The document discusses a proposed system for enhancing data storage security in cloud computing through a Third Party Auditor (TPA) that enables public auditability. It highlights the existing system's vulnerabilities and the need for independent verification of data integrity. The conclusion emphasizes the importance of a TPA in ensuring service quality and the challenge of developing verification protocols for dynamic data files.

- 3. ABSTRACT Cloud computing is a Internet based computing which enables sharing of services. Using Cloud Storage, users can remotely store their data and enjoy the on-demand high quality applications and services from a shared pool of configurable computing resources. Security in cloud is achieved by signing the data block before sending to the cloud. Moreover, users should be able to just use the cloud storage as if it is local, without worrying about the need to verify its integrity. Thus, enabling public auditability for cloud storage is of critical importance so that users can resort to a Third Party Auditor (TPA) to check the integrity of outsourced data.
- 4. Existing System In the Existing System, Cloud Computing brings new and challenging security threats towards user’s outsourced data. First of all, although the infrastructures under the cloud are much more powerful and reliable than personal computing devices, they are still facing the broad range of both internal and external threats for data integrity. Secondly, for the benefits of their own, there do exist various motivations for Cloud Service Providers to behave unfaithfully towards the cloud users regarding the status of their outsourced data.
- 5. Proposed System In the proposed system, we use the technique of providing more security by using the Third Party Auditor (TPA) . The TPA allows the user to know the information about the data stored in the cloud. When anyone tries to modify or steal the data TPA informs the user by verifying the data. The TPA doesn’t even allows the CSP to read the data of the user.

- 36. Conclusion To ensure cloud data storage security, it is critical to enable a TPA to evaluate the service quality from an objective and independent perspective. Public auditability also allows clients to delegate the integrity verification tasks to TPA while they themselves can be unreliable or not be able tocommit necessary computation resources performing continuous verifications. Another major concern is how to construct verification protocols that can accommodate dynamic data files. In this paper, we explored the problem of providing simultaneous public auditability and datadynamics for remote data integrity check in Cloud Computing
