Controlled Interaction Execution is a specific concept of inference control for logic-oriented information systems. Interactions include query answering, update processing and data publishing, and operational control is based on declarative policies. Complementing a previous survey on this concept, in this work we treat various forms of confidentiality policies regarding their syntax, semantics, algorithms and pragmatics.In each case, we consider an information provider’s interest in confidentiality as an exception from his general willingness and agreement to share information with a client.
