摘要：To provide the facility of widespread collaboration, nowadays organizations are identifying the increasing sharing of information through information access based on demand. The information Brokering System (IBS) adopt a peertopeer has been proposed for information sharing from loosely associated data sources. This contains component brokers and diverse data servers, which assist the client queries to identify by the data servers.Though, lot of existing IBS accept server side deployment access control and reliable assumption on brokers, and little carefulness on privacy preserving on data and metadata stored, translating with in the IBS. In this paper we identify the privacy protection problem in information broking process. Firstly we are giving a formal representation of threat models on mainly focus on two attacks inference attack and attribute correlation attack. After that we are proposing a broker coordinator overlay as well as 2 types of schemes, query segment encryption scheme and automaton segmentation system, those are used to share securely query routing information from set of broker services. With brief analysis on confidentiality, endtoend performance and scalability, we represent that our proposed system combine query routing and security enforcement while providing systemwide privacy with reasonable above your head.
