Data security protection method of computer

Abstract

The invention discloses a data security protection method for a computer, which establishes a safe storage space for storing user data and controls the access authority of the safe storage space; the safe storage space is a protected partition isolated from other spaces on a hard disk , it is only allowed to be operated through the underlying unified extensible firmware interface UEFI; the method of sector-level read-write interception combined with the universal serial bus dongle USB‑KEY or software identity authentication is used to realize the encryption of hard disk data. The invention encrypts and decrypts the sent instructions and important user data information in the safe storage space of the hard disk multiple times, and issues a trusted authorization certificate between the sending and receiving parties of the instructions to perform legality authentication, effectively avoiding hacker interception software interception In addition, the present invention is easy to use and can control the reading and writing of data in the designated area, so that users can implement diversified protection schemes for different data according to their own needs.

Description

technical field [0001] The invention relates to the technical field of computer data protection, in particular to a computer data security protection method. Background technique [0002] At present, with the continuous development of computer technology, the accompanying information security issues have attracted more and more attention. As a carrier of information, computers face a variety of information security issues. For example, there are information security threats from network hacker attacks, virus intrusions, denial of service, etc.; there are also loopholes in computer management and computer use authority control. Information loss caused by insufficient strength; there are also potential safety hazards brought about by the management of storage devices for highly confidential information. [0003] With the maturity of trusted computing technology, the popularization of high-intensity biometric technology, the continuous improvement of connecting underlying hard...

Problems solved by technology

[0004] However, in the management of the storage space of the important data information of the user, the following problems still exist in the existing technology: the storage space of the important data information of the user does not have permission, so that the information in this part of the space is easily stolen and deciphered by hackers, or, Even if certain permissions are set for the storage space, when accessing this secure storage space and calling important user data information in it, it is still done through normal instructions.
