Cloud computing is an alternative to traditional information technology due to its services. In this paper, a new theory has been introduced three way integrity algorithm. Here the authors are checking the accuracy of Cloud Service Provider (CSP) and Third Party Auditor (TPA). It gives an efficient data integrity mechanism between the client and the cloud by using RSA with digital signature on the message digest instead of on the whole data to make computations faster. Their public auditing system can be constructed from the above auditing scheme in two phases, setup and audit phase.
