Data security protection device

Abstract

The invention discloses a data safety protection device which comprises an energy storage battery, an action detection module, a power supply module and a microprocessor. The electric energy output end of the energy storage battery is connected with the action detection module and the power supply module; the action detection module is used for controlling an internal switch to be closed when an external trigger action is detected, and generating a destruction signal and a trigger signal; the power supply module converts electric energy provided by the energy storage battery into stable working voltage required by the microprocessor after receiving the trigger signal; the microprocessor generates a power supply self-locking instruction after being powered on, and controls the power supplymodule to lock the current power supply state to ensure that the power supply module continuously supplies power to the microprocessor after the internal switch fails; a local data destruction actionis executed according to a destruction signal generated by the action detection module. The battery supplies power to the microprocessor to execute the destroying action in emergency, the self-lockingfunction of the power supply module is matched, the problem that the electric quantity of the battery is insufficient at the key moment is solved, and the high-reliability and ultra-low-power-consumption safety protection capacity of equipment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of information security, and more specifically relates to a data security protection device, which is mainly used in application scenarios with special requirements for data protection. Background technique [0002] In the field of information security, data protection is extremely important. At present, there are many physical security protection methods at the equipment level. A dedicated protective chip with high precision. These commonly used protective devices generally use batteries to power the controller that performs data destruction actions in the terminal equipment. In case of illegal disassembly, the controller cannot normally receive the power provided by the battery after the device is disassembled, which will cause the destruction process to be suspended; in addition , the battery power gradually decays during long-term use. If the battery power of the controller is exhausted during the proce...

Problems solved by technology

These commonly used protective devices generally use batteries to supply power to the controller that performs data destruction actions in the terminal equipment. Once the device is disassembled illegally, the controller cannot normally receive the power provided by the battery after the device is disassembled, which will lead to the termination of the destruction process; , the battery power gradually decays during long-term
