Cloud storage provides users to easily store their data and enjoy the good quality cloud applications need not install in local hardware and software system. So benefits are clear, such a service is also gives users’ physical control of their outsourced data, which provides control over security problems towards the correctness of the storage data in the cloud. The main goal of cloud computing concept is to secure, the data protection and the process which come under the property of users. As the data is stored at the remote place how users will get the confirmation about data which are stored. That is why cloud storage should have some technique which will specify storage correctness and integrity of data stored on cloud. Users can resort to a third-party auditor (TPA) to check the integrity of outsourced data and be worry free. TPA should be able to efficiently audit the cloud data storage without demanding the local copy of data. 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 a cloud storage system which is secure and supporting privacy-preserving public auditing. The proposed system perform audits for multiple users simultaneously and efficiently.

Keywords:. Data storage, privacy preserving, public audit ability, cloud computing, delegation, batch verification, zero knowledge.
