ABSTRACT:
When determining whether or not access by a user should be permitted by using policies, an access control determination device of the present invention expresses the access by the user to the data source with a predetermined path, retrieves an appropriate policy out of stored policies on the basis of the predetermined path, calculates an access permission value on the basis of the predetermined path, calculates an access effect value on the basis of the predetermined path and the policy which the policy retrieving unit has retrieved, and determines whether or not the access by the user to the data source should be permitted on the basis of the access permission value and the access effect value.
