Proofs for Integrity of Data in Cloud Storage

Abstract

data is moved to a remotely located cloud server in cloud computing. The cloud stores the data and return back to the owner whenever it is needed. But there is no guarantee that data stored in the cloud is secured and not altered by the cloud or Third Party. In order to overcome the problem of integrity of data, the user must be able to use the assist of a third party. The third party has experience in checking integrity of data, that cloud users does not have, and that is difficult for the owner to check. The data in the cloud should be correct, consistent, accessible and high quality. The aim of this research is to ensure the integrity of data and provides the proof that data is in secured manner and to provide cryptographic key to secure the data in the cloud. The proposed approach has been implemented.
