Abstract

We survey the motivation, the main insight and the perspective of our approach to policy-driven inference control of server-client interactions for a logic-oriented information system. Basically, our approach aims to confine the usability of the data transmitted by the server to a client. The confinement is achieved by enforcing an invariant that, at any point in time, a client’s view on the actual information system is kept inference-proof: the information content of the data available to the client does not violate any protection requirement expressed by a declarative confidentiality policy. In this context, the information content of data and, accordingly, the inference-proofness of such data crucially depend on the client’s a priori knowledge, general reasoning capabilities and awareness of the control mechanism. We identify various parameters of the approach, outline control mechanisms to enforce the goals, and sketch the methods employed for a formal verification.
