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. <P>COPYRIGHT: (C)2007,JPO&INPIT |
