As we know that mutual data shared in distributed information sharing environment. Information brokering system (IBS) used to access information from data server. These IBS systems are on demand information access and has brokering overlay. Brokers redirects the data requester’s queries to requested data servers .In IBS systems the Brokers are not always trustable one because they may adopt access control for data confidentiality. With the purpose of providing privacy to user data and metadata we propose new system called as Privacy Preserving Information Brokering system (PPIB).PPIB is the Broker coordinator overlay network. It consists of two methods i.e. Automaton Segmentation and query segment encryption. This PPIB approach prevents two attacks as attribute correlation attack and inference attack which was present in existing IBS systems.
