At present, common multi-user operating systems include a Windows operating system and a Linux operating system, which are basically similar to a single-user operating system in use, wherein in a Windows series operating system, when multiple users operate, data (including a C disk, a D disk, an E disk, an F disk, and the like) on a hard disk can be accessed and shared by different users in most cases except for a part of specially-designed directories, and thus resource files on the hard disk can not be completely distinguished to belong to a certain user, or private file resources of a certain user (only the resource files on the C disk are distinguished under the user directory, but the resource files on the D disk, the E disk and the F disk are not too many distinguished, and all users can be basically shared); in the Linux operating system, the authority of each user is different, most directories and files on the hard disk have different user authorities, but under the condition of large data, all the users can read (cannot write, cannot execute and the like), and then when different users log in the Linux system, the directory structures and file lists of other users and the file contents (cannot be rewritten and can be rewritten if the users have writable authority) can still be seen.
In summary, in the existing multi-user operating system, no matter the Windows operating system or the Linux operating system, for the reading aspect, all file resources of different users do not have a strict permission difference except for the system disk, and are independent of the user. For example, it is currently not well implemented: the user a cannot view all file resources of the user B (unless the user B stores the file resources in the shared common directory), that is, all file resources of the user a can only be seen by the user a, and only the user a can perform operations such as modification and deletion, the user B cannot view any file resource of the user a (unless the user a puts the file resources in the shared common directory), and the user B cannot perform operations such as modification and deletion.
