<Details of processing>
Below, the detail of the process of the information processing system 1 which concerns on this embodiment is demonstrated.

《File sharing processing》
The information processing system 1 according to the present embodiment performs a file sharing process as shown in FIG. 8, for example. FIG. 8 is a sequence diagram illustrating an example of file sharing processing. The file sharing process of FIG. 8 includes a chat group creation process and a chat file link transmission process.

  First, in the information processing system 1, the user needs to create a group for transmitting chat conversation contents. For example, the information processing system 1 creates a group for transmitting chat conversation contents as follows.

  In step S11, the user operating the smart device 13A performs a group creation operation on the smart device 13A. In steps S12 and S13, the smart device 13A requests the file server 14 to acquire information on registered users who can participate in the chat. The file server 14 returns the registered user information to the smart device 13A.

  In step S14, the smart device 13A displays a group creation screen as shown in FIG. 9 by using the received registered user information. FIG. 9 is an image diagram of an example of a group creation screen. The group creation screen is an example of a screen displayed on the smart device 13A for group creation. The group creation screen in FIG. 9 includes a field for inputting a group name and a field for selecting a user.

  In step S15, the user operates the smart device 13A and inputs a group name on the group creation screen. In step S16, the user operates the smart device 13A and selects a user to join the group from the group creation screen. In step S17, the user operates the smart device 13A and presses a completion button or the like on the group creation screen to perform a completion operation.

  When the completion operation is performed by the user, the process proceeds to steps S18 and S19, and the smart device 13A creates a group in the file server 14 using the group name input in step S15 and the user selected in step S16. Ask. The file server 14 requested to create the group creates a group using the group name input in step S15 and the user selected in step S16, and manages the users in the same group in association with each other. The file server 14 returns the group ID of the created group to the smart device 13A.

  Thereafter, in the information processing system 1 according to the present embodiment, it is possible to chat between the smart devices 13 participating in the group. FIG. 10 is an image diagram of an example of a group selection screen for chatting.

  The user selects a group to chat from the group selection screen of FIG. 10 and presses the “start conversation button”. The group information displayed on the group selection screen can be acquired from the file server 14. When the button for starting the conversation is pressed, the smart device 13A notifies the chat server 12 of the group ID of the group that performs the chat selected from the group selection screen.

  A chat screen is displayed on the smart devices 13A and 13B operated by the users of the group performing the chat. When it is desired to share a file among users in a group that performs chat, the user performs a file list browsing operation for displaying a file selection screen as shown in FIG. 11 on the smart device 13A in step S20.

  In step S <b> 21, the smart device 13 </ b> A acquires a file list from the file server 14. In step S22, the smart device 13A displays the file selection screen in FIG. FIG. 11 is an image diagram of an example of a file selection screen.

  The file selection screen in FIG. 11 shows an example in which a list of files in the “User A” folder is displayed. In step S23, the user selects a file to be shared among the users in the group from the list of files displayed on the file selection screen, and presses a selection button. When a file is selected from the file list, the smart device 13A designates a group ID in steps S24 and S25, and requests the file server 14 to obtain a file link of the file selected in step S23.

  In step S26, the file server 14 searches for user of the group specified by the specified group ID from the group management information described later based on the group ID specified from the smart device 13A.

  In step S27, the file server 14 determines whether or not the user who does not have the access right to the file selected in step S23 has insufficient access right included in the user searched in step S26. If the access right is insufficient, the file server 14 performs steps S28 to S30.

  In step S28, the file server 14 sets an access right for a user who does not have an access right for the file selected in step S23. In step S29, the file server 14 creates a temporary shared folder that can be accessed by at least the user searched in step S26. If the temporary shared folder has been created, the file server 14 may use the created temporary shared folder.

  In step S30, the file server 14 creates a shortcut for the file selected in step S23 in the temporary shared folder, and returns a file link to the file shortcut to the smart device 13A. If the access right is not insufficient in step S27, the file server 14 returns a file link to the file selected in step S23 to the smart device 13A.

  In step S31, the file server 14 inquires of the chat server 12 for a new message by polling. In step S32, the smart device 13B inquires the chat server 12 for a new message by polling.

  In step S33, the smart device 13A transmits the file link returned from the file server 14 to the chat server 12 as a message. The chat server 12 distributes the file link received as a message from the smart device 13A to the smart devices 13A and 13B and the file server 14.

  Accordingly, in steps S34 to S36, the smart devices 13A and 13B and the file server 14 can acquire the file link selected by the user or the file shortcut in step S23 as a chat message.

  In step S34, the smart device 13A can display the file link to the file or file shortcut selected by the user in step S23 as a message as shown in FIG. FIG. 12 is an image diagram of an example of a chat screen.

  The chat screen of FIG. 12 shows an example in which a message transmitted from the smart device 13A is displayed on the right side and a message transmitted from the smart device 13B is displayed on the left side. In the chat screen of FIG. 12, a file link to the file or file shortcut selected by the user in step S23 is displayed as an icon and a file name as the second message from the smart device 13A.

  In step S35, the file server 14 stores a file link to the file selected by the user or the file shortcut in step S23 as a chat log.

  In step S36, the smart device 13B displays a file link to the file or file shortcut selected by the user in step S23 on the chat screen as a message.

  When the user selects a file link on the chat screen, the smart device 13B acquires a file corresponding to the file link from the file server 14 and displays the contents of the file.

