Next, the access process to the security folder after the shared service is started in step S106 shown in FIG. 3 will be described with reference to FIGS. 7 and 8. FIG. 7 is a sequence diagram showing an example of failure in access processing to the security folder in the file sharing system 100 according to the first embodiment.

As shown in FIG. 7, the control unit 24 of the terminal device 20 transmits an access signal to the security folder to the storage device 10 according to the user's operation on the input unit 23 (S121). This access signal includes the security folder path.

Since the control unit 13 of the storage device 10 has not yet provided the security folder sharing service, it does not respond to the access signal (S122). That is, since the path of the security folder does not exist yet, the response signal to the access signal is not transmitted to the terminal device 20. For example, when the user tries to open a file in the security folder from a recently used item of the application, the application displays an error because there is no response from the storage device 10.

The control unit 24 of the terminal device 20 displays an error message on the display unit 22 when the elapsed time from the time when the file operation signal is transmitted exceeds the threshold time (S123).

As described above, even if the normal shared folder sharing service is provided, the security folder sharing service has not been enabled yet, so the security folder does not exist on the network.

Next, a method for accessing the security folder will be described with reference to FIG. FIG. 8 is a sequence diagram showing a successful example of access processing to the security folder in the file sharing system 100 according to the first embodiment.

As shown in FIG. 8, first, the control unit 24 of the terminal device 20 transmits an unlock signal of the security folder to the storage device 10 (S131). This unlock signal contains the security key corresponding to the security folder. The GUI for transmitting the unlock signal will be described later with reference to FIG.

The control unit 13 of the storage device 10 identifies the security folder and the user corresponding to the security key included in the unlock signal, and enables the shared service for the specified user for the specified security folder (S132). .. As a result, the response signal including the shared name of the security folder is transmitted from the storage device 10 to the terminal device 20. The details of the process in step S132 will be described later with reference to FIG. Both the unlock signal and the response signal are transmitted by the HTTPS communication protocol.

The control unit 24 of the terminal device 20 displays the first display on the display unit 22 based on the response signal transmitted from the storage device 10 (S133). The first display is an example of a display (image) indicating that the security folder sharing service has been enabled. The user can easily grasp that the security folder sharing service has been activated by looking at the first display displayed on the display unit 22. A display example of the first display will be described later with reference to FIG.

The control unit 24 of the terminal device 20 transmits an operation signal for accessing the security folder to the storage device 10 based on the shared name of the security folder included in the response signal (S121).

The control unit 13 of the storage device 10 requests authentication information from the terminal device 20 when the user of the terminal device 20 is not authenticated (S112). The control unit 24 of the terminal device 20 displays, for example, an authentication screen on the display unit 22. Then, the control unit 24 accepts the input of the authentication information (for example, the user ID and the password) from the user via the input unit 23 (S113). The entered authentication information is transmitted to the storage device 10. The control unit 13 of the storage device 10 performs user authentication based on the authentication information received from the terminal device 20 (S114). Then, based on the authentication result, the response signal to the access signal is transmitted from the storage device 10 to the terminal device 20.

Conventional technology may be used for the process related to user authentication in steps S112 to S114. If the user of the terminal device 20 has already been authenticated, the processes of steps S112 to S114 may be skipped.

The control unit 24 of the terminal device 20 receives an input for file operation from the user and transmits a file operation signal to the storage device 10 (S115).

When the user authentication is successful, the control unit 13 of the storage device 10 performs a file operation corresponding to the file operation signal based on the access authority of the user, and transmits a response signal corresponding to the operation result to the terminal device 20. (S134). The details of the process in step S134 will be described later with reference to FIG.

When the operation for the file in the security folder is completed, the control unit 24 of the terminal device 20 transmits the lock signal to the storage device 10 based on, for example, the user's operation on the input unit 23 (S135). Note that, for example, when the elapsed time from the time when the security folder was last operated is equal to or longer than the threshold time, the control unit 24 may transmit the lock signal to the storage device 10. That is, when the operation for the security folder is not executed for the threshold time or more, the control unit 24 may transmit the lock signal to the storage device 10.

