Abstract

Inference control aims at disabling a participant to gain a piece of information to be kept confidential. Considering a provider-client architecture for information systems, we present transaction-based protocols for provider-client interactions and prove that the incorporated inference control performed by the provider is effective indeed. The interactions include the provider answering a client's query and processing update requests of two forms. Such a request is either initiated by the provider and thus possibly to be forwarded to clients in order to refresh their views, or initiated by a client according to his view and thus to be translated to the repository maintained by the provider.
