In addition, when an authenticated user forgets to terminate the information processing device (for example, logout operation of a personal computer) and leaves, the user is illegally used by another person who has not received user authentication. There were drawbacks.

  The present invention has been made in consideration of such conventional techniques, and an object of the present invention is to provide a system and a method for preventing the use of an information processing apparatus other than an authenticated user. It is.

  The present invention solves the above problems by the following means. That is, the invention according to claim 1 is the information processing apparatus according to the present invention, wherein the information processing apparatus comprises a contact type or non-contact type IC card, a network-connected information processing apparatus and a network camera. Includes a user password information receiving means for receiving input of user password information, a user password information transmitting means for transmitting user password information to an IC card, and an authentication result reception for receiving an authentication result from the IC card. Means, a video data transmission request means for issuing a video data transmission request to a network camera, a video data receiving means for receiving monitoring video data from the network camera, and a user using the received monitoring video data A processing device comprising user absence recognition means for creating absence recognition results and unauthorized use prevention means for prohibiting input / output operations. The IC card accepts the user password information from the storage means for storing the authentication information including the user password information and the information processing device, and matches the user password information with reference to the user password information of the authentication information. An IC card comprising: a user authenticating unit for authenticating; and an authentication result transmitting unit for transmitting an authentication result, wherein the network camera receives a video data transmission request from an information processing device. Imaging means for picking up an image and holding the image data in an image memory; video data creation means for reading out the image data held in the image memory and creating monitoring video data; and the created monitoring video A user absence monitoring system, characterized in that the camera is provided with video data transmission means for transmitting data to an information processing apparatus.

  As described above, when the user leaves the seat, the input / output operation of the information processing apparatus is prohibited, and it is impossible for another person to impersonate and use the information processing apparatus.

  The invention of claim 2 is a user absence monitoring method using authentication information including user password information, the user password information receiving step for receiving input of the user password information, and the received user password. Information is used to refer to the user password information of the authentication information, and if they match, a user authentication step to authenticate, a video data transmission request to issue a video data transmission request step, and a monitoring video data are created Video data creation step, user absence recognition step for creating a user absence recognition result using the created monitoring video data, and input / output operation if the user absence recognition result is absent. This is a user absence monitoring method characterized in that it is performed in a procedure including a prohibited unauthorized use prevention step.

  According to a third aspect of the present invention, there is provided a computer program that causes a computer to operate as the user absence monitoring system according to the first aspect by being incorporated in the computer.

  A fourth aspect of the present invention is a computer-readable recording medium on which the computer program according to the third aspect is recorded.

  According to the present invention, when the authenticated user leaves the seat, the input / output operation of the information processing apparatus is prohibited, and illegal use by impersonation of another person is impossible. Further, even if the user forgets the termination processing of the information processing apparatus (for example, logout operation of the personal computer) and leaves, it is possible to prevent unauthorized use by others.

(Example)
Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.

  FIG. 1 is a diagram illustrating an overview of a user absence monitoring system. The user absence monitoring system 1 includes an IC card 300, an information processing apparatus 100 connected to a network, and a network camera 500.

  The information processing apparatus 100 holds user password information 191.

The information processing apparatus 100 is a personal computer or a network terminal apparatus.

  FIG. 2 is a diagram for explaining the flow of processing of the user absence monitoring system 1. When trying to use the information processing apparatus 100, the user causes the IC card reader connected to the information processing apparatus 100 to read the IC card 300 held by the user, and also inputs his / her user password information. Do. Then, the information processing apparatus 100 accepts input of user password information 191 (FIG. 2 (1)).

  The information processing apparatus 100 transmits the accepted user password information 191 to the IC card 300 ((2)).

  The IC card 300 receives the user password information 191 from the information processing apparatus 100, and authenticates the user by referring to the user password information of the user authentication information 391 ((11)). The IC card 300 transmits the authentication result to the information processing apparatus 100 ((12)).

  The information processing apparatus 100 receives the authentication result from the IC card 300 (same as (13)).

  The authentication result includes a result indicating that the authentication is correctly performed and a result indicating that the authentication is not correctly performed. If the authentication is not properly performed, the user cannot log in or the like and cannot use the information processing apparatus 100. If the authentication is correctly performed, the information processing apparatus 100 issues a video data transmission request to the network camera 500 ((21)).

  The network camera 500 receives a video data transmission request from the information processing apparatus 100 ((22)). Upon receiving the video data transmission request, the network camera 500 starts photographing, creates monitoring video data, and transmits it to the information processing apparatus 100 ((23)).

  The information processing apparatus 100 receives the monitoring video data from the network camera 500 ((24)). The creation and transmission of the monitoring video data is periodically performed at a set timing. Specifically, when the network camera 500 starts shooting, it continues shooting until an instruction to end shooting is received. However, the network camera 500 creates a shot video in the format of monitoring video data for each preset time, and information It is transmitted to the processing apparatus 100.

  The information processing apparatus 100 creates a user absence recognition result using the received monitoring video data ((31)). Specifically, the video in the monitoring video data is analyzed, and “user is absent” when the target user disappears from the video, “user present” when the target user does not disappear from the video The user absence recognition result is created. A known image recognition method can be used to determine whether or not the target user has disappeared from the video. For example, the still image data constituting the video may be compared at a predetermined timing, and the user who has recognized the initial still image data may determine whether or not the user still exists in the subsequent still image data. If the user absence recognition result indicates that the user is absent, the information processing apparatus 100 prohibits input / output operations by fixing the screen or the like ((32)).

  In addition to the screen lock (fixed screen), the method of prohibiting input / output operations includes the prohibition of accepting mouse and keyboard operation information, the display of warnings on the display screen, and the information processing apparatus 100 to the network. There is a prohibition of access.
