Secure Information Brokering in Distributed Information Sharing

Priyanka M. Jamunkar, Prof. G. M. Bhandari

Abstract: Information Brokering System (IBS) on a peer-to-peer overlay has been proposed to support information sharing among loosely federated data sources. Todays organizations raise increasing needs for information sharing through on demand information access. To aid requirement of organization information systems are designed as distributed network systems, where existing information systems and new components are connected together using a middleware. Many existing IBSs assume that brokers are trusted and only adopt server-side access control for data condentiality. One commonly accepted and used system is Distributed Information Brokering System, which is a peer-to-peer network that comprises different data servers, and brokering components helping client queries locate the data. Preserve privacy of multiple stakeholders involved in the information brokering process and dene two privacy attacks, attribute-correlation attack and inference attack, and propose two countermeasure schemes automaton segmentation and query segment encryption to securely share the routing decision. The idea of information sharing across such databases, and increase protocol that no single entity hold the complete data that can be misused but it is passed on to the requested entity securely.
