Problems solved by technology

[0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: the existing HDD-based data security protection scheme mainly manages the access authority of the data storage device. It is impossible to judge whether the storage device is in a legal use state, and the existing storage device does not provide self-destruct function, it is only protected by password or other methods, and it may be cracked by violence, which will lead to the leakage of confidential data and cause serious consequences

Embodiment approach

[0031] One is that the authentication can be performed by the IP address segment or MAC address segment of the computer that is allowed to access the SSD preset in step S11, and the application system will request the IP address segment or MAC address segment of the computer that uses the SSD to establish with step S11 If the IP address or MAC address of the computer is in the address database, it means that the SSD is allowed to be used by the computer, and the authentication is successful, and then proceed to step S14, otherwise it means that the SSD is not allowed to be used by the computer , the authentication was unsuccessful.

[0032] The other is to ask the computer user who requests to use the SSD to input the user name and password. If the user name and password match, the authentication is successful and step S14 is performed, otherwise the authentication is unsuccessful.

[0033] The other is to compare and search the fingerprint information of the computer user req...

Abstract

The embodiment of the invention provides a data security protection method which comprises the following steps: access right authentification is carried out on access users according to the confidential conditions preset in a solid state disk; if the authentification is not passed, data self-destruction is carried out according to a data self-destruction method preset in the solid state disk. The embodiment of the invention also provides a data security protection device. When the solid state disk is in the state of illegal possession or use, the data self-destruction function can be realized by self-operation of the device, thus better ensuring the data security and preventing confidential data from illegal disclosure.

Description

technical field [0001] The invention relates to the technical field of storage security, in particular to a data security protection method and device. Background technique [0002] SSD (Solid State Disk / Drive), also known as solid state disk or electronic disk, as a new storage medium, based on Nand Flash, simulates the basic access mode of dynamic random access memory, and can achieve high-speed data random access transmission. The traditional mechanical hard disk HDD (Hard Disk Drive) uses magnetic media as the storage medium, and data is stored on the magnetic tracks of the hard disk. Not only that, SSD also has its own advantages in data security protection compared to traditional mechanical hard disk HDD. [0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: the existing HDD-based data security protection scheme mainly manages the access authority of the data storage device. I...
