A Survey on Cloud Computing System Using Provable Multicopy with Dynamically Fragmented Data

Distributed data to a remote Cloud Service Provider is a flourishing trend for infinite customers and institution relieve the difficulty of local data storage and maintenance. Moreover the customer gets confidence on the data mirroring provided by the CSP. The structure used for data mirroring can be different based on the data; more facsimile(copies) are demanded for derogatory data which cannot quickly be reproduced This critical data should mirrored on multiple servers across multiple data centers. Before mirroring CSP split the data for improve the efficiency. The system aims the desire riskless and efficient protocol that conquers the limitations of the previous model. It will address the problem of creating multiple facsimile of data over the cloud server, and also review all these facsimile to verify the truthfulness.The Message Authentication Code based algorithm should be used for identifying the integrity and also provide security based on the Elliptic Curve Cryptography encryption and decryption schemes.
