Data security protection device

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
