ABSTRACT Enjoy the cloud applications without the burden of local
hardware and software management. Possess many security risks towards the correctness and
dependability of data in cloud. We propose in this paper a flexible distributed storage with very
lightweight communication and computation cost. It not only ensures strong cloud storage, but also achieves fast
data error localization. The proposed design further supports secure and efficient
dynamic operations on outsourced data. Analysis shows the proposed scheme is highly efficient and
resilient against Byzantine failure, malicious data modification attack, and even server colluding attacks.

1Existing System and Limitations
Byzantine Error Occurrence.
Allocating a Third-party for Supervision.
No Integration of Database in Servers.
Pre-Requisition for Client manipulation

2Proposed System
The servers should be updated frequently.
An algorithm to find out the misbehaving servers.
Prior request should be made to the CSP for manipulation.
Allocating the an agent for Supervising.
Providing a unique token for each client within the cloud.
Handling the unknown user under supervision.

INTRODUCTION
Here we introduce this cloud services through an online banking application
Compared to many of its predecessors which only provide binary results about the storage status across the distributed servers ,we propose this new system.
This new scheme further supports secure and efficient dynamic operation on Data block
Hence our system is highly efficient as we have provided the technology of token generation for secure login to avoid intruders

Conclusion
17In this Project, to achieve the assurance of cloud data integrity and availability and enforce the quality of Dependable cloud storage for the user’s.
We rely on the automated Homomorphic token generation for the cloud data security.
Also we have avoided the memory usage for each TPA allocated for each client by considering the admin himself as the TPA.
