Embodiment Construction

[0020] As shown in Figure 1, the software integrity protection method consists of multiple protection function modules, and implements integrity protection for the protected software according to the protection strategy. The system sets up a version backup library in a safe location, such as mobile storage or a remote server, to save a basic version and several sub-version backups of the protected software. Based on this basic version, users can define several sub-versions according to application needs. A subversion corresponds to a protection policy. For sub-versions, the protection policy and file backups of sub-version increments are saved in the repository. Runtime monitoring protection can be implemented for the software specific sub-version protection policy. When the integrity of the software is damaged due to various reasons, the specified sub-version can be used for software recovery.

[0021] There are three types of file protection methods: precise, rough, and v...

Abstract

The invention relates to a method to protect the integrity of software based on the incremental backups of version, mainly comprising a plurality of procedures: (1) the definition of protection strategies on software version; (2) the initialization of basic software version; (3) the saving of software sub-version; (4) the surveillance and protection of software operation; (5) the recovery of software sub-version. Through the definition of the incremental backups of the basic version and subversion, the invention can adopt various protection methods to introduce purifying directory for the purpose of purifying the possible implanted files outside of the system according to the difference of the file functions and working modes. The invention has an advantage that the invention can not only protect the integrity of software system but also provide renewal function for software version.

Description

technical field [0001] The invention relates to a computer host system, in particular to a version integrity protection method for safely backing up, monitoring and restoring software in an information system. Background technique [0002] Due to viruses, attacks or operational errors, the software in the information system may cause the integrity of the software program and data to be damaged, thereby making the system unable to work normally. Restoration and restoration of software is a common method, but it takes a lot of time and effort. In addition, software upgrades or updates occur frequently. The integrity protection and version update of the software can repair the damaged system in time, keep the data continuously effective, and improve the availability of the system. Software integrity protection methods can be widely used in the design, development, use and maintenance of important information systems in the fields of politics, national defense, commerce, cultu...
