At least a mobile terminal among the plurality of terminals has a push notification reception function. At least a mobile terminal among the plurality of terminals has a plurality of application programs including one or more application programs including a secure browser function and a push notification receiving function. The secure browser function is a browser function that erases information input / output from / to a terminal that executes the secure browser function from the terminal. In the case of information sharing, one or more sharing targets registered in storage means (for example, a storage device in or outside the information sharing support system) are displayed on the browser screen of the browser of each terminal. Each of the one or more sharing targets is information including a sharing input target input as information shared in an information sharing place from any terminal. The information sharing support system has a push notification reception function of a mobile terminal as another terminal of a plurality of terminals when a shared object including a shared input object newly input from any terminal is newly registered in the storage unit In response, a notification for starting the secure browser function of the mobile terminal is transmitted. The push notification reception function activates the secure browser function by using the received notification. In response to the request from the activated secure browser function, the information sharing support system transmits the newly registered display information to be shared to the secure browser function.

  The secure browser function and the push notification reception function may be functions included in one application program, or may be functions included in separate application programs.

  It is possible to provide a new information sharing technique suitable for sharing highly important information.

  FIG. 1 shows a configuration of an information sharing system according to an embodiment of the present invention.

  There are a plurality of smartphones 20 used by a plurality of users and an information sharing support system 61. Each smartphone 20 communicates with the information sharing support system 61 via a communication network (for example, the Internet or a dedicated network) 10. The information sharing support system 61 includes a secure gateway 50 and an information sharing support server 70. Each smartphone 20 communicates with the information sharing support server 70 via the secure gateway 50. Each of the secure gateway 50 and the information sharing support server 70 is a physical computer machine (for example, one or more computers), but each of them may be a virtual machine executed on the same or different computer machine. .

  The smartphone 20 is an example of a mobile terminal. The smartphone 20 is a kind of smart device. A smart device is a multifunctional mobile terminal that can be used not only for calculation processing but also for various purposes. The smartphone 20 includes a touch panel 211, a storage resource 213, a sensor group 295, a camera 214, an I / F 216, and a processor 212 connected to them. The sensor group 295 is a set of one or more sensors, and includes, for example, a GPS (Global Positioning System) sensor, a gyro sensor, and the like. In the present embodiment, the “storage resource” is a set of one or more storage devices, and includes, for example, a main storage memory and an auxiliary storage device. In this embodiment, the “processor” is typically a CPU (Central Processing Unit), but includes a hardware circuit (for example, a circuit that performs encryption and / or decryption) that performs predetermined processing. But it ’s okay. In this embodiment, “I / F” is a set of one or more communication interface devices. For example, the I / F 216 includes a communication interface device for performing communication via the communication network 10, and other types. And a communication interface device for performing communication.

  The storage resource 213 stores a plurality of computer programs executed by the processor 212, for example, a secure browser 221 and a write notification APP (application program) 222. At least one of the secure browser 221 and the write notification APP 222 may be preinstalled or may be installed from a predetermined program source. Hereinafter, the processing may be described with the computer program as the subject, but the processing is performed by the processor 212 that executes the computer program.

  The secure browser 221 is, for example, a web browser and is a kind of APP (application program). The secure browser 221 prevents information input on a screen (hereinafter referred to as a browser screen) displayed by the secure browser 221 or information in the screen displayed by the secure browser 221 from remaining on the smartphone 20. Specifically, for example, the secure browser 221 writes the information on the browser screen in a cache area provided in the storage resource 213, but when the secure browser 221 ends or before that, the secure browser 221 enters the cache area. All written information is erased from the cache area. The input of the sharing input target and the browsing of the sharing target are performed using the secure browser 221. In this embodiment, the “shared input target” is an electronic information sharing place provided by the information sharing support server 70 (hereinafter referred to as “bulletin board” for convenience) and is input through the secure browser 221 and shared by a plurality of members. Say information to be. The shared input target may be only a character string (sentence), or instead of or in addition to the character string, sound, an image (for example, an image photographed by the camera 214), information detected by the sensor group 295 (for example, a GPS sensor) At least one of position information detected by the sensor group 295 and information specified based on the information detected by the sensor group 295 (for example, a place name specified using the position information detected by the GPS sensor). May be included. The “shared object” may be information including the shared input object, for example, only the shared input object, or a set of the shared input object and related information associated with the shared input object. The related information includes, for example, the time when the shared input target is registered on the bulletin board (for example, the time specified from the timer (not shown) of the information sharing support server 70) and the member (user) who inputs (registers) the shared input target. ) And the number and names of members who viewed the shared input target.

