Title: (EN) File access control method based on filter driving, system and filer manager
(ZH) 基于过滤驱动的文件访问控制方法、系统及过滤器管理器
Abstract: front page image
(EN) The invention discloses a file access control method based on filter driving, a system and a filer manager. The method comprises: adding a filter manager in an access control system; building and loading filter driving by a building and loading module of the filter manager; registering operation required to filter by the registered module of the filter manager; identifying a target file by the identification module of the filter manager; communicating the filter driving with the application program by the communication module of the filter manager; and filtering the file operation by the filtering module of the filter manager. On the premise that the invention does not need to redesign a file system and bottom layer driving, file filter driving in the Windows system intercepts and monitors file access, and the safety of file data is ensured on the bottom layer of the system.
