Cloud computing is an internet based computing which enables obtaining resources (hardware, software, platform and services) from the internet on a scalable basis. Many users place their data in the cloud, so correctness of data integrity and security are prime concerns. This paper studies the problem of ensuring the integrity and security of data storage in cloud computing. To ensure the correctness of data, the authors consider the task of allowing a Third Party Auditor (TPA), on behalf of the cloud client to verify the integrity of the data stored in the cloud.
