摘要：Cloud-based outsourced storage relieves the client's load for storage management and preservation by providing an equivalently scalable, low-cost, location-independent platform. Clients no longer have physical control of data indicates that they are facing a potentially frightening risk for missing or corrupted data. To keep away from the security risks, audit services are significant to make sure that the integrity and availability of outsourced data. Provable data possession (PDP), which is a cryptographic technique for verifying the integrity of data without retrieving it at an un trusted server, can be used to recognize audit services. In this we introduced the construction of an well-organized audit service for data integrity in clouds. Profiting from the typical interactive verification system, we projected an interactive audit procedure to implement the audit service based on a third party auditor. In this audit examination, the third party auditor can concern a periodic authentication to check the change of outsourced data by providing an optimized to-do list. To understand the audit model, we only need to preserve the security of the third party auditor and organize an insubstantial daemon to execute the verification protocol. We present an capable method for selecting an optimal parameter value to minimize computational expenditure of cloud audit services. Our results demonstrate the effectiveness of our approach.
