Cloud Computing is a collection of servers hosted on the internet. User can request the cloud provider to get the services. One of the advantage of cloud storage is that the originality(integrity) of the data is maintained in the cloud. It can be achieved by various cryptographic techniques. This new data storage paradigm introduces some security challenges, which requires an auditing service to check the integrity of the data. In this paper, a various integrity checking schemes namely Provable Data Possession(PDP), Compact Proofs of Retrievability(CPOR), Dynamic Provable Data Possession(DPDP), Auditing and CPDP are analyzed and also conclude the best strategy to store the data.
