SAAS (Storage as a service) as one of the most important cloud computing services helps cloud users overcome the bottleneck of limited resources and expand storage without upgrading their devices. To ensure the safety and security of cloud users, data is always outsourced in encrypted format. However, encrypted data could generate a lot of storage waste in the cloud and complicate the exchange of data between authorized users. We are still facing challenges in storage and management encrypted data with deduplication. Traditional deduplication schemes always focus on particular application scenarios, where deduplication is completely controlled by data owners or servers in the cloud. They cannot flexibly satisfy the different requests from data owners based on the level of sensitivity of the data. In this paper, scheme that flexibly offers both deduplication scheme management and data security using blockchain at the same time through cloud service providers (CSPs). Author evaluate your performance with security analysis, comparison and implementation.
