Without appropriate security and privacy solutions designed for clouds this computing paradigm could become a huge failure. There is a lot of research being made to spot out the issues with these cloud service providers and cloud security in general. This paper is on regard of one of the key issue-privacy that occur in the context of cloud computing and analyze the various works being done to solve the issues in privacy and thus to ensure privacy to outsourced data on cloud storage
