Data reduction has become increasingly important in storage systems due to the explosive growth of digital data in the world that has ushered in the decentralized storage approach. One of the main challenges facing large-scale data reduction is how to maximally detect and eliminate redundancy at very low overheads. To guarantee the security of cloud users, data is always outsourced in encrypted format. In this paper, a deduplication resemblance detection and elimination scheme that effectively exploits existing duplicate information for highly efficient resemblance detection in data deduplication based storage systems. Conventional deduplication conspires always focus on specific application situations, where deduplication is handled by data owners or servers in the cloud. They can not adaptably fulfill demands that are unique from data owners based on the level of data sensitivity. In this paper, the plan all the while gives the executives of the deduplication plan and access control over cloud service providers (CSPs).
