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
