One or both of HDD (Hard Disk Drive) and SSD (Solid State Drive) are provided. Furthermore, a display unit such as a liquid crystal monitor for displaying an image may be provided, and an input unit such as a mouse or a touch panel for receiving input from the user may be provided.

  The user terminal 10 includes a prohibition designation unit 11, an association data storage unit 12, a target search unit 13, and an image data transmission unit 14, and the control unit, storage unit, communication unit, display unit, and input unit described above. Thus, these means are realized.

  An object is displayed on the display unit of the user terminal 10. Here, the object is a display item displayed on the user terminal 10 and includes a display target that may leak information to others. The object is, for example, a file stored in the user terminal 10, a window displayed by an application that can be activated on the user terminal 10, an icon, a desktop image, or the like.

  The prohibition designation unit 11 has a function of accepting designation from the user that the one or more objects displayed on the display unit are not visible on the support terminal 100. Here, the prohibition designation is a process designated by the user by dragging the privacy mark 16 with respect to the object as described above. In this case, the file name of the file specified by dragging by the user becomes the prohibited file name. Furthermore, the prohibition designation is processing for designating a predetermined character string (prohibited word) so that the user cannot visually recognize all files having the predetermined character string.

  When the privacy mark 16 is dragged and specified by the user by the user, the association data storage unit 12 sets the file name (prohibited file name) corresponding to the specified object to the prohibited association data. Store in the table. When the user designates a prohibited word, the association data storage unit 12 stores the prohibited word in the same table.

  The prohibited file name may be all or a part of the file name of the file stored in the user terminal 10, or may be an extension of the file.

  A prohibited word is a character that may leak user information if a file containing the prohibited word in a sentence (including figures, diagrams, etc.) is displayed on the support terminal 100. A character string that is included in the text of the file.

  The object search means 13 searches whether there is an object corresponding to a prohibited file having a prohibited file name stored in the prohibited association data table or an object having a prohibited word in the image data to be shared on the screen. It has the function to do.

  The image data transmission unit 14 has a function of transmitting image data composed of objects to the support terminal 100.

  Like the user terminal 10, the support terminal 100 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like as a control unit, and a wired / wireless compatible communication device as a communication unit. And a storage unit includes one or both of an HDD (Hard Disk Drive) and an SSD (Solid State Drive). Furthermore, a display unit such as a liquid crystal monitor for displaying an image may be provided, and an input unit such as a mouse or a touch panel for receiving input from a supporter may be provided.

  The support terminal 100 includes an image data receiving unit 101 and an image data display unit 102, and these units are realized by the above-described control unit, storage unit, communication unit, display unit, and input unit.

  The image data receiving unit 101 has a function of receiving image data from the user terminal 10, and the image data display unit 102 has a function of displaying image data received from the user terminal 10.

[Flowchart in the first process]
FIG. 5 is a flowchart of the first process executed by the user terminal 10 with the support terminal 100.

  First, the prohibition designating unit 11 of the user terminal 10 accepts the prohibition designation based on an operation from the user (step S10). As described above, the prohibition designation may be designation of a prohibited file name or designation of a prohibition word.

  Next, the designated prohibited file name or prohibited word is stored in the association data storage means 12 as a prohibited association data table (step S11). Then, in the user terminal 10, it is determined whether or not the remote support software is activated by the user (step S12).

  Remote support software is a program for sharing a screen between the user terminal 10 and the support terminal 100. Normally, by starting this remote support software, image data (including objects) of the screen of the user terminal 10 is transmitted to the support terminal 100 and displayed. The remote support software is merely an example of the present embodiment, and the screen sharing may not be used for the purpose of remote support, and may simply be software for screen sharing.

  When the user terminal 10 starts up the remote support software (step S12: “YES”), the target search unit 13 searches for a target object for which prohibition is specified (step S13). That is, the object of the prohibited file corresponding to the prohibited file name stored as the prohibited association data table is searched from the objects displayed on the screen. Next, it is searched whether the file corresponding to the object displayed on the screen includes the prohibited word stored as the prohibited association data table as a character string in the file, and the object displayed on the screen. Among these, the object corresponding to the file containing the prohibited word is searched.

  If it is determined that there is an object corresponding to the prohibited file having the prohibited file name or an object including the prohibited word in the character string in the file as a search result, limited image data excluding these objects is obtained. And transmitted to the support terminal 100 (step S14).

