Computer information safety control system

Abstract

The invention belongs to the field of computer information security control, and more particularly relates to a computer information security control system which comprises a relay drive part, a computer network control relay, a computer power control relay, a computer power, a microprocessor and an interface conversion part; one circuit of the output port of the microprocessor is connected with a user computer by the interface conversion part; another circuit of the output port of the microprocessor is connected with the input port of the relay drive part; one circuit of the output port of the relay drive part is connected with the input port of the computer network control relay and another circuit of the output port of the relay drive part is connected with the input port of the computer power control relay; the computer power control relay is used for controlling the encryption on the secret HD of the computer; the computer network control relay is used for controlling the on-off of a computer network. The computer information security control system can effectively ensure the absolute security of the information of the user computer.

Description

technical field [0001] The invention belongs to the field of computer information security control, in particular to a computer information security control system. Background technique [0002] With the rapid development of computer technology and network, computer has become an indispensable tool in people's work, study and life. Similarly, the development of computer networks has also brought hidden dangers to the security of users' computer information. Network information theft, information attacks, virus transmission, etc. exist and occur all the time. In order to solve the user's computer information security problem, people have taken many measures and methods, including using a hard disk isolation card to control the work of double hard disks, two different operating systems to control the work of double hard disks, and manually controlling the two hard disks to work separately. These methods all have technical defects to varying degrees, and some cannot guarantee ...

AI Technical Summary

Problems solved by technology

These methods all have technical defects to varying degrees, some of which cannot guarantee the attack of "network hackers" on the user's hard disk information at the network end, and some need to turn off the computer to convert the hard disk to work.