The control unit 13 of the storage device 10 disables the security folder sharing service when a predetermined condition is satisfied (S136). At this time, the control unit 13 deletes the record registered in the shared state table described later.

The predetermined condition is, for example, to receive the lock signal transmitted from the terminal device 20. Alternatively, the predetermined condition may be, for example, that the elapsed time from the time when the security folder was last accessed is equal to or longer than the threshold time.

The control unit 24 of the terminal device 20 transmits an inquiry signal to the storage device 10 (S137). The control unit 13 of the storage device 10 transmits a response signal indicating that the shared service of the security folder has been disabled to the terminal device 20 based on the inquiry signal transmitted from the terminal device 20 (S138). The control unit 24 of the terminal device 20 can determine that the shared service of the security folder has been disabled based on the response signal transmitted from the storage device 10.

The control unit 24 of the terminal device 20 changes the first display displayed on the display unit 22 to the second display based on the response signal transmitted from the storage device 10 (S139). The second display is an example of a display (image) indicating that the shared service of the security folder has been disabled. By looking at the second display displayed on the display unit 22, the user can easily grasp that the security folder sharing service has been disabled. A display example of the second display will be described later with reference to FIG.

The control unit 24 of the terminal device 20 outputs a sound effect from the voice output unit 25 when the first display is changed to the second display (S140). When a predetermined time (for example, 3 seconds) has elapsed since the security folder sharing service was disabled, the control unit 24 of the terminal device 20 hides the second display displayed on the display unit 22 (for example, 3 seconds). S141).

The second display may be constantly displayed on the display unit 22 by omitting step S141 described above. Further, when displaying the first display on the display unit 22 (S133), the sound effect may be output from the voice output unit 25.

[1-4-6. Unlocking signal transmission screen]
Here, an example of the unlocking signal transmission screen displayed in step S131 shown in FIG. 8 will be described with reference to FIG. FIG. 9 is a diagram showing an example of an unlocking signal transmission screen according to the first embodiment.

As shown in FIG. 9A, the control unit 24 of the terminal device 20 has a first context when an operation (for example, a click of the right mouse button) by the input unit 23 for the icon 51 on the task bar is detected. The menu 52 is displayed on the display unit 22. Here, when an operation by the input unit 23 for "SF unlocking" in the first context menu 52 (for example, a click of the left mouse button (hereinafter referred to as "left click")) is detected, the control unit 24 performs. , The second context menu 53 is displayed on the display unit 22.

In the second context menu 53, each item of the security folders "SF1", "SF2" and "SF3" in which the security key is registered in advance in the terminal device 20, and the security folder in which the security key is not registered in the terminal device 20 "Arbitrary" items for are displayed.

Here, when an operation (for example, left-click) by the input unit 23 for "arbitrary" in the second context menu 53 is detected, as shown in FIG. 9B, the control unit 24 uses the security key. The input dialog 54 is displayed on the display unit 22. The user obtains a security key from, for example, an administrator, and inputs the obtained security key in the input dialog 54. Here, if an operation (for example, left-clicking) for the "OK" button in the input dialog 54 is detected, the control unit 24 transmits an unlock signal including the security key input in the input dialog 54 to the storage device 10. do.

On the other hand, when an operation (for example, left click) by the input unit 23 for "SF1", "SF2" or "SF3" in the second context menu 53 is detected, the control unit 24 moves to the operated security folder. The security key registered in advance in the terminal device 20 is read out in association with each other, and the unlock signal including the security key is transmitted to the storage device 10.

The control unit 24 of the terminal device 20 may transmit the unlock signal to the storage device 10 without using such a transmission screen. For example, when the control unit 24 detects a specific operation (for example, mouse gesture or shortcut key input) by a keyboard or a mouse, the control unit 24 sends an unlock signal including a security key corresponding to the specific operation to the storage device 10. You may send it.

