File access control method based on filter driving, system and filer manager

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a file access control method, system and filter manager based on filter drivers. Background technique [0002] With the popularity of computer applications, the data stored in the computer is becoming more and more important. From the confidential documents of the government and enterprises to the personal privacy of home users, there is always the risk of loss and leakage, and there are often situations where multiple people share the same computer, which further increases the insecurity of information. [0003] Windows system is the most widely used computer operating system at present, but its protection of data and division of rights are not perfect enough.

Problems solved by technology

From the confidential documents of the government and enterprises to the personal privacy of home users, there is always the risk of loss and leakage, and there are often situations where multiple people share the same computer, which increases the insecurity of information.

[0003] Windows system is currently the most widely used computer operating system, but its protection of data and division of permissions are not perfect enough. Once users log into the system, they can usually access any file in the computer, which is very unsafe.

Although Windows itself provides the NTFS file format, user access rights can be set, but this method is complicated to operate, and once the system fails to log in successfully, even if the file itself is not damaged, the file may be locked and cannot be read and restored. , causing heavy losses

[0004] Most of the file access control software currently on the market is implemented through HookAPI. The advantage of this method is that it is simple to implement. The disadvantage is that it is not tightly integrated with the operating system, cannot filter all file operations, is easy to be cracked, and is also easy to interact with other programs. Conflicts, and also have a certain impact on the efficiency of the system
