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.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Sensitive data protection system of the present invention, comprising:
Protecting sheathing: for installing sensitive data memory module, the mechanical deformation of protecting sheathing can be converted into corresponding electric signal by protecting sheathing itself;
Signal monitoring module: for the electric signal of Real-Time Monitoring protecting sheathing, and signal is transformed digital signal;
Controller: for the digital signal of Received signal strength detection module, compares with pre-recorded standard value, judges whether to exist extremely, after noting abnormalities, controls to give an order removing sensitive data by controller;
Power module: for powering to data protection system, it, by battery and/external power source, when there being external power source, charging to battery, making battery be in preparation power supply state, when outside power cut-off, battery-powered protection sensitive data;
Interface module: it is responsible for being connected with outside line, accepts the agreement instruction that outside line sends, sends controller to.
At protecting sheathing originally in time not being subject to External Force Acting; an initial value of electrical signals can be produced, be converted into by controller receiving record after digital signal, and the value of electrical signals of real-time reception afterwards; itself and this original records value compared, controller judges whether to exist extremely.Be not damaged at shell itself such as hole, the physical disturbance such as polishing time, its value of electrical signals produced can not change, this Time Controller judges that it is normal condition, when the destruction of the mechanical deformation that shell is subject to, the electric signal that shell itself produces sends out change, controller detects this abnormality changing value, makes the judgement that may be subject to data theft, and control store module removes its sensitive data.Difference with the prior art is, the value of electrical signals that the present invention utilizes any mechanical deformation of shell itself to produce is to carry out safety monitoring, can overcome to have now in technology utilizes densely covered Monitoring Line gap to carry out holing and steal the defect of sensitive data, makes the security of data better.