  The write notification APP 222 is an APP that receives a notification from the information sharing support server 70 when a sharing target corresponding to the condition is newly added to the information sharing support server 70. “The sharing target corresponding to the condition” is a sharing target registered on a bulletin board having one user who owns the smartphone 20 that executes the APP as one of the members.

  The secure gateway 50 relays communication between each smartphone 20 and the information sharing support server 70. The secure gateway 50 includes an I / F 51 that communicates via the communication network 10, an I / F 52 that communicates with the information sharing support server 70, a storage resource 54, and a processor 53 connected thereto. The processor 53 performs device authentication of the smartphone 20 and permits communication between the smartphone 20 determined to be valid in the device authentication and the information sharing support server 70. In device authentication, for example, the processor 53 receives a certificate issued to the smartphone 20 registered as a device from the smartphone 20 and determines whether the certificate is valid. The certificate issued to the smartphone 20 is stored in the storage resource 213 of the smartphone 20, for example, and is received from the secure browser 221 for device authentication.

  The information sharing support server 70 includes an I / F 71 that communicates with the secure gateway 50, a storage resource 73, and a processor 72 connected to them. The storage resource 73 stores a plurality of computer programs executed by the processor 72, for example, a user authentication program 730 and an information sharing support program 731. The storage resource 73 stores user management data 762 and a bulletin board data unit 740 for each bulletin board. At least a part of the user management data 762 and the plurality of bulletin board data units 740 is stored in an external storage device (not shown) that can communicate with the information sharing support server 70 instead of or in addition to the storage resource 73. May be. There are a plurality of members (users) for each bulletin board.

  The user authentication program 730 performs user authentication of the user of the smartphone 20. In user authentication, for example, the user authentication program 730 determines whether the ID and password input by the user are correct.

  The information sharing support program 731 provides information for displaying a bulletin board or the like on the secure browser 221 of the smartphone 20. In addition, when a sharing target is added to any bulletin board, the information sharing support program 731 notifies the writing notification APP 222 of the smartphone 20 of all members of the bulletin board (excluding the user who added the sharing target). Send.

  The user management data 762 is data related to each of a plurality of users, for example, a name, ID, password, telephone number (phone number of the smartphone 20), e-mail address, and address used for issuing a notification to the write notification APP of the smartphone 20. Includes information.

  The bulletin board data unit 740 includes management data 732, detailed data 734, and summary data 735. The management data 732 includes management data related to the bulletin board, for example, the title of the bulletin board and data (for example, name) related to the members of the bulletin board. Detailed data 734 includes detailed data related to all sharing targets registered on the bulletin board (for example, for each sharing target, the sharing input target and related information (for example, the sharing target ID, the name of the member who registered the sharing input target, And the number of members who have viewed the sharing target and the name). The summary data 735 is data related to the summary among all the shared input targets registered in the bulletin board (for example, data including the summary target and the ID of the shared target that is the source of the summary target for each summary target). is there.

  Hereinafter, with reference to FIGS. 2A to 4B, the information is displayed by the secure browser 221 based on the information transmitted to the secure browser 221 of the smartphone 20 through the secure gateway 50 by the information sharing support server 70 (information sharing support program 731). The browser screen will be described. In the following description, the information sharing support server 70 (information sharing support server 70 (information sharing support program 731) indicates that the information is displayed by the secure browser 221 based on the information transmitted to the secure browser 221. The sharing support program 731) may display information on the secure browser 221 ". The screen shown in each of FIGS. 2A to 4B is a browser screen. Further, it is assumed that there is one management member (member as an administrator) among a plurality of members of the bulletin board.

