Description

  The present invention relates to a peep prevention system, a method and a program for preventing peep of an administrator computer or the like.

  In recent years, in offices and school education sites, a system has been provided that enables browsing and monitoring of information related to the operation of the viewed computer from the viewing computer. Administrators such as supervisors, computer administrators, and teachers log in to the viewing computer. The operation information of the computer to be browsed can be browsed by the viewing authority (see, for example, the system disclosed in Non-Patent Document 1).

  By the way, when an administrator uses these browsing computers to browse the administrator screen, secret information or privacy information leaks to the third party when the third party peeks from behind. There is. In such a system, it is only necessary for the administrator who is browsing to be careful about peeping around. However, in many systems, the administrator makes the computer recognize the browsing authority when logging in. An appropriate computer can function as a browsing computer, and depending on the installation environment of the browsing computer, the possibility of information leakage due to the above-mentioned peeping may be high. There are dangerous situations that cannot be ignored.

  Conventional techniques for preventing such peeping on a computer screen include, for example, display means for displaying an electronic document, imaging means for imaging an operator side, and extracting a human face area from the obtained captured image. A face area extracting means and a display control means for concealing the electronic document displayed by the display means in accordance with the number of extracted face areas, and display when two or more human faces are extracted. An electronic document browsing device that conceals an electronic document displayed by a control unit has been proposed (see, for example, Patent Document 1). According to this, when a third party is peeping, information is concealed, and leakage of confidential information and information related to privacy can be surely prevented.

  However, since such conventional peeping prevention technology automatically conceals information if there are two or more viewers, for example, a plurality of administrators having equivalent browsing authority are the same computer It is not applicable to meetings, meetings, consultations, etc. while looking at the administrator screen in the same way. Similarly, an administrator who has the same authority or higher authority as the administrator who is browsing Even if you look into them for viewing, the information is unnecessarily concealed, making it difficult to supervise managers.

This is a system that is concealed, and is a system that prevents secret / important information and privacy information from leaking out from a peep by a person without viewing authority. In each of the following embodiments, an example in which the browsing target is the operation information of the computer to be browsed will be described. However, the present invention is not limited to this and can be applied to various types of information.

  First, a first embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the peeping prevention system S <b> 1 according to the present embodiment includes a browsing computer 1, a server computer 2 connected to the computer via a network, and a plurality of servers connected to the server computer 2. The browsing computer (client computer) 3 includes a server computer having an authority information storage unit, and transmits the face information imaged and acquired by the browsing computer to the server computer. This is an example in which the authority is grasped and a control signal for concealing the display form is transmitted to the viewing computer as necessary. Note that a plurality of browsing computers 1 may be connected to the server computer 2. The browsed computer 3 includes a client computer and a browsing computer 1.

  Operation information by a person is transmitted to the server computer 2 via the communication network N from the browsing computer 1 and the computer to be browsed (client computer) 3... And stored in the storage means 21 of the server computer 2. Yes. The person (administrator) of the viewing computer 1 displays and browses the operation information (operation log and operation screen) of the viewed computer stored and managed in the server computer 2 according to the viewing authority of the administrator. The browsing computer 1 is not necessarily a fixed computer, and any one of a plurality of computers that are communicatively connected to the server computer 2 can function as a browsing computer.

A computer device to which an imaging camera 13 for imaging and a communication control unit 14 are connected can be used, and the processing device 10 is mainly composed of a CPU such as a microprocessor and has a storage unit including a RAM and a ROM (not shown). Programs and processing data for defining the procedure of various processing operations are stored. For example, a general-purpose USB camera can be used, and the imaging camera 13 can be used, for example, at the top of the display so that the face of the person who is looking at the display 12 or the person who is peeping can be imaged. It may be installed to image the viewer side, but as another example, it is preferable to use a surrounding surveillance camera.

  The processing device 10 functionally receives from the server computer 2 a face information acquisition processing unit 10 a that acquires face information from the imaging camera 13, a face information transmission processing unit 10 b that transmits the acquired face information to the server computer 2. When the face information is acquired based on the control command, the display means is configured to conceal part or all of the information that is not allowed based on the viewing authority of the person among the information displayed in advance. And at least a display form control unit 10c for controlling the functions, and these functions are realized by the program.

  The face information acquisition processing unit 10a extracts a face area of a person from the captured image obtained by the imaging camera 13 by face recognition processing, and acquires face information. Known recognition techniques can be widely applied to the face recognition processing. When looking into the display, the face is usually the front face. Therefore, when the face area is extracted, only the front face is extracted. It is possible to eliminate the case where the user is not looking at the screen because he / she is facing, and the person who is peeping more accurately can be specified. In addition, if the time when the face area is extracted is determined and the face information is set to be acquired only when the time is longer than the predetermined time, for example, a person may have passed through the display momentarily It is possible to efficiently perform concealment control in cases where there is a high risk of peeping.

  When face information is acquired, the display form control unit 10c conceals a part or all of information other than information permitted to be browsed based on the viewing authority of the person among the information displayed in advance. The display means is controlled so that As a control method for concealing part or all of the information, various methods such as lowering the luminance of information to be concealed in steps or making it invisible can be employed. Further, it may be displayed completely black, mosaiced, or invisible.

  As shown in FIG. 3, the server computer 2 can use a computer device to which a storage unit 21 and a communication control unit 22 are connected with a processing device 20 as the center. The processing device 20 is mainly a CPU such as a microprocessor. And a program and processing data for defining various processing operation procedures. Functionally, the processing device 20 has a browsing authority information acquisition processing unit 20a that acquires the browsing authority of the person from the authority information storage unit 21a based on the face information received from the browsing computer 1, and the received face information. A control command generation processing unit 20b that generates a control command for controlling the display means, and a control command transmission processing unit 20c that transmits the generated control command to the viewing computer 1, and includes these functions. Is realized by the above program.

