In recent year’s organizations heave rising require for data imparting through oninterest access. Data handling frameworks have been proposed to associate vast scale inexactly unified information sources through a facilitating overlay, in which the intermediaries settle on steering choices to regulate customer questions to the asked for information servers. Numerous existing data handling frameworks expect that agents are trusted and accordingly just embrace server-side access control for information privacy. Notwithstanding, security of information area and informed buyer can even now be derived from metadata, (for example, inquiry and access control guidelines) traded inside the DHS, yet little consideration has been put on its assurance. In this paper, we propose a novel methodology to save protection of numerous stakeholders included in the data expediting procedure. We are among the first to formally characterize two security attacks, namely attribute-correlation attack and inference attack, and propose two countermeasure plans automaton segmentation and query segment encryption to safely impart the directing choice making obligation among a chose set of expediting servers. With extensive security investigation and trial results, we indicate that our methodology flawlessly incorporates the security requirement with question steering to give framework wide security with inconsequential overhead.
