Abstract

PURPOSE:To obtain a terminal equipment in which the security of display information can be secured by providing a keyboard provided with a personal identification number storage mechanism and a prescribed key input mechanism, and a security mechanism possible to interrupt and continue work. CONSTITUTION:A terminal user starts up the security mechanism 5 by depressing a security key 4 when separating from a seat. Security firmware makes a display mechanism 1 display the input request picture of a personal identification number. When the user inputs the personal identification number, the mechanism 5 stores the personal identification number in a personal identification number storage mechanism 6, and issues an instruction to erase the picture in working and to display absence to the mechanism 1. When the user comes back to the seat, the mechanism 5 is started up by depressing the key 4. The mechanism 5 makes the mechanism 1 display the input request picture of the personal identification number. When the user inputs the personal identification number, the mechanism 5 compares it with the personal identification number stored in the mechanism 6, and when they coincide, the work can be restarted by displaying a working picture, and when noncoincidence is obtained, the absence is displayed. In such a way, it is possible to realize the security of the display information.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a terminal device having a display screen or the like used in a computer system, and more particularly to a terminal device that makes it possible to protect the confidentiality of displayed information.

[Conventional technology]

Conventionally, this type of terminal device does not have a mechanism to protect the confidentiality of displayed information, so when leaving the user's desk, the user must finish the work before leaving the user's desk.

[Problem to be solved by the invention]

The above-mentioned conventional terminal devices do not have a function to protect the confidentiality of displayed information when the user is temporarily away from the desk, so when the user leaves the desk, the user must perform a task to interrupt the work and then leave. It was happening. Therefore, if the user neglects this task, there is a drawback that confidential information may be leaked to others.

[Means to solve the problem]

The terminal device of the present invention is a terminal device having a display screen, etc. used in a computer system, and has a PIN storage mechanism for storing a PIN number of an unuser, and a terminal device for providing instructions for inputting the PIN number. a keyboard having a key input mechanism; and an instruction to input the PIN number from the keyboard erases display information displayed on the display screen, etc., stores the PIN number in the PIN storage mechanism, and stores the PIN number in the terminal; The system includes a security protection mechanism that enables the user to stop the work on the device and re-display the display information that was displayed at the time of stopping the work by inputting the password when the work is restarted, thereby allowing the work to continue. It is characterized by being

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a configuration diagram of an embodiment of the present invention, in which 1 is a display mechanism having a display screen, 2 is a terminal control mechanism for controlling the overall functions of the terminal device, 3 is a keyboard, 4 is a security key,
5 is a security control unit, and 6 is a password storage mechanism.

When the unused user wants to leave his/her seat, he or she presses the security key 3 to activate the security mechanism 5 in the terminal. The security firmware causes the display mechanism 1 to display a screen requesting input of a password. When an unused user enters a PIN number, the security mechanism stores the input PIN number in the PIN storage mechanism 6, and instructs the display mechanism 1 to erase the screen in progress and display ``Away''. I do.

When the non-user returns home, he or she presses the security key 3 to activate the security mechanism 5. The security mechanism 5 causes the display device 1 to display a screen requesting input of a password. When an unused user enters a PIN number, the security mechanism checks it against the PIN stored in the PIN storage mechanism 6, and if it is the same, displays the work screen and allows the user to resume work. If so, display Away again.

〔Effect of the invention〕

As explained above, the present invention protects the confidentiality of displayed information by easily erasing the display screen when a non-user leaves the seat, and allowing only the non-user at the same end to redisplay the erased display screen. It has the effect of making it possible.

Claims (1)

[Claims] In a terminal device having a display screen, etc. used in a computer system, a keyboard having a password storage mechanism for storing a password of a terminal user and a key input mechanism for giving an instruction to input the password. ,
In response to an instruction to enter the PIN from this keyboard, the display information displayed on the display screen etc. is erased, the PIN is stored in the PIN storage mechanism, the work on the terminal device is stopped, and the work is restarted. A terminal device comprising: a security protection mechanism that allows the user to re-display the display information that was displayed when the work was stopped and continue the work by inputting the PIN number; .
