An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an overall configuration diagram of a message service system in an embodiment. The message service system comprises user terminals A (10A) to D (10D) and a chat service server 14. FIG.

User terminals A (10A) to D (10D) are terminals used by message service users, and are information terminals such as smartphones, tablet terminals, and PCs (personal computers). In the figure, four units of user terminal A (10A), user terminal B (10B), user terminal C (10C), and user terminal D (10D) are shown, but the number is arbitrary. A plurality of users operate user terminals A (10A) to D (10D) to access the chat service server 14 on the cloud 12 and chat by exchanging messages with other users. In the following, it is assumed that user A operates user terminal A, user B operates user terminal B, user C operates user terminal C, and user D operates user terminal D. FIG. User terminal A (10A) to user terminal D (10D) and chat service server 14 are connected to each other via a wired or wireless communication network so that data can be transmitted and received. An example of a communication network is a public line such as the Internet, but a dedicated line may also be used.

The chat service server 14 is a cloud server arranged on the cloud 12 and is a server that provides chat services. The chat service server 14 is composed of one or more server computers. The chat service server 14 executes overall processing related to message talk exchange, such as message talk transmission/reception processing for user terminals A to user terminals D and display screen display of message talk transmission/reception. The chat service server 14 processes message talk exchanges between two users, as well as processing message talk exchanges within a group (talk group) composed of three or more users. Yes (group chat). Here, message talk refers to data such as text, images, and moving images, and information can be shared by a plurality of people exchanging the data.

FIG. 2 is a functional block diagram of the chat service server 14. As shown in FIG. The chat service server 14 includes a communication unit 140, a message/group control unit 141, a user information storage unit 142, a group information storage unit 143, and a message storage unit 144 as functional blocks.

The communication unit 140 communicates with the user terminals A to D, and exchanges messages between the user terminals A to D. FIG. For example, by receiving a message transmitted from user terminal A and transmitting it to user terminal B, and receiving a message transmitted from user terminal B and transmitting it to user terminal A, establish a talk.

The message/group control unit 141 controls transmission and reception of messages from the user terminals A to D. FIG. It also controls creation and deletion of talk groups. Creating a talk group includes not only creating a new talk group separately from an existing talk group, but also deriving another talk group from an existing talk group. For example, when user A, user B, and user C constitute one talk group and exchange message talks, user D is newly added to the theme related to the theme of this group talk, and user D A, user B, user C, and user D form another talk group. In this case, the original talk group is called a derived talk group, and the derived talk group is called a derived talk group. The derivation destination talk group includes one or more users of the derivation source talk group and is composed of a group of users different from the user group of the derivation source talk group.

The user information storage unit 142 stores information of users who use the chat service. User information includes, for example, a user ID and password, but is not limited to these.

Group information storage unit 143 stores information on the created talk group. The information of the talk group includes, for example, the name of the talk group, users constituting the talk group (constituent members of the talk group), user access rights, etc., but is not limited to this.

The message storage unit 144 stores a group of messages received from user terminals A to D. FIG. The message storage unit 144 particularly stores, for each talk group, message talks exchanged in the talk group.

FIG. 3 is a configuration block diagram of the chat service server 14. As shown in FIG. The chat service server 14 includes, as configuration blocks, one or more CPU 14a, ROM 14b, RAM 14c, communication interface (I/F) 14d, input/output I/F 14e, and storage device 14f.

The one or more CPUs 14a read the processing programs stored in the ROM 14b or the storage device 14f, and use the RAM 14c as a working memory to realize the function of the chat service server. That is, it transmits and receives message talks among user terminals A to D, and creates and deletes talk groups among user terminals A to D. FIG. Creating a talkgroup includes a user interface (UI) for creating a talkgroup. The CPU 14a implements the message/group control section 141 in FIG.

The communication I/F 14d communicates with user terminals A to D. FIG.

The input/output I/F 14e transmits and receives data to and from input devices such as a keyboard and mouse, and output devices such as a display device.

The storage device 14f is composed of a non-volatile memory such as an HDD (Hard Disk Drive) or SSD (Solid State Drive). and store a message management table. The storage device 14f implements the user information storage unit 142, the group information storage unit 143, and the message storage unit 144 in FIG.

In this embodiment, the CPU 14a executes a processing program for realizing the chat service, but part of the chat service may be realized by hardware processing instead of executing the program. Hardware processing may be performed using circuits such as ASIC and FPGA (Field Programmable Gate Array).

