Public auditing for cloud storage is of critical importance as the users relies on semi-trusted cloud storage service for data sharing which does not guarantee/assure the integrity of the data being stored. With public auditing of clouds, users resort to a third party auditor (TPA) who verify and assure the internal consistency/lack of corruption of their data in cloud storage services. Despite the good work previously done by researchers in auditing while preserving privacy, still available mechanisms do not efficiently conceal users? privacy from TPA during sharing of data and yet supporting data and group dynamics. In this paper, we propose privacy preserving auditing scheme that exploits the ring signature to calculate verifications needed to audit data integrity. In this proposed approach, the identities of the user are kept private from public verifier and dynamic groups are supported ?that is a new user can be added into the group and an existing group member can be revoked during data sharing.
