Information Brokering Systems are attracting and increasing attention as an efficient means of sharing data among large, diverse and dynamic sets of user. The peer from logical over lay network by establishing links to some other peers they know are discover. A user in a peer-to-peer system in issues quires the describe data of interest the quires are propagated throw the overlay network to locate peer that provide data relevant to the query and only matching results are returned to the user. Information Brokering System (IBS) atop a peer-to-peer overlay has been proposed to support information sharing among loosely federated data sources. In existing IBSs adopt server side access control deployment and honest assumptions on brokers, and shack little observation on privacy of data and metadata stored and exchanged within the IBS. This paper studies the problem of privacy protection in information brokering process (PPIB). Then, this paper propose a broker-coordinator face, as well as two schemes, automaton segmentation scheme and query segment encryption scheme, to share the secure query routing use among a set of brokering servers. With comprehensive survey on privacy, end-to-end performance, and scalability, we show that the proposed system can combine security enforcement and query routing while preserving system-wide privacy with reasonable overhead. Further enhanced by Information Brokering System using Data Encryption Standard (DES), Digital Signature and XOR swap algorithm.
