The problem in cloud computing is that they are facing a potentially formidable risk for missing or corrupted data. To avoid the security risks, audit services are critical to ensure the integrity and availability of outsourced data. In this paper, the authors propose a audit system architecture that provide a proof of data integrity is given by PDP (Provable Data Possession) or POR (Proof Of Retrievability) to verify the integrity of data without retrieving it at untrusted server can be used to realize audit service (i.e. to check the data has been illegally modified or deleted) via Service Level Agreement (SLA).
