Multilevel Cryptosystem for Authorized Deduplication in Hybrid Cloud

P. Narasimhulu | Jayavarthini.C

Abstract: Data deduplication is the one of necessary data compression technique, for eliminating redundant copies of data in the cloud. It has been widely used in cloud storage, eliminating redundant data can significantly shrink storage requirements and improve bandwidth efficiency. To support data confidentiality for the sensitive data. Attribute based encryption has been implemented along with multilevel crypto system, encrypt the data before outsourcing and protect better security for the data in the cloud, In this paper makes the first attempt to formally addressing the problem of authorization of data deduplication. Different users consider duplicate check in the data itself. We also implement several new duplications systems supporting authorized duplicate check in hybrid cloud architecture. Security analysis explains about the secured terms in the proposed security model. We show that our proposed duplicate check scheme incurs minimum overhead compare to normal operations
