Computer readable medium for access right management, access right management apparatus and data processing system

An access right management apparatus including:

• a correspondence read unit that reads correspondence information from a storage unit for storing correspondence information indicating the correspondence between a unique access right of an access right in a data management unit and a common access right of an access right in an interface providing unit as for the data management unit for managing electronic data and the access right to the electronic data and the interface providing unit intervening between an operation main body for giving an operation command to the electronic data and the data management unit for providing an operation interface made common about different types of the data management unit for the operation main body;
• a request acceptance unit that accepts a setting request for requesting setting of the common access right;
• and
• a determination unit that determines whether or not the setting request of the common access right accepted by the request acceptance unit is a non-match request wherein correspondence with a different common access right exists for the unique access right corresponding to that the common access right based on the correspondence information read by the correspondence read unit,
• wherein in correspondence between one unique access right and a plurality of common access rights, the common access rights are ranked, and
• wherein when correspondence with a higher-order different common access right than a common access right requested for setting exists for the unique access right corresponding to the common access right, the determination unit determines that the request for the setting is a non-match request.

Data processing system comprising:

• a data management unit that manages electronic data and the access right to the electronic data;
• an interface providing unit that intervenes between an operation main body for giving an operation command to the electronic data and the data management unit for providing an operation interface made common about different types of the data management unit for the operation main body;
• a storage unit that stores correspondence information indicating the correspondence between a unique access right of an access right in the data management unit and a common access right of an access right in the interface providing unit;
• a request acceptance unit that accepting a setting request for requesting setting of the common access right;
• and
• a determination unit that determines whether or not the setting request of the common access right accepted by the request acceptance unit is a non-match request wherein correspondence with a different common access right exists for the unique access right corresponding to that the common access right based on the correspondence information stored in the storage unit,
• wherein in correspondence between one unique access right and a plurality of common access rights, the common access rights are ranked, and
• wherein when correspondence with a higher-order different common access right than a common access right requested for setting exists for the unique access right corresponding to the common access right, the determination unit determines that the request for the setting is a non-match request.
