| Abstract |
Publishing of data is usually only permitted when complying with a confidentiality policy. To this end, this work proposes an approach to weaken an original database instance: within a logic-oriented modeling definite knowledge is replaced by disjunctive knowledge to introduce uncertainty about confidential information. This provably disables an adversary to infer this confidential information, even if he employs his a priori knowledge and his knowledge about the protection mechanism. As evaluated based on a prototype implementation, this approach can be made highly efficient. If a heuristic – resulting only in a slight loss of availability – is employed, it can be even used in interactive scenarios.
