The necessity for the information sharing increases day to day as many organizations use shared data sources to improve their data communication by improving the interoperability among them. To implement the Information sharing, there needs a Broker who act as the intermediate between the organizations and transfer data between them. This broker must be a trustable person and should not reveal the shared data to others, but it's difficult to trust a third party easily. The current system lets the Broker to make the routing decisions to direct the client query to the data servers, here the entire query content visible to the broker. To overcome the drawbacks of the current system, the proposed system explains the method to preserve privacy of multiple stakeholders involved in information brokering process. The current method becomes weaker by two attacks namely; attribute correlation attack and inference attack, which can be prevented by the proposed algorithms such as automaton segmentation and query segment encryption. By following the prescribed prevention methods the Information Brokering System (IBS) becomes more secured and privacy preserved.
