user ID information (the target message has been transmitted) User ID information of users), transmission date information (date and time information when the target message was transmitted), reception user ID information (user ID information of all users who received the target message), reception date information (received) Information on the date and time when the target message is received for each user. The message history information is stored for one message exchanged in the talk in one talk room information. Further, the message history information can include a MAC (Message Authentication Code) value of each message data. Furthermore, the message once transmitted can be corrected later, and the storage unit 130 can also store message history information (including the MAC value) for each correction.

  Further, when all or part of the message history information cannot be stored in the server 100 due to various circumstances such as security, protection of personal information and capacity of the storage unit 130, the message history information is stored after a predetermined period. The unit 130 may delete the target message history information. For example, as shown in FIG. 3A, with respect to the message IDs “Msg0011” and “Msg0012” that are initially stored, data other than the message ID is deleted as shown in FIG. May be. When a message sharing request for the message history information is received in a state where the message history information of “Msg0011” and “Msg0012” is erased, the user ID “User0022”, “User0101” or “User0078” The message history information held in the user terminal 200 of the user is requested to be shared.

  Further, when the message history information to be shared is corrected, the generation unit 123 displays at least one of a display indicating that the message is corrected or an input display for selecting which message to be shared before or after the correction. In order to transmit display information including two or more to the user terminal 200 of the user who requests sharing, the display information is generated, the generated display information is transmitted to the transmission unit 112, and the transmission unit 112 transmits the displayed display information. Can be transmitted to the user terminal 200. As a result, the user who requests sharing can know the correction when the message has been corrected later, and also selects the message before and after the correction and restores (acquires) the message history information. )be able to.

Furthermore, when erasing the message history information stored in the storage unit 130 of the server 100, the MAC value of each message can be left. If the message history information for each correction is not held, the determination unit 122 Can compare the MAC value of the message history information to be shared received from the user terminal 200 with the MAC value left in the storage unit 130 of the server 100 to determine whether the message has been modified. Specifically, the determination unit 122 compares whether or not these MAC values match. If the MAC values match as a result of the comparison, the determination unit 122 determines that the message has not been modified, and the MAC values do not match. Can determine that the message has been modified. When it is determined that the message has been modified, the unmodified message history information received from other user terminals may be preferentially shared (sent to the user terminal 200 of the user who requests sharing), or The unit 122 transmits the result of the determination to the generation unit 123, and the generation unit 123 that has received the determination result shares a message indicating that the message has been corrected or which message before or after the correction is shared. In order to generate display information including at least one or more input displays to be selected and transmit the generated display information to the user terminal 200 of the user who requests sharing, the display information is transmitted to the transmission unit 112 and the transmission unit 112 May transmit the transmitted display information to the user terminal 200. As a result, even if a part of the message history information to be shared is deleted in the server 100, the user who requests sharing can know the correction when the message has been corrected later, and before the correction. And the message history information can be restored (obtained) by selecting the corrected message.
The above is an example of the data structure of talk room information.