  FIG. 2A shows an example of the bulletin board start screen.

  The bulletin board start screen 200 is displayed on the secure browser 221 by the information sharing support server 70 (information sharing support program 731) based on the management data 732 (see FIG. 1) of the bulletin board corresponding to this screen. The bulletin board start screen 200 includes a bulletin board title field 207, a member field 205, a member edit button 202, a detail button 203, and a summary view button 204.

  In the bulletin board title field 207, a character string (for example, “system failure A”) of a bulletin board title input by a management member (for example, a user who newly started up a bulletin board) is displayed.

  The member field 205 displays a list of names of all members registered by the management member. The secure browser 221 can scroll the list displayed in the member field 205 up and down in response to a scroll operation (for example, up and down swipe) performed on the field 205.

  The member edit button 202 is a button that is pressed (for example, tapped) by a management member to add, delete, or change a member.

  The detail button 203 is a button that is pressed by a member in order to view all the sharing targets registered in the bulletin board (system failure A) or register the sharing input target in the bulletin board. When the detail button 203 is pressed, the bulletin board detail screen 210 in FIG. 2B is displayed.

  The summary browsing button 204 is a button pressed by a member to browse a summary registered on the bulletin board (system failure A). When the summary browsing button 204 is pressed, the bulletin board summary screen 310 of FIG. 3B is displayed.

  FIG. 2B shows an example of the bulletin board detail screen 210.

  The bulletin board detail screen 210 is displayed on the secure browser 221 by the information sharing support server 70 (information sharing support program 731) based on the detailed data 734 (see FIG. 1) of the bulletin board corresponding to this screen. The bulletin board detail screen 210 includes a summary browsing button 211, a bulletin board main field 293, a shared input target field 292, and a registration button 219.

  The summary browsing button 211 is a button pressed by a member to browse a summary registered on the bulletin board (system failure A). When the summary browsing button 211 is pressed, the bulletin board summary screen 310 of FIG. 3B is displayed.

  In the bulletin board main field 293, a list of all sharing targets registered in the bulletin board is displayed. The secure browser 221 can scroll the list displayed in the bulletin board main field 293 up and down in response to a scroll operation (for example, up and down swipe) performed on the field 293. Information sharing support based on the detailed data 734 (see FIG. 1) that when this member (user) first displayed the sharing target on the field 293, the sharing target was first viewed (displayed) for this member. The number of viewers (number managed in the detailed data 734 (see FIG. 1)) for the sharing target detected by the server 70 (information sharing support program 731) is the information sharing support server 70 (information sharing support program 731). ) And the member's name is associated as the viewer. The name of the member is known after user authentication. Each sharing target is displayed in a balloon, and the number of viewers in the balloon is incremented with the above-described increment.

  Take one speech bubble 214 as an example. In the balloon 214, the ID “2” (for example, serial number) of the sharing target, the shared input target “Check the cause” (character string) in the sharing target, and the member who has input (registered) the shared input target Name “K.Ohhara”, shared input registration time “10/18/13 15:37:30”, a check mark indicating that there are viewers and the number of viewers “3” 215 are displayed. The The maximum number of viewers is the number obtained by subtracting 1 from the number of members on the bulletin board. The secure browser 221 notifies the information sharing support server 70 of a predetermined operation (request) performed by the user with respect to the check mark 215 in the balloon, and in response thereto, the information sharing support server 70 The secure browser 221 notifies the secure browser 221 of the names of all the notified viewers on the screen 210 by, for example, pop-up.

  Take another balloon 216 as an example. In this balloon 216, there is a code string “3.>” before the shared input target “Please recover.” This means that the shared input target (message) following “3.>” is a reply to the shared target with the shared target ID “3”. In other words, the information sharing support server 70 provides a function that allows a member to register a reply to a sharing target desired by a user on a bulletin board.

