摘要：A hybrid cloud is a combination of public and private clouds together and a technology that enables data and application portability. Proposed system aiming to solving the problem of deduplication efficiently with differential privileges in cloud co mputing. A hybrid cloud architecture consisting of a public cloud and a private cloud and the data owners only use their data storage by utilizing public cloud while the data operation like storing and retrieving is managed in private cloud. To make data management accessible in cloud computing, d eduplication has been a well technique recently is use. Deduplication reduces your band width requirements, speeds up the data transfers, and it keeps your cloud storage needs to a minimum. Proposed system present so me new deduplication constructions which supports authorized duplicate check in hybrid cloud architecture. To maintain the confidentiality of data the convergent encryption technique has been used to encrypt the data before outsourcing. Authorized deduplication system support differential authorization duplicate check. As a proof of concept, a prototype is implemented in authorized duplicate check scheme and performs test bed experiments using prototype, authorized duplicate check scheme obtains minimal overhead co mpared to normal operations.
