Access Control Mechanism for Authorized Query Predicates on Sensitive data

Abstract

The aim of this paper is to provide better security and minimum level of precision to the obtained data, for that in this paper an accuracy constrained privacy preserving access control mechanism is implemented with additional constraint on each selection predicate called imprecision bounds. The accuracy constraints are satisfied for multiple roles. We propose heuristics for anonymization algorithms to show empirically that the proposed approach satisfies imprecision bounds for more permissions and has lower total imprecision than the current state of the art.
