Trusted Third Party Auditing to Improve the Cloud Storage Security

Introduction of cloud storage service has made the users to access their data anywhere anytime without any trouble. Available systems that provide support for the remote data integrity are useful for quality of service testing but do not deal with server failure or handling misbehaving servers. The security issues that prevail in the data storage at cloud cause lot of threats to the users and cloud service providers. Available systems that provide support for the remote data integrity are useful for quality of service testing but do not deal with server failures or handling misbehaving servers. The proposed system ensures storage integrity and achieves strong cloud storage security with fast data error localization through the results provided by the auditing mechanism that is carried out by the third party auditor. Third party auditor carries out the public auditing in-order to maintain the integrity for the outsourced data that is present in cloud storage. Data integrity in ensured with the help of verification key along with erasure coded data, it also allows in handling the storage correctness and identification of misbehaving cloud server. The Audit Protocol Blocker is introduced in order to monitor the correctness of the Third Party Auditor by preventing the TPA from misusing the privileges that are provided to them by the cloud server.
