摘要：In cloud computing paradigm it is not only used to store the user’s data and also allows the users toshare the data among them. Sometimes the integrity of cloud data is loss due to the existence of hardware/softwarefailures and human errors. To prevent this problem several mechanisms have been designed to allow both data ownersand public verifiers to efficiently audit cloud data integrity without retrieving the entire data from the cloud server.However, public auditing on the integrity of shared data with these existing mechanisms will inevitably revealconfidential information identity privacy to public verifiers. In this paper, we undergo a survey on various privacypreservingmechanism that supports public auditing on shared data stored in the cloud. In particular, we exploit ringsignatures to compute verification metadata needed to audit the correctness of shared data.