  Here, until the user terminal 10 activates the remote support software (step S12: “NO”), the process waits. The support terminal 100 receives the image data transmitted from the user terminal 10 by the image data receiving unit 101 and displays the image data received by the image data display unit 102.

  Therefore, the user terminal 10 accepts designation from the user operating the user terminal 10 for an object that the other supporter does not want to be visually recognized, and displays image data excluding this object on the support terminal 100. By doing so, it is possible to execute screen sharing without leaking information indicated by the object to the support terminal 100 that is a third party.

  When the user terminal 10 searches for an object corresponding to the prohibited file or an object including the prohibited word in the character string in the file in step S14, the user terminal 10 transmits limited image data excluding these objects. ing.

  Here, the user terminal 10 may transmit a flag that these objects should be removed to the support terminal 100 and may transmit the entire image data to the support terminal 100. In this case, the support terminal 100 displays image data other than the removed object on the display unit based on the flag. However, in this case, it is necessary to pay attention to information leakage caused by image data that should not be displayed on the support terminal 100 being transmitted from the user terminal 10 to the support terminal 100.

[Functional block diagram of system via information controller]
Next, a mode in which the above-described prohibition association data table is stored in the information control device by providing the information control devices 50 and 200 (gateway 50 or server 200) in the system will be described. FIG. 8 is a functional block diagram of the user terminal 10, the support terminal 100, and the information control devices 50 and 200. As the network, as described with reference to FIG. 3, the gateway 50 is connected as a terminal that connects the local network and the public line network 3. The server 200 is connected to the public line network 3.

  In the case of the present embodiment, the user terminal 10 includes a prohibition designation unit 11, an association data transmission unit 20, an object search unit 13, and an image data transmission unit 14, and the above-described control unit, storage unit, and communication unit. These means are realized by the display unit and the input unit.

  The prohibition designation means 11 has the same function as the above example, that is, has a function of accepting designation from the user that the one or more objects displayed on the display unit are not visible on the support terminal 100. . Here, the prohibition designation may be a process designated by the user by dragging the privacy mark 16 to the object as described above, or the user inputs the above prohibition word. It may be a specified process.

  When the privacy mark 16 is dragged and specified by the user by the user, the association data transmission means 20 uses the file name (prohibited file name) corresponding to the specified object as the association data. To the information control devices 50 and 200. On the other hand, when the user designates a prohibited word, the association data transmitting unit 20 transmits the prohibited word as association data to the information control devices 50 and 200.

  The object search means 13 determines whether there is an object corresponding to a prohibited file having a prohibited file name stored in the prohibited association data table or an object having a prohibited word in the image data for screen sharing. Has a search function.

  The image data transmission unit 14 has a function of transmitting image data composed of objects to the support terminal 100.

  The information control devices 50 and 200 include a central processing unit (CPU), a random access memory (RAM), a read only memory (ROM), and the like as a control unit, and a wired / wireless compatible communication device as a communication unit, and a storage. The unit includes one or both of an HDD (Hard Disk Drive) and an SSD (Solid State Drive).

  The information control devices 50 and 200 include association data reception means 201, authentication means 202, association data storage means 203, identifier search means 204, and association data transmission means 205. These means are realized by the communication unit.

  The association data receiving unit 201 has a function of receiving association data transmitted by the user terminal 10.

  The authentication unit 202 has a function of authenticating the terminal of the user terminal 10 or the user. That is, for each user who operates the user terminal 10 or the user terminal 10, a prohibited file name or a prohibited word is set, and therefore it is necessary to authenticate the user terminal 10 or the user when receiving the association data. Specifically, in the case of the user terminal 10, the authentication is performed using an identifier such as an IP (Internet Protocol) address, a MAC (Media Access Control Address) address, and a computer name. If it is a user, authentication is performed using the user ID as an identifier.

  When the association data is received from the user terminal 10, the association data storage unit 203 stores the association data in the prohibited association data table for each identifier. FIG. 7 shows a table in which a prohibition association data table is configured for each user terminal 10.

  The identifier search unit 204 has a function of searching for the corresponding prohibited association data based on the authenticated identifier after the user terminal 10 that has accessed is authenticated.

  The association data transmission unit 205 has a function of transmitting the association data corresponding to the identifier searched by the identifier search unit 204 to the accessed user terminal 10.

