Efficient Multi-keyword Search over Encrypted Data in Untrusted Cloud Environment

In the present cloud computing paradigm, with each business moving to the cloud computing, it has become mandatory that the data be moved to the public cloud environment and managing the same without any security breach. The main problem was privacy not maintain to secure access the data in local and public cloud storage ,and another problem not securely to searching the encrypted data in biggest cloud storage .Many of the researchers to be motivated this work under the single data owner setting model and multi-owner data setting model. As more and more data are stored in the databases provided by a single cloud service provider, the data is owned by multi persons. In this approach, we have proposed a new scheme to deal with preserving the privacy in encrypted cloud data using multi-keyword searching. To enable cloud server to perform access securely to searching the data with no cognizance about the real data of both keywords and trapdoors.
