User data security lock

Abstract

The invention relates to the field of computer security, and provides a user data security lock which can protect data during computer repair. The user data security lock comprises a power supply module connected with a host, a detection module, a power supply control module, a locking module and an unlocking module; the detection module is used for detecting the network security situation of the host, when it is detected that hazardous situations exist, an emergency signal can be sent to a power supply control module first, then, a locking signal is sent to a locking module, and when it is detected that the situations are safe, an unlocking module can be controlled to start and send the security signal to the power supply control module; the power supply control module is used for receiving the emergency signal and the security signal, and can control on and off of a data disk power supply in the host; the power supply control module is locked after the locking module is received, and the power supply control module cannot output a power supply signal after being locked; the unlocking module in an on state can be used for unlocking the power supply control module.

Description

technical field [0001] The invention relates to the field of computer security, in particular to a user data security lock. Background technique [0002] With the development of science and technology, computers exist in all aspects of our lives, so the importance of its security is particularly important. Only by strengthening effective security protection measures can we reduce computer security threats. The most important thing in a computer is the security of stored data. The main threats it faces include: computer viruses, illegal access, computer electromagnetic radiation, hardware damage, etc. Among them, computer viruses and illegal access have always plagued computers. user. [0003] In order to ensure the safety of data in the computer, the first thing users need to do is to install a set of anti-virus software and set up a personal firewall.

[0003] In order to ensure the safety of data in the computer, the first thing users need to do is to install a set of anti-virus software and set up a personal firewall. The effect of defense is negligible, therefore, hacker attacks should also be included in the prevention object

Once a computer is infected by a virus or maliciously attacked, the data in the computer may still be damaged during the period when the antivirus software is killing the virus or the computer is being repaired, so the data security problem needs to be solved urgently during this period.
