Establishment method of role-oriented virtual file system

Abstract

The invention discloses an establishment method of a role-oriented virtual file system and belongs to the field of computers. The establishment method of the role-oriented virtual file system includes: establishing a corresponding role virtual file system configuration file for each role; giving a mapping relation among a virtual directory, a file and an overall situation file system in an operation system, a authority limit relation and an expanding access rule in the role virtual file system configuration file; dividing roles into basic roles and composite roles which comprising a plurality of the basic roles and the composite roles and removing a plurality of roles, and combining and removing role virtual file systems of the plurality of roles comprised in the composite roles to form role virtual file systems of the composite roles. The role-oriented establishment method of the virtual file system is capable of building any complex virtual file system in the overall situation file system of the operation system and provides a role-oriented individuation file system service for an application program in a mode of the role virtual file system.

Description

technical field [0001] The invention belongs to the computer field and mainly focuses on providing role-based personalized file system services for upper-layer application programs. Background technique [0002] At present, the global file system in the operating system can be seen by any application in the operating system. Although the chroot method can be used to limit the application program to the specified directory of the file system in the operating system, all files and subdirectories in the specified directory will affect the process. All are visible; at the same time, the application can only access the specified directory and cannot access other directories. The file system service provided in the above method is too simple, and the current operating system has not yet provided personalized file system services for upper-layer applications (processes or threads). Contents of the invention [0003] The purpose of the present invention is to provide personalized...
