%X A problem of private privileges that child role couldn't obtain because of inherited relation in the RBAC model of information grid was researched,two present resolvations that used private roles and deepness fist notes were analyzed,from which they could result in role inflate and compages explosion.Then a new resolvation with privilege transmit deepness was presented,that was,every privilege of the role could get public attributions,private attributions and a privilege transmit deepness.Meanwhile an algorithm to obtain privilege sets of each role was given.
