A data security protection device

Abstract

The invention discloses a data safety protection device, which includes an energy storage battery, an action detection module, a power supply module and a microprocessor; the power output end of the energy storage battery is connected to the action detection module and the power supply module; When the external trigger acts, the internal switch is controlled to close, and the destruction signal and trigger signal are generated; the power supply module converts the electric energy provided by the energy storage battery into the stable working voltage required by the microprocessor after receiving the trigger signal; the microprocessor receives power Then generate a power supply self-locking command, control the power supply module to lock the current power supply state, and ensure that it continues to supply power to the microprocessor after the internal switch fails; execute the local data destruction action according to the destruction signal generated by the action detection module; The battery powers the microprocessor to execute the destruction action, and cooperates with the self-locking function of the power supply module to solve the problem of insufficient battery power at critical moments and ensure the safety protection capability of the device with high reliability and ultra-low power consumption.

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 use. If the battery power of the controller is exhausted during the process of data destruction, the destruction process will also be suspended; the above situations will cause the controller to fail to complete data destruction normally. As a result, the reliability of the protection is seriously reduced; in addition, the protection device also has the problems of relatively high power consumption and insufficient service life
