An increasing need has been raise now a days for information sharing on demand of access. To the requested data servers, the brokers make routing decisions to direct client queries, to connect large scale loosely information brokering systems have been proposed federated data sources via a brokering overlay. Brokers are trusted in many existing IBSs, only adopt server side access control for data confidentiality. From metadata exchanged within the IBSs, privacy of data location and data

To preserve privacy of multiple stakeholders involved, in the information brokering process in this paper, we propose a novel approach. A selected set of brokering servers, to securely share the routing decision making responsibility, the paper propose two counter measure schemes automaton segmentation and query segment encryption, we are among the first to formally define two privacy attacks namely attribute correlation attack and inference attack. With comprehensive security analysis and experimental results, to provide system wide security with insignificant overhead, we show that our approach seamlessly integrates security enforcement with query routing.
