2. 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.

3. Existing System
 Replication based file distribution system.
 Third party auditing.
 Finding out Byzantine error and correcting them.

4. Proposed 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 an agent for Supervising.
 Providing a unique token for each client within the cloud.
 Handling the unknown user under supervision.
