Distributed information systems emerged as solution for the needs of enterprises that share information via on-demand access. Information Brokering Systems (IBSs) came into existence to leverage usefulness of sharing information among organizations. The IBS is responsible to integrate loosely coupled systems forming a brokering overlay. The existing IBSs believe that the brokers are trusted and data can be shared through them confidently. However, adversaries can infer information from the metadata available. This is the problem to be addressed. Recently, the researcher proposed an approach for privacy preserving information brokering.