  The shared input target field 292 is a field (column) in which a shared input target is input. When a shared input target is input to the shared input target field 292 and the registration button 219 is pressed (for example, tapped), the shared input target is transferred to the information sharing support server 70 (information sharing support program 731) by the secure browser 221. The information sharing support server 70 (information sharing support program 731) transmits the shared input target and related information thereof to the detailed data 734 (see FIG. 1) corresponding to the bulletin board, and the sharing. A new balloon including the target is displayed on the bulletin board main field 293 by the information sharing support server 70 (information sharing support program 731). When a specific sharing target balloon is pressed (for example, when tapped) (or manually input), a code string “3.>” including the sharing target ID is displayed in the sharing input target field 292. The shared input target input in the state is registered as a reply to the specific shared target.

  A management member (other members may be added in addition to the management member) can register the summary to be shared displayed on the bulletin board detail screen 210.

  Specifically, for example, as shown in FIG. 3A, the management member performs a predetermined operation (for example, lengthing the first character of the desired character string) on the shared input target part (desired character string) to be registered as a summary. When the user presses and then performs an operation of tracing the character string to the end character of the character string in a pressed state), the secure browser 221 highlights the shared input target portion (for example, underline display). According to the example of FIG. 3A, three shared input target portions 301 </ b> A to 301 </ b> C are set in the secure browser 221 as summaries.

  When the management member presses the registration button 219, the shared input target portions 301A to 301C are registered as summaries. Specifically, for example, the secure browser 221 transmits a summary registration request for the shared input target portions 301A to 301C to the information sharing support server 70 (information sharing support program 731), and the information sharing support server 70 (information sharing support). The support program 731) includes, for each of the shared input target portions 301A to 301C, the shared input target portion and the ID of the shared target including the shared input target portion in the summary data 735 (see FIG. 1) of the bulletin board. .

  FIG. 3B shows an example of the bulletin board summary screen.

  The bulletin board summary screen 310 is displayed on the secure browser 221 by the information sharing support server 70 (information sharing support program 731) based on the summary data 735 (see FIG. 1) of the bulletin board corresponding to this screen. The bulletin board summary screen 310 has a detail button 311 and a summary main field 313.

  The detail button 311 is a button that is pressed to view all the sharing targets registered in the bulletin board (system failure A) or register the sharing input target in the bulletin board. When the detail button 311 is pressed, the bulletin board detail screen 210 of FIG. 2B is displayed.

  The summary main field 313 displays a list of all the summaries (parts to be shared) registered on the bulletin board. The secure browser 221 can scroll the list displayed in the summary main field 313 up and down in response to a scroll operation (for example, up and down swipe) performed on the field 313. Each summary is displayed in a balloon.

  Take one speech bubble 321A as an example. The balloon 321A corresponds to the shared input target portion 301A designated as the summary in FIG. 3A. That is, in the balloon 321A, the summary “Servers A and B are down” and the related information of the sharing target including the summary (refer to the detailed data 734 using the sharing target ID associated with the summary as a key). Related information), that is, the sharing target ID “1”, the name “Wataru Yamaguchi” of the member who entered (registered) the shared input target including the summary, and the registration time “10 / 18/13 15:35:26 "and the number of viewers for the shared input target" 3 "are displayed.

  Each member of the bulletin board looks at the bulletin board summary screen 310, as compared to viewing the bulletin board detail screen 210. The summary of a plurality of sharing targets registered on the bulletin board (for example, what kind of failure occurs and how it is recovered) Quickly). For this reason, convenience is high.

  Information sharing is generally performed using APP as in LINE (registered trademark), but information input and viewed using APP remains in the smartphone. However, in this embodiment, the secure browser 221 is used for information sharing. As a result, the information on the browser screen (for example, the input sharing input target and the browsing sharing target) does not remain in the smartphone 20, and security is improved compared to information sharing using APP.

