<p>A priority restriction resolution means generates in a temporary storage means a set of rights permissions without priority restriction from a set of rights permissions with priority restrictions extracted relating to a role. At that point, the priority restriction resolution means reads out rights permissions from the set of rights permissions with priority restrictions in accordance with the priority satisfying the priority restriction. When an object of the read-out rights permission includes an object of the rights permission having the same action, which has already been generated in the temporary storage means and both permission identifiers are different from each other, the priority restriction resolution means divides the rights permission read out this time into a plurality of rights permissions having an object with the same granularity as the included object, thereby storing in the temporary storage means only the rights permission having objects which are different from the included object.</p> |
