2 is a view illustrating an operation according to an embodiment of the ATOZ PC security system according to the present invention. Referring to this, the operation of the present invention configured as described above is as follows.

First, the RF IC card reader which operates with the power on all the time continuously emits radio waves to determine whether the RF IC card is approaching or leaving the radio range.

Then, if the user holds the RF IC card and is positioned within the radio wave range, the RF IC card reader recognizes the access of the RF IC card, reads the card authentication information (ID) of the RF IC card, and then reads the RF IC card. Card authentication is performed by comparing with a user ID registered in advance in the memory of the reader.

If the card authentication is performed, the power of the computer main body is turned on. If the card authentication is not performed, the card information is read out and the database is temporarily stored in the terminal memory unit so that the details can be viewed at any time by the user's request.

When the computer main body is turned on, the central processing unit of the main body causes the PC security system to log on. The password stored in the system memory is read from the password stored in the RF IC card according to a preset password setting level. Log on by comparing the password, which is keyed in from the input device with the password stored in the system memory.

After that, when the user moves the computer while working, the RF IC card is moved away from the radio range, the RF IC card reader detects it and sends it to the central processing unit of the main body, and the PC security system automatically protects the screen. Operate in Screen Save Mode and do not allow any keys on the keyboard to be entered.

In order to release the screen protection mode, the user must access the RF IC card (user card) applied to the system again within the radio range and receive user authentication. The user authentication for screen protection release depends on the screen protection level stored in the system. In other words, the user can be authenticated using the password inputted through the input device, or the password stored in the card is retrieved and the user is authenticated to cancel the screen save mode. This prevents unauthorized use of the computer when leaving the seat.

On the other hand, if the power off time (t) is set in the system memory, the RF IC card that logged on the system for the time (t) is continuously monitored for re-access within the radio range, and the file in operation after the time passes. To automatically save power off.

It also allows you to encrypt important files or folders during use so that you can't see the contents unless you have a designated card. When the user is in the working position, the encrypted file or folder is automatically decrypted.

The present invention constructed and operated as described above only requires the user to have a user authentication RF IC card and access / departure within a range (propagation range) to identify and secure PC security such as logon, screen protection, and file protection. By realizing it automatically, PC security can be realized easily.
