Deduplication is the method of eliminating replicas of data. This paper is widely used in cloud computing to reduce storage space and bandwidth. Even though data deduplication brings a lot of benefits, it does not provide any security measures for user's sensitive data. To protect these sensitive data from insiders and outsiders attacks, a hybrid cloud approach is used. Convergent encryption technique has been proposed to protect the confidentiality of sensitive data while supporting deduplication, which encrypt the data before outsourcing. The unauthorized access will be prevented by proof of ownership protocol.
