A data self-destruction method and system based on non-volatile memory

Abstract

A data self-destruction method and system based on non-volatile memory, the method is to divide different storage areas in the storage module and set different storage times; in different storage areas, the data is self-destructed within a specific storage time , or each storage area dynamically selects the read-write method, performs different read-write operations, and the user sets the self-destruct time; the system includes a storage data interface, a non-volatile memory controller, a storage area, and a storage data conversion center. The non-volatile memory controller is provided with a storage area analysis module and a storage mode control module. Based on the physical properties of the non-volatile memory, the present invention realizes the self-destruction of the data within a fixed time through the process and the physical properties of the memory itself, and realizes the self-destruction of the data within a fixed time by making the device retention characteristics worse, which can be based on the needs of users To realize the self-destruction of data at different times, and realize the convenience of data storage.

Description

technical field [0001] The invention relates to a storage method and system for data self-destruction based on physical hardware design, belonging to the technical field of data self-destruction. Background technique [0002] With the improvement of storage performance, most people focus on improving data retention characteristics and device reliability, but often ignore the requirements for information security. For some time-sensitive or cold information, the data storage can be self-destructed within a fixed period of time. Generally speaking, the self-destruction of data needs to be realized artificially through software or physical hardware. [0003] Chinese patent document CN107608915A discloses a physical self-destruction method for electronic data. A layer of slow powder is laid on the side of the electronic data storage medium that is not in contact with the circuit, and the slow powder layer is connected to an ignition device. After the slow-speed gunpowder is ig...

AI Technical Summary

Problems solved by technology

[0008] Existing data self-destruction technologies come from the outside of the memory and are implemented by software programming. The self-destruction of data cannot be realized in the hardware design of the memory itself, and it cannot be selectively kept for a fixed time.
