ABSTRACT
Cloud computing offers a quality atmosphere for emergent quantity of information and practices that effort on a choice of requests and services by means of on-demand Self-services. The cloud storage service would carry irrevocable fatalities to users in view of the fact that their data are stored into an uncertain storage pool outside the enterprises as important services are vulnerable to attacks. To present a well-organized audit service to make sure the truthfulness and accessibility of the stored data is essential for cloud service providers. To decrease the audit costs per verification and implement abnormal detection timely, an efficient mechanism with respect to probabilistic queries and periodic verification is proposed in this paper. In addition, to minimize computational overheads of cloud audit services we present an efficient method for selecting an optimal parameter value. For authenticating the integrity of data without retrieving it at an un-trusted server a Provable data possession which is a cryptographic technique is used, and can be used to realize audit services. To put off the fraud of prover we deal with the building of an interactive Provable data possession protocol and the escape of verified data profiting from the interactive zero-knowledge proof system.
