Sensitive data protection system

Abstract

The invention discloses a sensitive data protection system. The sensitive data protection system comprises a protection shell, a signal monitoring module, a controller, a power module and an interface module, wherein the protection shell can convert mechanical deformation of the protection shell into corresponding electric signals by self. When no external force is applied, the protection shell can generate an initial electric signal value received and recorded by a controller. When the shell is damaged by mechanical deformation, the electric signal generated by the shell is changed, and the controller detects a change value and controls a storage module to remove sensitive data. Compared with the prior art, the sensitive data protection system has the characteristics that the security detection is carried out by utilizing the electric signal generated by any mechanical deformation of the shell, the defect that gaps among densely-distributed monitoring lines are utilized for drilling to steal the sensitive data in the prior art can be overcome, so that the data security is better.

Description

technical field [0001] The invention relates to a sensitive data protection system. Background technique [0002] The security protection of sensitive data in computer systems has always been a research topic that has attracted much attention. For the sensitive data stored in the computer system, it is usually protected based on the management method of software, and it is determined whether to allow the protected sensitive data to be read by setting the authority of the visitor. [0003] The software-based management method protects sensitive data, which can prevent all unauthorized users from reading sensitive data in form. However, other people can still use the method of line monitoring to obtain sensitive data, and its security cannot be guaranteed. Although some people install and store protection management software and sensitive data on the same chip to prevent others from illegally obtaining sensitive data through line monitoring, the cost is too high, and it cann...

Problems solved by technology

It can effectively prevent data theft by drilling holes in a certain procedure. However, when the drilling holes are smaller than the distance between the lines, the detection circuit cannot detect the drilling holes, and the self-destruct circuit will not be triggered to destroy the data by itself, and the sensitive data will be destroyed.
