Self-destruction system for memory data

Abstract

The invention discloses a self-destruction system for memory data, which comprises a mask body, an attack preventing line, a microcontroller and a memory, wherein the mask body is used for physically sealing the memory and the microcontroller; the attack preventing line is wound on the mask body to form a serpentine routing arrangement; one end of the attack preventing line is connected with a power supply, and the other end of the attack preventing line is connected with the microcontroller and is grounded through a resistor; the microcontroller is used for detecting the level change of the other end of the attack preventing line, and erasing at least part of data stored in the memory if the level changes; and the memory is used for storing the data, connecting the microcontroller, and carrying out erasing operation on the data under the control of the microcontroller. In the self-destruction system, the microcontroller detects the level on the attack preventing line and erases the data in the memory if the level changes, so the self-destruction system can accurately learn whether the data are destructed by an external force, erase the data in the memory in time, and ensures that the important data are not divulged.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a memory data self-destruction system. Background technique [0002] With the continuous improvement of social informatization, the continuous expansion of information technology application fields and the continuous update of new network technologies, the negative impact of network and information security issues has become increasingly prominent. How to prevent the leakage, theft and Destruction has become one of the most important tasks of current information security. In addition, the need to solve security issues such as online banking, e-commerce, e-government, online securities, membership management, and digital set-top boxes is becoming more and more urgent. [0003] There are many methods of safety precautions. At present, most of them use mechanical micro switches on the circuit board to detect the outer shell of the product to protect sensitive data.

Problems solved by technology

[0003] There are many methods of safety precautions. At present, most of them use mechanical micro switches on the circuit board to detect the outer shell of the product to protect sensitive data. With this structure of self-destruct circuit, if an external intruder opens the part shell, or use a conductor to short-circuit the mechanical micro switch, then the separation of the micro switch and the shell cannot be detected by the self-destruct control circuit, thus failing to achieve the purpose of safety precautions