[1-4-7. Security folder sharing service activation process]
Next, with reference to FIG. 10, the process of enabling the security folder sharing service in step S132 shown in FIG. 8 will be specifically described. FIG. 10 is a flowchart showing an activation process of the shared service by the storage device 10 according to the first embodiment.

As shown in FIG. 10, the control unit 13 of the storage device 10 acquires a security key from the unlock signal (S1321).

Then, the control unit 13 determines whether or not the acquired security key is registered in the shared setting table (S1322). That is, the control unit 13 determines whether or not the security key included in the unlock signal matches the security key included in the shared setting table. For example, in the shared setting table 40 shown in FIG. 5, any one of the security keys "SF1-KEY1", "SF1-KEY2", "SF2-KEY1", "SF2-KEY2", and "SF2-KEY3" is used for the unlock signal. If is included, the control unit 13 determines that the acquired security key is registered in the shared setting table 40.

Here, when the security key is registered in the sharing setting table (Yes in S1322), the control unit 13 enables the sharing service of the security folder corresponding to the security key to the user associated with the security key. (S1323). For example, in the shared setting table 40 shown in FIG. 5, when the security key "SF1-KEY1" is included in the unlock signal, the control unit 13 sets the shared service of the security folder with the shared name "SF1" to ". Enable for "USER1".

Further, the control unit 13 registers the shared name of the activated security folder, the IP (Internet Protocol) address of the source of the unlocking signal, and the user ID in the shared status table (S1324). The IP address of the source can be obtained from the unlock signal. After that, the control unit 13 transmits the shared name of the security folder to the terminal device 20 (S1325).

On the other hand, when the security key is not registered in the shared setting table (No in S1322), the control unit 13 transmits an error response to the terminal device 20 (S1326). That is, when the security key included in the unlock signal does not match the security key registered in the shared setting table, the control unit 13 prohibits the activation of the shared service of the security folder.

[1-4-8. Specific example of shared status table]
Here, a specific example of the shared state table in step S1325 shown in FIG. 10 will be described with reference to FIG. FIG. 11 is a diagram showing an example of the shared state table 60 according to the first embodiment.

As shown in FIG. 11, the shared state table 60 includes a shared name 61, an IP address 62, and a user ID 63.

In the shared name 61, the shared name of the security folder corresponding to the security key included in the unlock signal, that is, the security folder in which the shared service is enabled is registered. The IP address of the source of the unlocking signal is registered in the IP address 62. The user ID included in the unlock signal is registered in the user ID 63.

For example, when the storage device 10 receives an unlock signal including the security key "SF1-KEY1" from the terminal device 20 having an IP address of "192.168.0.1", "SF1" is shown in FIG. , "192.168.0.1" and "USER1" are registered in the shared state table 60.

[1-4-9. Display examples of the first display and the second display]
Next, with reference to FIG. 12, each display example of the first display in step S133 and the second display in step S139 shown in FIG. 8 will be described. FIG. 12 is a diagram showing each display example of the first display 81 and the second display 91 according to the first embodiment.

As shown in FIG. 12A, the display unit 22 of the terminal device 20 displays a window 70 for displaying the security folder 71 having the shared name “SF1”. For example, when the shared service of the security folder 71 is enabled, the first display 81 is displayed on the display unit 22. The first display 81 is, for example, a translucent window and includes a first icon 82 which is an image showing an unlocked lock inside. By looking at the first icon 82 displayed on the display unit 22, the user can easily grasp that the shared service of the security folder 71 has been activated.

Further, the first display 81 includes a counter 83. The counter 83 is a display (so-called badge) indicating the number of security folders for which the shared service is enabled. For example, if the number of security folders for which the shared service is enabled is one, the counter 83 displays "1". Similarly, if the number of security folders for which the shared service is enabled is 10, the counter 83 displays "10". By looking at the counter 83, the user can easily grasp the number of security folders for which the shared service is enabled. The counter 83 is not essential and may be omitted.

