Abstract

PURPOSE:To prevent a lack of resources by providing a file management file for management of generators, use rights, deletion terms, etc., of files and permitting the access by the right set to a file and setting the deletion term to automatically delete the file. CONSTITUTION:File names, generator names, deletion terms, and user rights are registered, updated, and deleted in the file management file by the right operation. The input right, the reference right, the deletion right, and the update right of data are prepared as use rights, and all these rights are given to the generator of the file, and only this generator can give these rights to the others. Only the person whom use rights are given is permitted to perform the data operation and inputs, refers to, deletes, and updates actual data. The deletion term preliminarily registered by the generator is referred at each time of the change of the date of computer use to automatically delete files whose terms expire. Thus, resources are effectively used.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a management system using file data security protection.

[Conventional technology]

Conventionally, system users have been able to freely create, delete, and refer to files.

[Problem to be solved by the invention]

In the conventional system described above, since system users can freely create files, there are many cases where files cannot be deleted even though they are not being used because the creator and purpose are unknown, resulting in resource shortages. It may happen.

Furthermore, since any file can be accessed, data confidentiality has been viewed as a problem.

[Means to solve the problem]

The configuration of the file management system of the present invention includes a file management file for managing file creators, usage rights, deletion deadlines, etc., sets rights to the files, and enables access to the files based on the rights. , the file can be automatically deleted by setting a deletion deadline for the file.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIGS. 1(a) to 1(C) are flowcharts showing the method of one embodiment of the present invention, which consists of three components: (a) rights manipulation, (b) data manipulation, and (C) automatic deletion.

The rights operation shown in Figure 1 (a) does not involve manipulating the actual data, but rather registering, updating, and deleting the file name, compiler name, deletion date, and usage rights in the file management file. .

Usage rights include input rights that allow data to be entered, reference rights that allow data to be referenced, deletion rights that allow data deletion, and update rights that allow data to be updated. Only the creator can give this right to others.

The data operations shown in FIG. 1(b) are permitted only to those who have been granted usage rights, and are for inputting, referencing, deleting, and updating actual data.

In the automatic deletion shown in FIG. 1(C), the deletion date registered in advance by the creator is referred to each time the date of computer use changes, and files whose expiration date is deleted are deleted.

〔Effect of the invention〕

By implementing this method, data can be protected confidentially, and resources can be effectively utilized by deleting expired files.

FIGS. 1(a) to 1(C) are flowcharts showing the method of one embodiment of the present invention.

Claims (1)

[Claims] Provide a file management file for managing file creators, usage rights, deletion deadlines, etc., set rights to the files, enable access to the files with those rights, and set deletion deadlines for the files.
