Conventionally, in this type of usage rights management system, it has not been possible to set usage rights for each user for each record that constitutes a file.

That is, in the conventional usage rights management system, a user who has usage rights to a file exercises usage rights over all records of that file.

[Problem to be solved by the invention]

In the conventional usage rights management method described above, a user who has usage rights for a file can exercise usage rights over all records of that file. It is not possible to allow each user to refer to only some records (each user can not only access records related to him or herself in the file, but also records related to other users). ), the disadvantage is that file security is incomplete.

In view of the above-mentioned points, an object of the present invention is to limit the records that each user can access with respect to a file that is open to many users, and to enable file security protection on a record-by-record basis. The objective is to provide a usage rights management method.

The apparatus includes record unit usage right updating means, record unit usage right deletion means, and record unit usage right reference means.

[Effect]

In the usage rights management method of the present invention, a record-based usage rights control file holds usage rights for each user on a record basis,
The record unit usage right registration means registers the record unit usage right in the record unit usage right control file,
The record unit usage right update means updates the record unit usage right for the record unit usage rights control file,
The record unit usage right deletion means deletes the record unit usage right for the record unit usage rights control file,
The record-based usage right reference means refers to the record-based usage rights in the record-based usage rights control file;
The record-based usage right control means controls the record-based usage rights registration means, the record-based usage rights update means, the record-based usage rights deletion means, and the record-based usage rights reference means.

〔Example〕

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

FIG. 1 is a block diagram showing the configuration of an embodiment of the usage rights management method of the present invention.
A record unit usage right control file 1, a record unit usage right control means 2, a record unit usage right registration means 3,
It is configured to include a record unit usage right updating means 4, a record unit usage right deletion means 5, and a record unit usage right reference means 6.

Figure 2 shows the format of the record-based usage right control file 1 (
2 is a diagram illustrating the format of records constituting the record-based usage right control file 1. FIG. The record-based usage rights control file 1 includes a field for storing user names, a field for storing file names, a field for storing record numbers, and usage rights for each record (existing in the file specified by the file name). usage rights of a user identified by user name for a record identified by record number)
(In this way, the record-based usage rights control file 1 holds usage rights for each user on a record-by-record basis.)

Next, the operation of the usage rights management system of this embodiment configured as described above will be explained.

When record-based usage rights are registered for records in a certain file (a file open to many users), the following processing is performed.

The record unit usage right control means 2 outputs the record unit usage right registration information 201 having the user name, file name, and record number related to the usage right of the record unit to be registered, and the usage right of the record unit to be registered.

The record unit usage right registration means 3 inputs the record unit usage right registration information 201 and records the user name, file name, record number, and record unit usage right to be registered in the record unit usage right registration information 201. Add (register) the record that has the record to the record-based usage right control file l.

When the usage rights of a record in a certain file (a file open to many users) are updated on a record-by-record basis, the following processing is performed.

The record unit usage right control means 2 includes the user name, file name, and record number related to the record unit usage right to be updated, the record unit usage right before the update, and the record flower that has the record unit usage right after the update. The location usage update information 202 is output.

The record unit usage right update means 4 inputs the record unit usage right update information 202 and updates the record unit usage right according to the user name, file name, record number, and record unit usage right in the record unit usage right update information 202. A record in the record unit usage right control file 1 is identified, and the value of the field that stores the record unit usage right in the specified record is updated to the record unit usage right update information 202.
Update the usage rights value for each record after the update.

When the right to use a record in a record in a certain file (a file open to many users) is deleted, the following process is performed.

The record unit usage right control means 2 outputs the record unit usage right deletion information 203 that includes the user name, file name, and record number related to the usage right of the record unit to be deleted, and the usage method of the record unit to be deleted.

The record unit usage right deletion means 5 inputs the record unit usage right deletion information 203 and uses the user name, file name, record number, and usage of the record to be deleted in the record unit usage right deletion information 203. A record in the record unit usage right control file 1 is specified, and the specified record is deleted.

When reference is made to usage rights in record units for records in a certain file (a file open to many users), the following processing is performed.

The record-based usage right control means 2 outputs the user name, file name, and record number related to the referenced record-based usage right, as well as record-based usage rights reference information 204 that includes the referenced record-based usage right.

The record unit usage right reference means 6 inputs the record unit usage right reference information 204, and identifies the user name, file name, and record unit that has the record unit usage right to be referenced in the record unit usage right reference information f1204. Records in the usage right control file 1 are searched, and the value of the field that stores the record number in the searched record is output to the record unit usage right control means 2 as the record unit usage right reference result information 601 (the record unit usage The right reference result information 601 is obtained by the record unit usage right control means 2.
provided to users, etc.).

〔Effect of the invention〕

As explained above, the present invention includes a record unit usage right control file, a record unit usage right registration means, a record unit usage right updating means, a record unit usage right deletion means, a record unit usage right reference means, and a record unit usage right control means. By creating a file and managing file usage rights on a record-by-record basis, it is possible to limit the records that each user can access for files that are open to many users, and to protect the confidentiality of files on a record-by-record basis. It has the effect of making it possible.