FIG. 4 is a functional block diagram of user terminal A as a representative example of user terminals A to D. As shown in FIG. Other user terminal B, user terminal C, and user terminal D also have similar functional block diagrams. The user terminal A includes, as functional blocks, a communication section 10A1, a control section 10A2, and a display section 10A3. In addition to these, input devices such as a mouse and a keyboard that can be operated by the user are provided, but illustration thereof is omitted.

The communication unit 10A1 transmits and receives message talks and various data to and from the chat service server 14 on the cloud 12 .

The control unit 10A2 is composed of one or more CPUs, and controls the operation of each unit by reading and executing a processing program. Control unit 10A2 particularly displays various screens related to talk groups on display unit 10A3 in response to user A's touch operation on the mouse, keyboard, or touch panel, and displays various information related to derived talk groups on the talk group creation screen. Accept and set permissions.

The display unit 10A3 is composed of a liquid crystal display or an organic EL display, and displays message talks to be sent and received under the control of the control unit 10A2. Display unit 10A3 displays a talk group list screen, a talk screen, and a talk group creation screen as display screens. The talkgroup list screen is a screen that displays a list of created talkgroups in a list format. The talk screen is a screen that displays the message talk contents in the talk group in chronological order from top to bottom. The talk group creation screen is a screen for creating a new talk group. Control unit 10A2 displays a talk group list screen, a talk screen, and a talk group creation screen on display unit 10A3 according to an operation from user A. FIG.

Each screen of the talk group list screen, the talk screen, and the talk group creation screen is executed by the control unit 10A2 by reading an application program (client application) stored in the program memory (ROM, HDD, SDD, etc.) of the user terminal A. and displays it on the display unit 10A3. Alternatively, these screens may be created by the chat service server 14 and displayed on the display unit 10A3 by the web client software of the user terminal A. FIG. In the latter case, the message/group control unit 141 of the chat service server 14 creates each screen of a talk group list screen, a talk screen, and a talk group creation screen in response to a request from the user terminal A, and replies to the user terminal A. . Control unit 10A2 displays the talkgroup list screen on display unit 10A3, and switches the display from the talkgroup list screen to the talkgroup creation screen according to user A's operation. Alternatively, control unit 10A2 displays the talk screen on display unit 10A3, and switches the display from the talk screen to the talk group creation screen in accordance with user A's operation. User A creates another talk group (second talk group) from a certain talk group (first talk group) using the talk group creation screen.

When user terminal A creates and displays each screen of a talk group list screen, a talk screen, and a talk group creation screen, user terminal A functions as an information processing device.

When the chat service server 14 creates a talk group list screen, a talk screen, and a talk group creation screen and displays them on the user terminal A, the chat service server 14 functions as an information processing device.

The process of creating a talk group will be specifically described below.

FIG. 5A schematically shows how users A, B, and C form a talk group and have a group chat using a chat service realized by the chat service server 14 . For example, assume that users A, B, and C are employees of a software development company and are engaged in commissioned development of software, and are jointly developing software for company X, a client company. It is assumed that A, User B, and User C form a talk group (first talk group) named "X company project development" and exchange messages and documents.

As the development of Company X's project progressed, it became clear that it would be difficult to realize a certain function Y, and when it was decided to repeatedly discuss this in the talk group "Development of Company X's project," the discussion ended. Among them, regarding the realization of the function Y, it was decided to proceed with the discussion including the user D who is a developer who is not in charge of the company X but who has knowledge about functions similar to the function Y. In addition, there are too many message talks about function Y in the talk group, making it difficult to see discussions about other things.

In such a case, user A creates a new talk group for function Y by deriving it from the talk group "project development for company X", and includes user D in this derived talk group (second talk group).

FIG. 5B schematically shows how user D is newly added, and user A, user B, user C, and user D form a new talk group (second talk group) and conduct group chat. In addition to the talk group "X company project development", a new talk group named "X company project, function Y realization study" is formed to exchange messages and documents.

Here, regarding the newly added user D, if it is assumed that the message talk contents of the derived talk group, that is, the message talk contents of the talk group "X company project development" can be viewed without restriction, a security problem may arise. User D is not directly in charge of development of "Project Development for Company X", and if User D were to be able to know the contents of the message talk, there is a risk that doubts about the confidentiality obligation may arise, and there is no significance in limiting the members. because it can be lost. On the other hand, it would be inconvenient if user D could not view the message talk content of the derivative source talk group, that is, the message talk content of the talk group “Project Development for Company X” at all. If user D does not know the content of the message talk of the derived talk group, user D cannot refer to the discussion about function Y, and how he/she newly joined the talk group and the flow of the discussion up to that point. This is because it is not possible to grasp the

Note that users A, B, and C do not have such a problem. This is because these users are constituent members of the talk group "X company project development" and also constituent members of the talk group "X company project, function Y realization study".

