Abstract:

Cloud computing calculative is phenomenon which enable to access resources such as softwares, hardwares, and services over the global network. The main aim of user to store data on cloud to get security and integrity of data. Here the aim of this paper to ensuring the problem of data integrity & data security while keeping in cloud computing. TPA(Third Party Auditor) is used to expose different risks of cloud services to provide the  benefit to the cloud client. For the data security , we proposed a correcting code for the distribution of file for data dependability. After using homomorphic token with distributed verification of correcting coded data ,This approach achieve storage correctness and error localization. The security analysis shows the proposed approach is highly efficient and beneficial against  malicious data alternation attack and server colluding attacks.

Keywords: Cloud computing ,Data integrity & Security ,Third Party Auditor.
