Abstract-Cloud storage as one of the most important services of cloud computing helps cloud users break the bottleneck of restricted resources and expand their storage without upgrading their devices. In order to guarantee the security and privacy of cloud users, data are always outsourced in an encrypted form. However, encrypted data could incur much waste of cloud storage and complicate data sharing among authorized users. We are still facing challenges on encrypted data storage and management with deduplication. Traditional deduplication schemes always focus on specific application scenarios, in which the deduplication is completely controlled by either data owners or cloud servers. They cannot flexibly satisfy various demands of data owners according to the level of data sensitivity. In this paper, we propose a heterogeneous data storage management scheme, which flexibly offers both deduplication management and access control at the same time across multiple Cloud Service Providers (CSPs). We evaluate its performance with security analysis, comparison and implementation. The results show its security, effectiveness and efficiency towards potential practical usage.

Data De-duplication is one of the effective ways now a days employed in the cloud computing. Energy consumption ratio of IT companies is increasing day by day and reason for it is storing redundant copy of data. Data De-duplication is a cutting edge technology that is used to remove redundant copies of data and store only unique copy of data. It reduces network bandwidth and storage space as well. There are many Data De-duplication methods used however in proposed work main focus is on block level Data De-duplication along with security. In Block level Data De-duplication redundancy would be checked based on blocks of data.

“…Because it is possible that same plaintexts may lead to different ciphertexts. If one can realize data deduplication on ciphertexts, the cloud server must be able to identify all of the ciphertexts of the same plaintext [3] . One more thing needs to be there in data deduplication is authorized deduplication in which users would have set of privileges because in many of applications differential authorized duplication is needed.…”

Now days due to advancement of storage technology and computer technology, larger fraction of data is being maintained in digitized form. The same data is stored over and over again, consuming unnecessary storage space on the disc. Deduplication is ideal for highly redundant operations like backup, which requires repeatedly coping and storing the same data. Data deduplication is one of the most alive topics in storage because it enables companies to save a lot of money on storage costs. For cloud provider it is very helpful because you can deduplicate what you store. Due to reduction in cost it is being more popular. This paper will briefly describe Data Deduplication and give a comprehensive survey.
