Abstract

The invention discloses a method for preventing hard disk data from being modified and covered. The method is characterized by comprising the steps that a Device Mapper mechanism based on a linux system kernel transmits data information to a server side through Ethernet access, and the data information is encrypted, stored and processed through the server side, wherein the specific process comprises the steps that the data information is transmitted to a central processor through the Ethernet, then temporarily stored to a double-speed synchronous dynamic random access memory and a read-only memory through the central processor, processed through the central processor and then stored into two hard disks in an mirror image mode through a disk array device, meanwhile, the hard disks are encrypted through a Cryptsetup tool, and serial numbers of the hard disks are read. According to the method, in the process of writing data in through a computer, the hard disks are encrypted through the Cryptsetup tool, the read serial numbers of the hard disks are applied to encryption secret keys, so that after the hard disks leave the computer, the content in the hard disks cannot be read or modified on other computers, and the probability that the hard disks are compiled after leaving a system is eradicated.

Description

technical field [0001] The invention relates to the technical field of computer data protection, in particular to a method for preventing hard disk data from being modified and overwritten. Background technique [0002] At present, data is usually stored using hard disks, optical disks, or electronic storage. The disadvantage of optical discs is that the amount of stored data is not large enough, and it is easy to scratch and deface, resulting in loss of important data. Ordinary hard disks are easily modified by customers, resulting in data lack of objectivity and the risk of damage. Electronic hard disks also have the same flaws. [0003] Therefore, how to provide a method for protecting hard disk data with large storage capacity, safety, non-editability and convenient retrieval is a problem urgently needed to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the present invention provides a method for protecting hard disk data w...