  In the information sharing using APP, when information is newly added, the addition of information is notified to the APP by push, but in this embodiment, information sharing is performed using the secure browser 221 and the smartphone Since there is a sharing target in the server 70 instead of 20, such a push notification is usually not possible.

  However, in this embodiment, in order to avoid such a problem, a write notification APP 222 for receiving a push notification is prepared and installed in the smartphone 20. Thereby, it is possible to avoid a decrease in convenience while realizing an improvement in security.

  In the present embodiment, at least the information sharing support server 70 among the secure gateway 50 and the information sharing support server 70 is compatible with a multi-browser. In this embodiment, since the server 70 is basically accessed only from a browser (for example, a Web browser), any terminal that can install the browser is not limited to the smartphone 20, but other types of user terminals as shown in FIG. For example, information can be shared using the server 70 in a mobile type (for example, tablet type) or desktop type personal computer, a tablet type smart device, or the like. That is, the information can be shared not only with the mobile terminal but also with other types of terminals. Note that the secure browser 221 may not be installed (installed) in all types of terminals, and may be installed at least in a mobile terminal such as the smartphone 20, for example. That is, at least one or more browsers (typically Web browsers) included in the mobile terminal include a secure browser. At least the mobile terminal may be lost, but since the information is shared by the secure browser in the mobile terminal, the risk of leakage of the sharing target can be reduced even if it is lost. The browser installed in each terminal may be only a secure browser, or a browser other than the secure browser may be installed in addition to the secure browser. Further, the write notification APP 222 may not be mounted on all types of terminals, and may be mounted at least on a mobile terminal such as the smartphone 20, for example. As will be described later, the write notification APP 222 receives a notification from the server 70 that activates the secure browser 221 and activates the secure browser 221 using the notification. Specifically, for example, the notification includes a link (for example, a URL (Uniform Resource Locator) scheme) in which an activation target (for example, an APP to be activated) is specified, and is specified by the link. The activated target is the secure browser 221. The write notification APP 222 uses the link described in the received notification to start the secure browser 221 specified for the link. A mobile terminal such as the smartphone 20 has a plurality of APPs including a secure browser 221 and a write notification APP222. In this embodiment, a notification from the server 70 (for example, a link described in the notification) The sharing target itself (or information directly connected to the sharing target) is not included, and the secure browser 221 is designated as the activation target for the link. Therefore, the sharing target does not leak from the notification, and even if the mobile terminal having the write notification APP 222 has other types of browsers in addition to the secure browser 221, the write notification APP 222 causes the browser to The secure browser 221 is activated. Thereby, more secure information sharing can be realized. In the present embodiment, the secure browser 221 and the write notification APP 222 are independent APPs. However, the secure browser 221 and the push notification reception function as the write notification APP are functions of the secure browser 221 and the write notification APP. Both may be included in one APP. The push notification reception function is a function that can receive a notification transmitted from the server 70 and, when receiving the notification, notifies that the notification has been received by display or voice.

  In the present embodiment, the service provided by the information sharing support server 70 is not a shared service. That is, if the browser, gateway 50, and server 70 can be prepared, the service can be used independently (stand-alone) for each environment. For example, the information sharing support system of the present embodiment can be constructed for each company, and the system can be an independent environment for each company.

  For example, when a shared input target is registered on a bulletin board by a certain member (referred to as “registered member” in this paragraph), the information sharing support server 70 (information sharing support program 731) manages the management data 732 corresponding to the bulletin board. Based on (see FIG. 1), all members other than the registered members among the plurality of members belonging to the bulletin board are specified. Then, the information sharing support server 70 (information sharing support program 731) activates the secure browser 221 to the write notification APP 222 of each smartphone 20 of all the specified members based on the user management data 762 (see FIG. 1). A notification to be transmitted (for example, a notification including the link specifying the secure browser 221). The notification may be transmitted every time a new sharing target is registered, or may be transmitted after a certain time has elapsed since the new sharing target has been registered. In the latter case, for example, if a new sharing target is registered and a new target is registered within a certain time, wait for a certain time again, and if a new sharing target is not registered within that time, a notification is sent. May be. In this case, one notification may describe that a plurality of sharing targets are newly registered.