Therefore, the message/group control unit 141 of the chat service server 14 or the control unit 10A2 of the user terminal A enables creation of a derivation destination talk group from a derivation source talk group. By granting User D access rights within a certain range to the message talk of the derivation source talk group, the security of the derivation source talk group is ensured while ensuring the convenience of viewing the derivation source talk group. .

FIG. 6 shows a screen example displayed on the display unit 10A3 of the user terminal A (10A). According to user A's operation, the display unit 10A3 of user terminal A displays a talk group list screen. This screen is displayed when, for example, Web client software installed in user terminal A requests chat service server 14 and receives from chat service server 14 a talk group list screen for user A created by chat service server 14 . be done. In response to a request from the web client software of user terminal A, message/group control unit 141 of chat service server 14 refers to user information storage unit 142 and group information storage unit 143, and reads talk group information to which user A belongs. to create a talk group list screen for user A.

Suppose now that there is a talk group "Project Development for Company X" and that User A, User B, and User C are constituent members of the talk group, the chat service server 14 creates a talk group of which User A is a constituent member. Create a list screen including "X company project development". Control unit 10A2 of user terminal A receives the talk group list screen created by chat service server 14 and displays it on display unit 10A3. As a result, as shown in FIG. 6, only the talk group "X company project development" 100 is displayed on the display unit 10A3 of the user terminal A. FIG.

FIG. 7 shows a state in which the user A right-clicks the mouse, for example, from the state of FIG. 6 and the control section 10A2 displays the menu 102 on the display section 10A3. Note that the right-click operation is an example of a user operation, and is not limited to this, and may be a touch operation, a tap operation, or a voice input operation. In menu 102,
・Each item of addition, deletion, import, export, and derivative talk group creation is displayed. 'Creation of derived talk group' indicates that a new talk group is to be created by deriving from the talk group 'X company project development'. When user A selects "create derived talkgroup" by clicking, for example, control unit 10A2 displays a talkgroup creation screen for creating a derived talkgroup on display unit 10A3. The control unit 10A2 of the user terminal A executes the web client software to request the chat service server 14 to create a talk group from the derivation source talk group "X company project development". In response to this request, the message/group control unit 141 of the chat service server 14 reads the information of the talk group "X company project development" stored in the group information storage unit 143, and creates a talk group creation screen. Reply to user terminal A. Control unit 10A2 of user terminal A receives this talk group creation screen via communication unit 10A1 and displays it on display unit 10A3.

FIG. 8 shows a talkgroup creation screen 104 for creating a derivative talkgroup. Further, FIG. 9 shows the detailed screen. In FIG. 9, as items on the derivative talk group creation screen 104,
・Talk group name ・Members ・Add/delete members ・Derivation source talk group ・Display the talk of the derivation source talk group in the derivation destination talk group ・Choose the talk to display is displayed.

"Talk group name" is the name of the derivation destination talk group, and user A inputs the desired name of the derivation destination talk group in the input field. For example, enter “X company project, function Y realization study”.

"Members" displays the members of the derived talk group as they are. Since users A, B, and C are members of the derivation source talk group “Project Development for Company X”, these user names are displayed.

“Add/delete members” is an item for setting whether to add a new user from the members of the derivation source talk group in the derivation destination talk group, or conversely delete the member. When the pull-down menu is selected, a list of users who are authorized to use the chat service server 14 is displayed, and check marks are displayed for the users of the derived talk group. When user A newly adds a user, user A puts a check mark on the user to be added. The figure shows a case where a check mark is added to the user D in order to newly add the user D. FIG. Conversely, to delete user C, the check mark for user C should be removed.

"Derivation source talk group" displays the name of the derivation source talk group. By visually recognizing this name, user A can confirm the derivation source talk group and use it as a reference when inputting the name of the derivation destination talk group.

``Display the talk of the derivation source talk group in the derivation destination talk group'' is for granting the access authority to the message talk of the derivation source talk group to User D newly added in the derivation destination talk group. item. The figure shows the following two methods for granting access rights.
(1) Message talk within a certain period from the creation of the derived talk group (2) Individually select the message talk to be displayed

Here, the certain period of time can be set arbitrarily, and the default value can be, for example, one week. Assuming that the derivative destination talk group was created on February 21, 2018, message talks from February 14, 2018 to February 21, 2018, for example, are set as display targets in the default state.

