A New Hybrid Cloud Approach for Secure Authorized Deduplication

S. Archana, Jyoti Gaikwad


Data deduplication is one of predominant data compression methods for getting rid of reproduction copies of repeating data and has been broadly used in cloud storage to control the quantity of storage space and save bandwidth. To safeguard the confidentiality of sensitive data even as supporting deduplication the convergent encryption process has been proposed to encrypt the data earlier than outsourcing. To better preserve information protection, this work makes the primary attempt to formally handle the difficulty of licensed data deduplication. As compared to ordinary deduplication techniques, the differential privileges of users are additional regarded in reproduction examine apart from the data itself. The work also grants a number of new deduplication constructions aiding approved reproduction assess in hybrid cloud structure. Security analysis demonstrates that our scheme is relaxed in phrases of the definitions particular in the proposed security mannequin. As a proof of proposal, the work put in force a prototype of proposed approved duplicate examine scheme and conduct confirmed experiments utilising the prototype.  

Key Words: Data deduplication; Convergent encryption; Confidentiality;  Hybrid cloud; Authorized Duplicate check.
