To securely introduce an effective third party auditor (TPA), the following requirements have to be met: 1) TPA should be able to efficiently audit the cloud data storage without the local copy of data, and should not introduce any additional on - line burden to the cloud user; 2) The third party auditing process should preserve user data priva cy
