Nowadays it is becoming common for enterprises to cooperate in certain areas and compete. To facilitate this requirement enterprise information systems are designed as distributed network systems, where existing information systems and new components are connected together via a middleware. One such widely accepted and commonly used system is Distributed information brokering System (DIBS) which is a peer-to-peer overlay network that comprises diverse data servers and brokering components helping client queries locate the data. Literature on information integration across such systems tacitly assumes that the data can be revealed to the others. However, there is an increasing need for sharing information across autonomous entities in such a way that no information apart from the answer to the query is revealed. We formalize the notion of minimal information sharing across such databases, and develop protocol such that no single entity possess the complete data that can be misused unless it is passed on to the requested entity securely.