The above methods (1) and (2) can be alternatively selected. User A can select either method by ticking the checkbox. FIG. 9 shows the case where method (2) is selected. In this case, control unit 10A2 further displays on display unit 10A3 a screen for individually selecting message talks in the derived source talk group that user D can view.

FIG. 10 shows a message talk selection screen for granting user D access authority. A list of message talk contents of the derivation source talk group is displayed, and user A selects message talk contents that user D can view and puts a checkmark thereon. More specifically, when the user A selects the method (2), the control unit 10A2 of the user terminal A executes the web client software to display the message talk list of the derivation source talk group “X company project development”. to the chat service server 14 . In response to this request, the message/group control unit 141 of the chat service server 14 reads out the message talk list data of the talk group "X company project development" stored in the message storage unit 144 and replies to the user terminal A. . Control section 10A2 of user terminal A receives this message talk list data via communication section 10A1 and displays it on display section 10A3.

User A: Z needs to be considered to realize function Y User B: Mr. D is needed for that User C: I agree operates user terminal A and selects two message talks from these message talks. attached. After that, when the OK button (not shown) or the like on the screen is operated to confirm the selection, the control unit 10A2 of the user terminal A executes the web client software to allow the user D to access the chat service server 14. Send selected message talk information as authority. The message/group control unit 141 of the chat service server 14 receives the message talk information selected as user D's access authority information and stores it in the group information table as user D's access authority.

As described above, the user D who is newly added to the derived talk group is granted access rights within a certain range regarding the message talk of the derived talk group, and the group information storage unit 143 of the chat service server 14 are stored and managed in the group information table of

In FIG. 6, the derivation destination talkgroup is created from the talkgroup list screen, but instead of this, the derivation destination talkgroup may be created from the talk screen.

FIG. 11 shows another screen example displayed on the display unit 10A3 of the user terminal A (10A). According to the user A's operation, the talk screen is displayed on the display unit 10A3. This screen is a talk screen about the talk group "X company project development" created by the message/group control unit 141 of the chat service server 14 when the Web client software installed in the user terminal A requests the chat service server 14. It is displayed by receiving from the chat service server 14 . The message/group control unit 141 of the chat service server 14 refers to the user information storage unit 142, the group information storage unit 143, and the message storage unit 144 in response to a request from the Web client software of the user terminal A, Read the message talk of the talk group "X company project development" to which it belongs and create a talk screen.

Now, let us assume that the content of the message talk in the talk group "Project Development for Company X" is User A: Z needs to be considered in order to realize function Y, User B: Mr. D is required for that, and User C: Agree.

In this state, when the user A right-clicks, for example, the control unit 10A2 displays the menu 102 superimposed on the talk screen. In menu 102,
・Each item of addition, deletion, import, export, and derivative talk group creation is displayed. 'Creation of derived talk group' indicates that a new talk group is to be created by deriving from the talk group 'X company project development'. When user A selects "create derived talk group" by performing a click operation or the like, control unit 10A2 displays a talk group creation screen (see FIG. 9) for creating a derived talk group on display unit 10A3. That is, the control unit 10A2 of the user terminal A executes the web client software to request the chat service server 14 to create a talk group from the derivation source talk group "X company project development". In response to this request, the message/group control unit 141 of the chat service server 14 reads the information of the talk group "X company project development" stored in the group information storage unit 143, and creates a talk group creation screen. Reply to user terminal A. Control unit 10A2 of user terminal A receives this talk group creation screen via communication unit 10A1 and displays it on display unit 10A3.

In the above description, the talk group list screen or the talk screen transitions to the talk group creation screen, and the viewable message talk of the derived talk group is set on the talk group creation screen, but other methods are also possible.

FIG. 12 shows still another screen example displayed on the display unit 10A3 of the user terminal A (10A). According to the user A's operation, the talk screen is displayed on the display unit 10A3 of the user terminal A in the same manner as in FIG. On this talk screen, along with the content of the message talk, a button 108 for "select talk" is displayed at the bottom of the screen. By operating this button 108, it is possible to select a viewable talk for a newly added user in the derived talk group. That is, instead of granting access authority to new users after creating a derivative talk group, the derivative talk group may be created after granting access authority.