[Second Processing Flowchart]
FIG. 9 is a flowchart of the second process executed between the user terminal 10 and the information control devices 50 and 200.

  First, the prohibition designating unit 11 of the user terminal 10 accepts the prohibition designation based on an operation from the user (step S20). As described above, the prohibition designation may be designation of a prohibited file name or designation of a prohibition word.

  Next, the association data which is the designated prohibited file name or prohibited word is transmitted to the information control devices 50 and 200 (step S21). At this time, it is assumed that the user terminal 10 is authenticating the information control apparatuses 50 and 200 (authentication data may be transmitted together with the association data). That is, authentication is performed for each user terminal 10 or for each user by the identifier of the user terminal 10 or the user ID.

  In response, the association data receiving unit 201 of the information control devices 50 and 200 receives the association data, and the association data storage unit 203 stores it as a prohibited association data table (step S30).

  Next, in the user terminal 10, it is determined whether or not the remote support software is activated by the user (step S22).

  The remote support software is a program for sharing a screen between the user terminal 10 and the support terminal 100, and is the same as described above.

  When the user terminal 10 starts up the remote support software (step S22: “YES”), the user terminal 10 accesses the information control devices 50 and 200. In response to this, the identifier search unit 204 searches for the association data in the corresponding prohibited association data table based on the authenticated identifier (step S31). For example, in the case of the prohibited association data table of FIG. 7, if the accessed user terminal 10 is the PC 1, the prohibited file name “A file” is searched as the association data.

  Here, until the user terminal 10 activates the remote support software (step S22: “NO”), the process waits.

  Next, the association data transmission unit 205 transmits the association data corresponding to the identifier searched by the identifier search unit 204 to the accessed user terminal 10 (step S32).

  In response to this, the user terminal 10 receives the association data, and the object search unit 13 transmits the object image or prohibited word corresponding to the prohibited file having the prohibited file name among the screen image data transmitted to the support terminal 100. Is searched for in the character string in the file (step S24). If a search is made, the image data transmission means 14 transmits limited image data excluding these objects to the support terminal 100 (step S25).

  As described above, since the information control devices 50 and 200 store data related to objects that are not visible on the support terminal 100, for example, when identifying a user by a user ID, Even if the association data is set and then the screen is shared by physically different user terminals 10, the object to be made invisible cannot be recognized as long as the same user ID is authenticated. It can be made invisible.

[Transmission of image data from information controller to support terminal]
Next, a mode in which image data is transmitted from the information control devices 50 and 200 to the support terminal 100 without passing through the user terminal 10 will be described.

  FIG. 10 is a functional block diagram of the user terminal 10, the support terminal 100, and the information control devices 50 and 200 in the present embodiment. The user terminal 10, the support terminal 100, and the information control devices 50 and 200 have the same hardware configuration as described above. The support terminal 100 has the same functional configuration as that described based on FIG.

  The user terminal 10 is different from the configuration described with reference to FIG. 8 only in that the target search unit 13 is not provided and the image data transmission unit 21 is different, and the remaining configuration has the same function. That is, the user terminal 10 includes a prohibition designation unit 11, an association data transmission unit 20, and an image data transmission unit 21, and these control unit, storage unit, communication unit, display unit, and input unit perform these operations. Means are realized.

  Unlike the image data transmission unit 14, the image data transmission unit 21 has a function of transmitting image data composed of objects to the information control devices 50 and 200.

  The information control devices 50 and 200 are different from the configuration described with reference to FIG. 8 only in that they do not include the association data transmission unit 205 but include the target search unit 206, the image data reception unit 207, and the image data transmission unit 208. Is different. That is, the information control devices 50 and 200 include the association data reception unit 201, the authentication unit 202, the association data storage unit 203, the identifier search unit 204, the target search unit 206, the image data reception unit 207, and the image data transmission. These means are realized by the above-described control unit, storage unit, and communication unit.

  The object search means 206 searches whether there is an object corresponding to a prohibited file having a prohibited file name stored in the prohibited association data table or an object having a prohibited word in the image data to be shared on the screen. It has the function to do.

  The image data receiving unit 207 has a function of receiving image data from the user terminal 10, and the image data transmitting unit 208 has a function of transmitting image data to the support terminal 100.

