SECURE DEDUP WITH ENCRYPTED DATA

Cloud computing is one of the way of service provision over the internet today. Cloud computing is the developing a next level from the last decades. One of the drawbacks, cloud storage is a privacy security at the CSP. So, the chunks users stored by the encrypted data for the purpose of security. Cloud storage vendors which allow to decreases chunked data and more efficient storage saver. One of the best techniques is deduplication, duplicate data is stored only once .In this paper, propose a checksum algorithm for distributing objects to agents, in a way that improves our chances of identifying a leaker. We evaluate its performance based on effective and efficient storage level. Its support data access control and revocation at the same time
