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.

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.

 

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.

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
