Security protection system and method applied in computer system

Abstract

The present invention relates to one kind of safety protecting system and method for computer system. The safety protecting system one radio emitter assembly carried by the user to emit one specific radio signal and one radio receiver assembly connected electrically to the computer system for receiving the specific radio signal. The method includes the following steps. When the radio receiver assembly does not receive the specific radio signal, one protecting mechanism in the computer system is activated to make the computer system incapable of being used. The present invention can protect the data safety effectively.

Description

technical field [0001] The invention relates to a safety protection system and method, in particular to a safety protection system and method applied to computer systems. Background technique [0002] The use of the security protection system in the computer system is quite practical, and various methods are used to protect the data in the computer system from being easily obtained by others. In the commonly used method, the screen saver of the system can provide such security protection. After selecting the password protection option of the screen saver, as long as the operator does not use the peripheral input device within the set time, the system will enter the screen. In the protected state, and to release the screen saver state to enter the operation mode, you need to enter the account password of the original user or administrator. This is a convenient feature, and there are the following known problems in use: the computer system cannot activate the protection state...

AI Technical Summary

Problems solved by technology

This is a convenient feature, and there are the following known problems in use: the computer system cannot activate the protection state in real time, resulting in a window period of security protection between the original user leaving the seat and activating the screen protection state, or due to If the set time is too short, the system frequently activates the screen saver state, causing inconvenience to the working environment

[0003] Another commonly used technology is to add a protection lock 11,12 on the computer system 10, and the protection lock uses external devices such as a universal serial bus (USB) 13 or a printer connection port 14 (such as figure 1 As shown), to directly connect to the computer system. When the protection lock is connected to the computer system, the user can operate and use the computer normally. When the protection lock is removed, the system enters the locked protection state. This method also has Vulnerabilities in security protection caused by forgetting to activate when the original user leaves

And when the original user returns to the seat to operate the computer system, he cannot directly operate the computer system, but needs to put the protection lock back on the computer system, which makes it not very convenient to use.
