―Data Integrity Proof in Cloud Storage‖

Abstract — Cloud computing is an important application for storage of data in the cloud. Cloud computing platform avoid the Burdon of local data storage and also reduce maintaince cost. In cloud storage data is move to a remotely located cloud server on which user does not have any control. Cloud faithfully stores the data and return back to the owner whenever is needed, but there is no guarantee that the data store in the cloud is secure or not modify by cloud. In this paper we provide a scheme which gives an assurance of data integrity in the cloud storage in which the owner of the data can check the correctness of his data in the cloud. This proof can be agreeing upon by both cloud and the client and can be incorporated in the service level agreement. This scheme ensures that the storage at the client side is minimal which will be useful for the thin client and small scale company
