A second object of the present invention is to provide a confidential data security protection device, which provides a self-protection security structure including a confidential data processor. If the confidential data processor is improperly damaged by external forces, the confidential information can be self-contained in a short time. Clear, confidential information will not be stolen.

The confidential data security device that achieves the above object of the invention utilizes a fine signal loop of the multilayer printed circuit to prevent any cutting and grinding damage tool from opening the shell to steal confidential information. This device contains:

1. Anti-tampering safety protection circuit circuit signal assembly, for macro switch array, touch conductive film, and fine winding signal circuit, these three signals can be used to clear confidential data, and tamper-proof safety circuit circuit The signal can form a fine winding signal circuit loop at the fixed hole position of the casing and the circuit board, the protection system is pulled out and damaged, and the tamper-proof controller is provided.

2. Confidential Data Memory components are primarily responsible for storing confidential information.

3. Tamper Proof controller, providing a way to replace the traditional micro-motion Off, as the hardware design of the sensor that activates the tamper-proof function, it is responsible for receiving the confidential data control signal from the macro switch array, the touch conductive film, and the fine-wound signal circuit, and starting the confidential data clearing process.
