Chip self-destruction device and use method thereof

Abstract

The invention belongs to the technical field of electronic information security, and particularly relates to a chip self-destruction device and a using method thereof.The device comprises a pressure generation mechanism, a piezoelectric ceramic mechanism, a voltage detection circuit, a charge absorption circuit and a chip with a physical self-destruction circuit, and the chip is internally provided with a data storage module and the physical self-destruction circuit; after the physical self-destruction circuit is electrically conducted, the data storage module is physically damaged, the pressure generation mechanism abuts against and is connected to the piezoelectric ceramic mechanism, and the positive electrode of the piezoelectric ceramic mechanism is electrically connected with the input end of the voltage detection circuit and one end of the charge absorption circuit. The negative electrode of the piezoelectric ceramic mechanism is electrically connected with the other end of the charge absorption circuit and the output end of the physical self-destruction circuit, and the voltage detection circuit is electrically connected with the positive electrode of the piezoelectric ceramic mechanism and the input end of the physical self-destruction circuit and used for conducting the physical self-destruction circuit when it is detected that the high voltage exceeds a threshold value. The charge absorption circuit is used for absorbing stray current or small voltage.

Description

technical field [0001] The invention belongs to the technical field of electronic information security, and in particular relates to a chip self-destruct device and a using method thereof. Background technique [0002] With the continuous improvement of customers' requirements for product quality, the anti-counterfeiting requirements for high-quality products are getting higher and higher. Counterfeit goods are becoming more and more rampant, leading to the flood of counterfeit and shoddy goods on the market. Brand manufacturers suffer greatly and suffer heavy losses. In the social environment, how to put an end to counterfeit goods is a top priority. [0003] In view of the increasingly rampant counterfeit goods, many anti-counterfeiting companies have also launched a series of anti-counterfeiting products. For example, for middle and high-end commodities such as tobacco and alcohol, medicine, health care products, luggage, etc., anti-counterfeiting is carried out by addi...
