Summary:PROBLEM TO BE SOLVED: To calculate a similarity of policies or policy groups which reflects the properties of the policies or policy groups. SOLUTION: A similarity calculation part 12 counts, for example, the number of different points in subject name between two rules, and calculates and adds the product of the number with a set value to the similarity between policies, performs the same operation for object name and for access method name. When coincident points are present between the two rules for subject name, object name and access method name, and permission set values of the two rules are not coincident, the calculation part calculates the product of the respective numbers of coincident points, calculates and adds the product of it with a set value to the similarity between policies, and sets the minus sign.
