Abstract

A security monitor apparatus and method using a smart card are provided. The apparatus, which is connected to a system and displays a signal generated by the system, includes an interface that is used to communicate with the smart card containing personal identification information, a detector that detects a signal through the interface to determine insertion of the smart card into the monitor, and a controller that reads the personal identification information via the interface from the smart card and controls turning the display of the monitor on or off, when the insertion of the smart card is detected. The insertion of a smart card containing personal identification information into a monitor apparatus enables immediate screen protection and power savings.

Claims

1. A computer system display capable of showing a display, comprising:

an interface communicating with a smart card containing personal identification information of a card owner;

a detector detecting a signal through the interface determining insertion of the smart card into the computer system display; and

a controller reading the personal identification information via the interface from the smart card, and automatically turning the display of the computer system display on when the insertion of the smart card is detected and the personal identification information stored in the smart card is the same as the personal identification information stored in a storage unit of the computer system display and automatically turning the display of the computer system display off when presence of the smart card is not detected as inserted, wherein the controller registers personal identification information stored in the smart card, compares the registered personal identification information to personal identification information stored in the storage unit of the computer system display, and when the personal identification information stored in the smart card is the same as the personal identification information stored in the storage unit, and provides a delete button in an on screen display (OSD) format for the card owner to select and delete personal identification information from the storage unit of the computer system display.

2. The computer system display according to claim 1, wherein the controller further comprises:

a smart card controller, and

a display microcomputer.

3. The computer system display according to claim 2, wherein the smart card controller provides clock signals to the smart card via a connection terminal, and the smart card controller resets signals sent to, and signals output from, the smart card via a reset terminal.

4. The computer system display of claim 1, wherein the controller turns the display of the computer system display off when the detector does not recognize the presence of the smart card, after a predetermined time.

5. A method of turning a display of a computer system display on and off, the computer system display connected to a system, the method comprising:

registering personal identification information of a card carrier stored in a smart card into a storage unit of the computer system display;

checking the insertion of the smart card into the computer system display through a smart card interface of the computer system display;

automatically turning the display of the computer system display on when the insertion of the smart card is detected and personal identification information of a card carrier stored in the smart card is the same as the personal identification information stored in the storage unit;

automatically turning the display of the computer system display off when the presence of the smart card is not detected as inserted; and

when the personal identificaton information stored in the smart card is the same as the registered personal information stored in the storage unit of the computer system display, providing a delete button in an on screen display (OSD) format for the card owner to select and delete personal identification information from the storage unit of the computer system display.

6. A computer system display connected to a system, the computer system display comprising:

an interface allowing a signal to be input to, and output from, a smart card containing personal identification information of a card owner;

a detector detecting a signal output through the interface, and determining if the smart card is inserted into, or removed from the computer system display; and

a controller implementing an on-screen display (OSD) region on a display of the computer system display displaying registration and deletion buttons and an authentication result from checking the registered personal identification information, activation of the registration buttons storing the personal identification information of the card owner in a storage unit of the computer display system, the deletion buttons being displayed when the personal identification information of the smart card is the same as that stored in the storage unit and activation of the deletion buttons deleting the personal identification from the storage unit, and wherein the display of the computer system display is automatically turned on when insertion of the smart card is detected and the authentication result is that the personal identification information stored in the smart card is the same as the personal identification information stored in the storage unit, and wherein the display of the computer system display is automatically turned off when the authentication result is that the presence of the smart card is detected as not inserted.

7. The computer system display of claim 6, wherein the controller turns off the display of the computer system display when the detector transmits to the controller a signal indicating that the smart card is removed from the computer system display.

8. The computer system display of claim 6, wherein the computer system display displays a warning using the OSD region based upon the authentication result when the personal identification information does not relate to an authenticated user, and

the display of the computer system display turns off based upon the authentication result.

9. A method of managing information, comprising:

detecting insertion of a smart card containing personal identification information of a card owner into a computer system display apparatus by a detecting circuit, the detecting circuit being part of a computer system display that is capable of showing an on-screen display (OSD) on a display of the computer system display;

supplying power to the detected smart card through the detection circuit;

electronically reading information stored within the smart card;

electronically comparing the read information with personal identification information stored in a storage unit of the computer system display; and

when a result from comparing indicates the information stored in the storage unit is the same as the read information, automatically turning the display of the computer system display on and deleting the information in the storage unit.
