Abstract: Data file security control technology applies file filter driver technology to the process of document creation, editing and using, and uses transparent encryption and decryption to realize content protection of classified files. Combined with user initiative and passive authorization, through file filtering driver technology, API HOOK technology and permission library interaction, we can achieve online, online and off-line full, dynamic and fine grained access control. This paper provides corresponding solutions from the research of safety control technology and implementation of data files, respectively from the unified data security management, data file management, entrance door control and the use of encrypted data file encryption, audit data file dynamic authorization management, file tracing, data encryption and document traceability platform interface the research of data file. Through the research of data file security management and control technology, the effective measures to solve the file data protection in Chongqing mobile business system are found.
