Enforcing secure and privacy in information brokering system

An Information Brokering System is one that is used for information sharing based on the client-server request. It consists of data servers and brokering components which helps client queries to locate the data servers. In traditional system, the brokers had the data confidentiality for accessing data in server side control in IBS system. At the same time the privacy is maintained in the data sharing system in data location and the data consumer queries within the IBS system. In addition with this, the end applicant will have problems such as attribute correlation and inference attacks and does not provide a system-wide coordination while information is sharing. The proposed system named Privacy Preserving Information Brokering (PPIB) using the automaton segmentation scheme and query segment encryption scheme to overcome the above discussed attacks. In this Privacy Preserving Information Brokering system the privacy and secure transmissions of data is maintained and secured trust is evaluated.
