Non-volatile memory-based data self-destruction method and system

Abstract

The invention discloses a non-volatile memory-based data self-destruction method and system. The method is characterized in that different storage areas are divided in a storage module, and differentstorage time is set; and data is self-destroyed in a specific storage time in the different storage areas, or a read-write mode is dynamically selected for each storage area to perform different read-write operations, and self-destruction time is set by a user. The system comprises a storage data interface, a non-volatile memory controller, the storage areas and a storage data conversion center; and a storage area analysis module and a storage mode control module are arranged in the non-volatile memory controller. Based on the physical properties of a non-volatile memory, the self-destructionof the data in a fixed time is achieved through the process and the physical properties of the memory; by worsening the holding property of a device, the self-destruction of the data in the fixed timeis realized; the data self-destruction at different time can be realized according to the requirements of the user; and the convenience of data storage is realized.

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.