Further, the first display 81 includes a lock button 84. The lock button 84 is a button for locking the security folder (that is, disabling the security folder sharing service). The control unit 24 of the terminal device 20 transmits a lock signal to the storage device 10 when an operation (for example, left click) by the input unit 23 for the lock button 84 is detected. For example, when there are a plurality of security folders for which the shared service is enabled, the shared services of all the security folders are disabled at once by the above operation.

As shown in FIG. 12B, when the shared service of the security folder 71 is disabled, the first display 81 is changed to the second display 91. The second display 91 is, for example, a translucent window and includes a second icon 92 which is an image showing a locked lock. By looking at the second icon 92 displayed on the display unit 22, the user can easily grasp that the shared service of the security folder 71 has been disabled.

Further, the second display 91 includes a counter 93. Similar to the counter 83 described above, the counter 93 is a display (so-called badge) indicating the number of security folders for which the shared service is enabled. If the number of security folders for which the shared service is enabled is 0, the counter 93 displays "0". In this case as well, the counter 93 is not essential and may be omitted.

Further, the second display 91 includes a character display 94. The character display 94 is a character display indicating that the security folder is locked (that is, the security folder sharing service is disabled). The character display 94 may be used as a button, and the security folder may be unlocked again by an operation (for example, left-clicking) by the input unit 23 for the character display 94.

[1-4-10. File operation processing]
Next, with reference to FIG. 13, the operation process of the file in the security folder in step S134 shown in FIG. 8 will be specifically described. FIG. 13 is a flowchart showing a file operation process by the storage device 10 according to the first embodiment.

As shown in FIG. 13, the control unit 13 of the storage device 10 acquires the shared name of the security folder, the user ID, and the IP address of the transmission source from the file operation signal (S1341). By referring to the shared status table, the control unit 13 determines whether or not the acquired shared name is registered in association with the acquired user ID and IP address (S1342). That is, the control unit 13 determines whether or not the security folder sharing service is enabled, and whether or not the terminal device 20 that is the source of the file operation signal matches the terminal device 20 that is the source of the unlock signal. To judge.

Here, when the shared name is registered in association with the user ID and IP address (Yes in S1342), the control unit 13 performs a file operation corresponding to the file operation signal based on the user's access authority. Then, the response signal corresponding to the operation result is transmitted to the terminal device 20 (S1343). That is, when the terminal device 20 that is the source of the file operation signal matches the terminal device 20 that is the source of the unlock signal, the control unit 13 permits the file operation corresponding to the file operation signal.

On the other hand, when the shared name is not associated with the user ID and the IP address (No in S1342), the control unit 13 transmits an error response to the terminal device 20 (S1344). That is, when the terminal device 20 that is the source of the file operation signal does not match the terminal device 20 that is the source of the unlock signal, the control unit 13 prohibits the file operation corresponding to the file operation signal.

For example, in the shared state table 60 shown in FIG. 11, a file operation signal for a file in the security folder of "SF1" from a user of user ID "USER1" in a terminal device having an IP address "192.168.0.1". Is transmitted, the file operation corresponding to the file operation signal is permitted.

On the other hand, when a file operation signal for a file in the security folder of "SF1" is transmitted from a user of user ID "USER2" in a terminal device having an IP address "192.168.0.1", the file operation is performed. File operations corresponding to signals are prohibited. That is, if a file operation signal is transmitted from a user different from the user who transmitted the unlock signal, the file operation corresponding to the file operation signal is prohibited.

Further, when a file operation signal for the security folder of "SF1" is transmitted from the user of the user ID "USER2" in the terminal device 20 having the IP address "192.168.0.2", the file operation signal is used. The corresponding operation is prohibited. That is, if a file operation signal is transmitted from a terminal device different from the terminal device 20 from which the unlock signal is transmitted, the file operation corresponding to the file operation signal is prohibited.

[1-5. effect]