[Flowchart of third process]
FIG. 11 is a flowchart of a third process executed between the user terminal 10 and the information control devices 50 and 200.

  First, the prohibition designating unit 11 of the user terminal 10 accepts the prohibition designation based on an operation from the user (step S40). As described above, the prohibition designation may be designation of a prohibited file name or designation of a prohibition word.

  Next, association data that is a designated prohibited file name or prohibited word is transmitted to the information control devices 50 and 200 (step S41). At this time, it is assumed that the user terminal 10 is authenticating the information control apparatuses 50 and 200 (authentication data may be transmitted together with the association data). That is, authentication is performed for each user terminal 10 or for each user by the identifier of the user terminal 10 or the user ID.

  In response, the association data receiving unit 201 of the information control devices 50 and 200 receives the association data, and the association data storage unit 203 stores it as a prohibited association data table (step S50).

  Next, in the user terminal 10, it is determined whether or not the remote support software is activated by the user (step S42).

  When the user terminal 10 starts up the remote support software (step S42: “YES”), the user terminal 10 displays the entire image data for screen sharing (including objects that should not be visible on the support terminal 100). Is transmitted to the information control devices 50 and 200 (step S43).

  In response to this, the image data receiving means 207 of the information control devices 50 and 200 receives the image data and stores it in the image data storage means 209 (not shown). Then, the identifier search unit 204 searches for the association data in the corresponding prohibited association data table based on the authenticated identifier (step S51). For example, in the case of the prohibited association data table of FIG. 7, if the accessed user terminal 10 is the PC 1, the prohibited file name “A file” is searched as the association data.

  Here, until the user terminal 10 activates the remote support software (step S42: “NO”), the process waits.

  Next, the prohibited file having the prohibited file name among the screen image data to be transmitted to the support terminal 100 based on the association data searched by the identifier searching unit 204 by the target search unit 206 of the information control devices 50 and 200. It is searched whether or not there is an object corresponding to the above or an object including the prohibited word in the character string in the file (step S52).

  If a search is made, the image data transmission unit 208 transmits limited image data excluding these objects to the support terminal 100 (step S53). If not searched, the image data transmission unit 208 transmits the entire image data for screen sharing to the support terminal 100 without performing any particular processing (step S53).

[Mode for accepting designation of object visible on second terminal]
In the above-described embodiment, when the screen is shared between the user terminal 10 and the support terminal 100, only an object that cannot be visually recognized by the support terminal 100 is accepted. However, in the initial setting, all the objects may be set to be invisible on the support terminal 100, and a mode in which cancellation of the invisible is received from the user may be adopted.

  That is, the prohibition canceling means 60 (not shown) of the user terminal 10 receives the designation by dragging the mouse or the like by the user operation with respect to the object that can be visually recognized, and stores this association data. As shown in FIG. 12, in the support terminal 100, only the control panel object 130 for which the user has canceled the prohibition designation is visible, and all other objects are invisible. In this case, the association data for canceling the prohibition may be stored in the information control devices 50 and 200 in the same manner as described above.

[Other embodiments]
As shown in FIG. 7, the prohibition association data table may specify a prohibition rule in addition to the prohibition word and the prohibition file. For example, as shown in FIG. 7, the support terminal 100 visually recognizes an object of a file that has been subjected to predetermined security processing, such as “encrypted file” or “file for which a password is set”. It may be set to be impossible. The distinction between encrypted files may be determined by the extension.

  In the above example, a blind state is provided for each object. However, for example, only some prohibited words in the object may be in a blind state. That is, when “name: Ichiro Suzuki” is present in the object, only “name: 000000” and the prohibited word “Ichiro Suzuki” may be in a blind state. In this case, for example, “Ichiro Suzuki” is registered in advance as a prohibited word.

  The means and functions described above are realized by a computer (including a CPU, an information processing apparatus, and various terminals) reading and executing a predetermined program. The application program is provided in a form recorded on a computer-readable recording medium such as a flexible disk, CD (CD-ROM, etc.), DVD (DVD-ROM, DVD-RAM, etc.), for example. In this case, the computer reads the application program from the recording medium, transfers it to the internal storage device or the external storage device, stores it, and executes it. The program may be recorded in advance in a storage device (recording medium) such as a magnetic disk, an optical disk, or a magneto-optical disk, and provided from the storage device to a computer via a communication line.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these embodiment mentioned above. The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.