  The file server 14 proceeds to step S37 after a predetermined time has elapsed after adding the access right, and deletes the temporary shared folder and the file shortcut. In step S38, the file server 14 deletes the access right additionally set in step S28, and restores the access right for the file selected in step S23.

  Therefore, for example, the user of the smart device 13B set with the additional access right can access the file until a predetermined time elapses, but cannot access the file after the predetermined time elapses.

  The fixed time from adding the access right to deleting the temporary shared folder and the file shortcut may be reset every time the file link is accessed to extend the time for sharing the file.

  Further, the file link generation process in the file server 14 will be described with reference to FIG. FIG. 13 is a flowchart of an example of the file link generation process. In step S51, the request inquiry unit 35 of the file server 14 receives a file link acquisition request from the smart device 13A.

  In step S52, the user / group management unit 32 of the file server 14 searches the group management information described later for users of the group specified by the specified group ID based on the group ID specified in the file link acquisition request. . In step S53, the file management unit 33 of the file server 14 searches for the user who has the access right of the file for creating the file link from the access right management information described later.

  In step S54, the request processing unit 36 of the file server 14 compares the user searched in step S52 with the user having the file access right searched in step S53. The request processing unit 36 determines whether all the users searched in step S52 have the right to access the file for creating the file link.

  If all the users searched in step S52 have the right to access a file for creating a file link, the file link generation unit 37 generates a file link to the file corresponding to the file link acquisition request from the smart device 13A. To do.

  On the other hand, if at least one of the users searched in step S52 does not have access right to the file for creating the file link, the file management unit 33 assigns access right of the user who does not have access right to the file in step S56. to add.

  In step S57, the file management unit 33 of the file server 14 creates a temporary shared folder that can be accessed by the user searched in step S52. If the temporary shared folder has been created, the file management unit 33 may use the created temporary shared folder.

  In step S58, the file management unit 33 creates a file shortcut for creating a file link in the temporary shared folder. In step S59, the file link generation unit 37 generates a file link to the file shortcut created in the temporary shared folder.

  For example, the relationship among folders, temporary shared folders, files, and file shortcuts in the file link generation process of FIG. 13 is as shown in FIG. FIG. 14 is a diagram showing an example folder structure in the file server.

  The “All User” folder in FIG. 14 is an example of a folder to which all users have access rights. The “User A” folder, “User B” folder, and “User C” folder in FIG. 14 are personal folders to which each user has access rights. The “Group X” folder in FIG. 14 is an example of a temporary shared folder to which a group user has access rights.

  For example, when “file D” in the “User A” folder is selected as a file shared among the users of the group, the request inquiry unit 35 of the file server 14 links the file link “file D” from the smart device 13A in step S51. Accepts an acquisition request.

  In step S52, the user / group management unit 32 of the file server 14 searches the group management information described later for users of the group specified by the specified group ID based on the group ID specified in the file link acquisition request. . Here, it is assumed that user A, user B, and user C have been searched.

  Further, the file management unit 33 of the file server 14 searches the access right management information as shown in FIG. 15 in step S53 for users who have the “file D” access right of the “User A” folder.

  FIG. 15 is a configuration diagram of an example of access right management information. The access right management information shown in FIG. 15 associates file names, access rights, and additional access rights. The file name is an example of information for specifying a file. The access right is an example of information for specifying a user who has an access right for the file specified by the file name. The additional access right is an example of information for specifying a user to which the access right for the file specified by the file name is added.

  In step S54, the request processing unit 36 of the file server 14 compares the user A, the user B, and the user C searched in step S52 with the user A having the “file D” access right.

  The request processing unit 36 determines that among the users A, B, and C searched in step S52, the user B and the user C do not have the “file D” access right, and performs the processes of steps S56 to S59. Do.

  In step S56, the file management unit 33 adds the access rights of the users B and C to “file D” in the “User A” folder to the access right management information in FIG. 15 as additional access rights. The access right management information in FIG. 15 represents a state after the additional access right for “file D” is set.

  In step S57, the file management unit 33 of the file server 14 creates a “Group X” folder as a temporary shared folder. In step S58, the file management unit 33 creates a shortcut for “file D” in the “User A” folder in the “Group X” folder. In step S <b> 59, the file link generation unit 37 generates a file link to the shortcut of “file D” created in the “Group X” folder.

  In the information processing system 1 according to the present embodiment, it is possible to automate the setting of the access right for file sharing between the users who exchange messages on the chat screen by the procedure described above.

  Further, when a user is added to a group before adding the access right and deleting the temporary shared folder and file shortcut, the access right management information and the group management information change as shown in FIG. FIG. 16 is an explanatory diagram showing an example of changes in access right management information and group management information when a user is added to a group.

  The upper part of FIG. 16 represents access right management information and group management information before “user C” is added to “group 1”. The lower part of FIG. 16 represents access right management information and group management information after “user C” is added to “group 1”.

  As shown in the lower part of FIG. 16, when “user C” is added to “group 1” of the group management information, addition of “file A” in which user A and user B of “group 1” are sharing files User C is added to the access right. Therefore, in the information processing system 1 according to the present embodiment, settings for performing file sharing can be automated even for users who join the group halfway.

  Note that when a user is added to a group, group information may be added to access right management information, for example, as shown in FIG. 17 in order to facilitate management of which file the additional access right is added to. FIG. 17 is a configuration diagram of another example of the access right management information.
