Privacy Preserving Auditing For Cloud Storage

Cloud storage provides users to easily store their data and enjoy the good quality of cloud applications which is need not install in any local hardware and software system. such a service is also gives users control of their outsourced data, which also provides control to the security problems regarding the correctness of the data storage in the cloud. The main goal of cloud computing the data protection, secure and the process data stored under the property of users. As the data which is stored at the remote server how the cloud users will get the confirmation about data which are stored. Thats why cloud storage should have some technique and mechanism which will specify correctness of data storage and integrity of data stored on cloud. For that users can resort to a third-party auditor (TPA) which is to check the integrity of outsourced data, TPA should be able to efficiently audit the data storage on cloud. To introduce an effective and secure TPA, the auditing process should bring in no new vulnerabilities toward user data privacy, and no online additional burden to user. In this paper, we propose system for a cloud storage which is the secure and supporting privacy-preserving public auditing. The proposed system perform for multiple users auditing process simultaneously and efficiently.
