COMPUTER INFORMATION SECURITY SYSTEM AND OPERATION METHOD THEREOF

摘要

The present invention relates to a computer information security system and method, the system includes a connection device and a sensor. When the connection device plug in to the predetermined computer, the sensor and the connection device are conjoint, a first identification code can be stored to the computer through the connection device, and generated an initialization setting of the second identification code to the sensor through the connection device. Therefore, when the sensor is out of the predetermined range of the connection device, the connection device will control the computer for encoding to prevent unauthorized user to use the computer; when the sensor is located within the range of the predetermined range of the connection device, the connection device will automatically input the first identification code to the computer to enable the user to directly use the computer without inputting the first identification code to avoid the complicated procedure of inputting the first identification code when the user return to work on the computer, thus to reinforce the security to the information in the computer and to make the operation more convenient.
