To reduce the amount of storage space and save bandwidth in cloud storage various data compression techniques are used, data deduplication is one of the important data compression technique. Data deduplication removes the duplicate copies of repeating data. To encrypt the sensitive data, the convergent encryption technique has been proposed. It is first formal attempt to address the problem of secure authorized data deduplication. Data and the differential privileges of users are considered while duplicate check, thus differing from traditional deduplication systems.