  FIG. 4A shows an example of the APP list screen.

  The APP list screen 400 displays a list of installed APP icons. This list includes the icon 401 of the write notification APP 222. The icon 401 of the write notification APP 222 displays the number 402 of unread notifications among the notifications received by the write notification APP 222. This is the number of unread notifications 402 set by the write notification APP 222, and the value may be displayed directly or indirectly by the write notification APP 222 (for example, the number of unread notifications by the write notification APP 222). May be displayed to the OS (operating system) of the smartphone 20 and displayed by the OS). Further, instead of or in addition to the number of unread notifications, the number of unread sharing targets may be displayed in association with the icon 401. Specifically, the number of unread sharing targets can be specified from the unread notification.

  When the icon 401 is pressed (for example, when tapped), the write notification APP 222 is activated. The write notification APP 222 displays a list (not shown) of unread notifications. When a notification desired by the user is selected (for example, tapped) from the list, the write notification APP 222 starts the secure browser 221 in accordance with the notification (for example, the secure designated by the link described in the notification) The browser 221 is activated). When the secure browser 221 is activated, the secure browser 221 is configured to issue an access specifying a predetermined URL to the information sharing support server 70. The “predetermined URL” is a URL set in advance for the secure browser 221, and is a URL specified for access when the secure browser 221 is activated. The predetermined URL is, for example, the URL of the top page of the information sharing support server 70. The secure browser 221 displays a page according to a predetermined URL, and then accepts an operation from the user, whereby a request according to the operation (for example, a newly registered sharing target display request) is sent to the information sharing support server 70. In response to the request, the display information according to the request is transmitted to the secure browser 221, whereby, for example, the secure browser 221 displays the screen of FIG. 4B (expression information from the information sharing server 70 is displayed). Screen 410) is displayed. In the present embodiment, the “unread notification” is either a notification that has not been displayed in the unread notification list or a notification that has been displayed in the unread notification list but has not yet been selected. . In other words, an unread notification becomes a read notification by being selected from a list of unread notifications. The “display information” is at least one of information displayed by the secure browser 221 and information used to generate information displayed by the secure browser 221.

  In the present embodiment, high security is realized by using the secure browser 221. Further, high security is realized by two-step authentication, that is, device authentication in the secure gateway 50 and user authentication in the information sharing support server 70. The

  FIG. 5 shows a flow of two-step authentication according to the present embodiment.

  The secure browser 221 transmits a device authentication request to the secure gateway 50 (step 1). The authentication request includes a certificate issued at the time of device registration of the smartphone 20. The secure gateway 50 determines whether or not the certificate is correct (step 2), and notifies the secure browser 221 of the determination result (step 3). If the determination result is affirmative, device authentication is passed.

  If the secure browser 221 passes the device authentication, the secure browser 221 transmits a user authentication request (step 11), and the request is relayed to the information sharing support server 70 by the secure gateway 50 (step 12). In response to the request, the information sharing support server 70 (user authentication program 730) requests the user to input the user ID and password, and receives the ID and password from the user through the smartphone 20 in response to the request. Whether or not the ID and password are correct is determined with reference to the user management data 762 (step 13). The information sharing support server 70 (user authentication program 730) notifies the secure browser 221 of the determination result (step 14). If the determination result is affirmative, the user authentication is passed. As a result, the user can use the information sharing support service of the information sharing support server 70.

  Such two-step authentication (device authentication and user authentication) is performed, for example, every time the secure browser 221 specifies the predetermined URL, and when the two-step authentication is successful, the predetermined URL is The specified access may be permitted. Thereby, even if the smartphone 20 is lost, for example, it is possible to prevent the sharing target from being browsed by an unspecified third party who picks up the smartphone 20.

  Hereinafter, with reference to FIG. 6, one feature of the present embodiment will be summarized.

  FIG. 6 shows the flow of one process performed in this embodiment.

