Third Party Auditing (TPA) for Data Storage and Maintaining Integrity of Data in Cloud

Cloud storage enables users to remotely store their data. Many users place their data in the cloud and so data integrity is very important issue in cloud storage. After moving the data to the cloud, owner hopes that their data and applications are in secured manner. But that hope may fail sometimes that is the owner’s data may be altered or deleted. Numerous present remote integrity inspection methods can only serve for static collection data and not to the audit service as the data in the cloud can be dynamically updated. Thus, an efficient and secure dynamic auditing protocol is desired to convince data owners that the data are correctly stored in the cloud. Thus, design an auditing framework for cloud storage systems can be built and put forwards an efficient and privacy-preserving auditing protocol. Then, here extend auditing protocol to support the data dynamic operations, which is efficient and provably secure. Again, further extending to provide the data integrity to the data present in cloud by using algorithms. Again to preserve integrity of file stored in cloud and provide better privacy for user slicing technique is added.
