A PROPOSED APPROACH ON PRIVACY CONTINGENCY HIERARCHY MULTI-KEYWORD SEARCH IN CLOUD COMPUTING

Abstract

The cloud computing is the most awaited technology for the data owners so that they can securely outsource their data on the cloud. This allows them to retrieve the information from any part of the globe. Today’s cloud support multi owners to share their data among users securely. In our paper we have proposed a protocol called Privacy Contingency Hierarchy Multi-keyword Search (PCHMS) which is used in multi-owner cloud model. Dynamic key generation prevents the attackers from hacking the secret key