  A mobile terminal such as the smartphone 20 has a plurality of APPs. The plurality of APPs includes a secure browser 221 and a write notification APP 222. Instead of the secure browser 221 and the write notification APP 222, one APP including both a secure browser function that is a function as a secure browser and a push notification reception function that is a function as a write notification APP may be adopted.

  The information sharing support server 70 (for example, the information sharing support program 731), when a predetermined event occurs (for example, a new sharing target including a shared input target newly input from any terminal is newly stored in the storage resource 73. (When included in the bulletin board data unit 740), a notification (for example, specifying the secure browser 221) for starting the secure browser 221 among the plurality of APPs of the smartphone 20 is sent to the write notification APP 222 of the smartphone 20. The link (for example, a notification including the URL schema as described above) is transmitted (step 601).

  In the smartphone 20, the write notification APP 222 notifies the reception of the notification (step 602). For example, as illustrated in FIG. 4A, the write notification APP 222 displays the number of received notifications (for example, unread notifications).

  When the write notification APP 222 receives a predetermined user operation (for example, designation of notification, tap of an icon of the write notification APP 222, etc.), the received notification (for example, a link included in the notification) is used to generate a plurality of APPs. The secure browser 221 is activated (step 603). As a result, the activated secure browser 221 issues access specifying a predetermined URL (step 604). At that time, the above-described two-step authentication is performed, and when the two-step authentication is successful, the access may be permitted.

  The information sharing support server 70 (for example, the information sharing support program 731) receives access specifying a predetermined URL, and transmits display information for a page according to the predetermined URL to the secure browser 221 (step 605). Thereby, the secure browser 221 displays the display information for the page. This display information is temporarily stored, for example, in the storage resource 213 (for example, a cache area) of the smartphone 20, but when an event such as closing a page according to the expression information or closing the secure browser 221 occurs. Are deleted from the storage resource 213 by the secure browser 221. The same applies to information input to the screen (page) displayed by the secure browser 221 in addition to the display information.

  The secure browser 221 then receives an operation from the user, and transmits a request according to the operation (for example, a newly registered sharing target display request) to the information sharing support server 70 (step 606). In response to the request, the information sharing support server 70 (for example, the information sharing support program 731) transmits display information according to the request to the secure browser 221 (step 607). Thereby, the secure browser 221 displays the information for display (for example, as shown in FIG. 4B, the sharing target newly registered in the information sharing server 70 is displayed).

  Thus, in this embodiment, at least a mobile terminal such as the smartphone 20 shares information by the secure browser 221. For this reason, even if the mobile terminal is lost, the sharing target does not leak from the mobile terminal.

  Further, in the present embodiment, the notification transmitted by so-called push from the information sharing support server 70 includes a link, and the link includes the sharing target itself (or information directly connected to the sharing target). Is not included. For this reason, the sharing target does not leak from the unread notification held by the lost mobile terminal.

  Further, in the present embodiment, the link included in the notification transmitted by push specifies the secure browser 221 as an activation target. Therefore, secure information sharing can be maintained.

  As described above, according to the present embodiment, it is possible to thoroughly prevent the sharing target from leaking from the mobile terminal.

  As mentioned above, although one embodiment of the present invention was described, this is an illustration for explaining the present invention, and is not intended to limit the scope of the present invention only to this embodiment. The present invention can be implemented in various other forms. For example, the information sharing place is not limited to the bulletin board, but may be a virtual space or the like. The information sharing support server 70 (information sharing support program 731) may have a search function. Specifically, for example, the information sharing support server 70 (information sharing support program 731) accepts input of search conditions (for example, keywords) desired by the user on at least one of the bulletin board detail screen and the bulletin board summary screen. Alternatively, the sharing target corresponding to the search condition may be searched from the detailed data 734 or the summary data 735, and a list of found sharing targets (or summaries) may be displayed. Further, for example, the notification (push notification) for starting the secure browser function is replaced with a link specifying the secure browser function (secure browser 221), and other types of information (codes) specifying the secure browser function (secure browser 221) ).
