A Review on Privacy-Conserving Public Auditing for Shared Data in Cloud Computing, with a Focus on User Revocation

The term cloud computing has been emerged as a computing network over the Internet. Cloud data indulge storing of the data in the cloud as well as has sharing capability among multiple users. Due to failures of human or hardware and even Software errors cloud data is associated with data integrity. Several mechanisms have been proposed in order to allow both the data owners as well as the public auditors to audit cloud data integrity efficiently without retrieving the entire data from the cloud servers. A Third Party Auditor (TPA) will perform integrity checking and the identity of the signer on each block in shared data is kept private from them. In this paper, we only survey for auditing the integrity of shared data in the cloud with efficient user revocation while still conserving identity privacy.
