In this paper, a new scheme has been introduced, \"Two way integrity algorithm\". The paper presents a way to implement Third Party Auditor (TPA) which not only checks the reliability of Cloud Service Provider (CSP) but also checks the consistency and accountability of data. This paper addresses this challenging open issue of integrity, confidentiality and authentication of data. It provides an efficient data integrity mechanism between the client and the cloud service provider by applying RSA with digital signature on the message digest instead of on the whole data to make the computations faster.
