<P>PROBLEM TO BE SOLVED: To detect/extract contradiction about such complicate relations as SoD constraint based on relations between a plurality of subjects or objects. <P>SOLUTION: This access right management system for verifying the contradiction of access rights is provided with a rule comparing means which generates a rule with constraint by applying attributes specifying constraint to an access right to be derived from a policy including access right definitions to make a rule storage means store it, and which compares position relations on a coordinate space of points using a value configuring access right by using the access rights included in the rule with constraint stored in the rule storage means as objects to verify the contradiction of the access rights. <P>COPYRIGHT: (C)2009,JPO&INPIT |
