Abstract— The basic notion of deduplication is storage of duplicate data only for a single time. Thus, a user willing to upload a stored file will have to be first added by the cloud provider in the owner list for that particular file. This is the reason why deduplication has been rapidly adopted by various providers of cloud storage. Today, it has become a popular approach for minimizing storage space and for uploading bandwidth and assists largely in increasing the scalability of data. Deduplication also eliminates the fear of surplus data by maintaining a single physical copy and refers any surplus data to this copy and is the best alternative of multiple data copies having the same data.

Keywords— Encryption, De-Duplication, Convergent Encryption.
