Abstract

The invention discloses a method and a system for protecting file integrity. The system comprises a current folder module, a backup folder module, a file update detecting module and a file integrity testing module. A file stored in the current folder module further comprises a file integrity information unit and a file information unit. A file stored in the backup folder module further comprises a file integrity information unit and a file information unit. The technical schemes adopting the method and the system can guarantee integrity of a system key file, so that operation abnormity of a system application program due to damages of the file is avoided, reliability of a file accessed by a user application program is guaranteed, and stability and safety of a whole application system are greatly improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and system for file integrity protection. Background technique [0002] At present, embedded operating systems are widely used in electronic information, communication and other industries, and many embedded operating systems provide support for file systems. The support for the file system provided by the operating system can greatly simplify and facilitate the development of application programs. In practical applications, program developers are accustomed to storing key data and system-related application information in various formats of files in program applications. [0003] In the application of embedded operating system, the damage of key files often leads to the failure of some important functions of the system, and even affects the normal operation of the entire system. It is particularly important to ensure the integrity of key system files and d...
