An effective storage management in a twin cloud architecture using an authorized deduplication technique

Abstract

Data deduplication is the technique of reduction in the data which keeps only one physical copy and generates pointers to that copy for referencing other redundant data. To secure the confidentiality of private data throughout deduplication, the convergent cryptography technique is used to encode the information before uploading it onto the general public cloud. In our paper, we've got an inclination to present the deduplication-aware resemblance detection and elimination (DARE) scheme that supports authorization in twin cloud surroundings. This scheme uses a duplicate-adjacency info for likeness detection wherever we've got to consider any 2 information blocks to be similar provided that their respective adjacent information blocks are duplicate. Our proposed system achieves deduplication on encrypted data with minimum overhead and also enhances the security by providing authorization in hybrid cloud environment.