  Further, the browsing authority information acquisition processing unit 20a extracts the browsing authority of the person from the authority information storage unit 21a based on the face information acquired by the face information acquisition processing unit 10a.

  The storage means 21 of the server computer 2 is provided with an authority information storage unit 21a for storing and managing a person's face information and the information browsing authority of the person. The operation information of the viewing computer 1 and the computer 3 to be browsed is recorded, and the operation information can be acquired from the viewing computer 1.

  The operation information includes various information related to the computer operation by the user on the viewed computer, and is displayed on the computer screen as well as various operation logs such as access to the Internet site, mail transmission, application use, etc. What recorded screen information, operation history information of a pointing device such as a mouse, operation history information of a keyboard, sound output information acquired from an audio driver or an audio device, and the like may be set as necessary.

If one of these is selected, the top of the selected client computer is displayed as shown in FIG. The front window screen is enlarged. In this example, a real-time window screen is displayed, but recorded window screen information can also be reproduced and displayed.

  Depending on the viewing authority, the range of computers that can view the operation information of the browsed computer and the operation content are set to be different. The range of computers refers to setting a group of computers that can be browsed, for example, as shown in FIG. 7B, computers other than the computer in the group (belonging) of “35008” can be browsed according to authority. The operation content refers to setting the operation content of the operation information of each computer according to the authority, for example, that only the use of a specific application can be viewed.

  Hereinafter, each procedure in the peep prevention system of the first embodiment will be described based on the flowchart of FIG.

  The face information acquisition processing unit 10a extracts a face area of a person from the captured image obtained by the imaging camera 13, acquires face information (facial feature information) (S1), and acquires the face information transmission processing unit 10b. The face information is transmitted to the server computer 2 (S2). The browsing authority information acquisition processing unit 20a of the server computer 2 acquires the browsing authority of the person from the authority information storage unit 21a based on the received face information (facial feature information) (S3).

  When the face information is acquired, the control command generation processing unit 20b specifies information other than information permitted to be browsed based on the viewing authority of the person among the information displayed in advance (S4). ), And generates a control command for changing the display of the administrator screen so that part or all of the information is concealed (S5), and the control command transmission processing unit 20c transmits the control command to the viewing computer 1 To do. (S6). In the browsing computer 1 that has received this control command, the display mode control unit 10c controls the display mode of the display so as to hide part or all of the information based on the control command (S7).

  For example, when the viewing authority for the persons A to D as shown in FIG. 6 is set and the face information of the persons A and B is acquired as shown in FIG. In the figure, the authority screens are compared, and the operation screen information of “XX35008...” Belonging to the belonging group “35008” is displayed as information other than information permitted to be browsed, that is, information not permitted to the person B As shown in (b), it is concealed, here, the brightness is lowered and the display is made dark. Specifically, the comparison of the browsing authority is based on the browsing authority of the person A, and the group in which the person A does not have the browsing authority is sequentially extracted from the groups in which the person A has the browsing authority. What is necessary is just to specify as information which should be concealed. In this example, the case where the face information of two or more persons is acquired is described, but the same applies to the case where the face information of only one person is acquired. That is, when only the face information of the person A is acquired, information other than information permitted to be browsed, that is, information not permitted to the person A may be concealed based on the viewing authority of the person A.

  Further, as shown in FIG. 8A, when the face information of the person C is acquired, the viewing authority of the persons A, B, and C is compared, and information other than the information permitted to be browsed, that is, the person B is compared. In addition to the unacceptable “XX35008...”, The display of the operation screen information of “XX35007...” Not permitted by the person C is further concealed as shown in FIG. . As shown in FIG. 9A, when the face information of the person D is further acquired, information other than information that is commonly permitted for the viewing authority of each person, that is, “OO35007... In addition to “XX35008...”, Information of “XX35009...” And “XX35011.

  In addition, it is preferable to grasp the viewing authority of these persons whenever the face information captured by the imaging camera 13 is changed. When the person who has been peeping on the way leaves, the viewing authority is again displayed. The acquisition and display control is performed, and depending on the authority of the person who has left, the hidden information is displayed again as usual. In this example, the browsing authority of the persons B and C is not high or low, but in the case where the upper browsing authority includes all the lower browsing authorities, the display mode is the lowest browsing among a plurality of persons. Other information may be concealed according to authority. When a person who does not have browsing authority (all authority is X) is browsing, the entire management screen is concealed.

  As another example, an emergency warning mail request is sent from the browsing computer 1 to a management computer such as a server simultaneously with the control of concealment or after the control, so that all browsing computers are notified of the risk of peeping at the computer. It is also preferable to configure. It is also a preferred embodiment to record the viewer who is reflected in the imaging camera simultaneously with the concealment control or after the control. By recording the concealment operation, it is possible to determine who is browsing (looking into) which terminal. In addition to knowing the tendency of terminals that are easy to browse, it also shows the tendency of people who browse (peek).

  Next, a peep prevention system S2 according to the second embodiment of the present invention will be described based on FIGS. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIGS. 11 and 12, the peeping prevention system S <b> 2 according to the present embodiment includes a browsing computer 1, and the browsing computer 1 includes a single computer or a plurality of computers. In addition, it is possible to use a computer device to which a storage unit 11, a display 12 as a display unit that displays information in a viewable manner, and an imaging camera 13 as an imaging unit that captures a viewable range can be used.
