Acknowledgement Verification of Stored Data in Shared Cloud Resource Pool

Even if CU jealously envies the public data auditing task of stored data to a trustworthy third-party auditor to prevent communication costs as well as computing costs after data outsourcing. Practically speaking, neither TPA nor CSP can be trusted. Data may be deleted by CSPs in order to clear up storage space for financial gain or in order to protect their own reputation among cloud consumers by fabricating data loss instances. Since they do not have physical control over the outsourced data, cloud users are unable to identify the person claiming responsibility for unlawful data treatment. Internal security risks and risks to shared cloud storage still exist. On the other hand, TPA errs on occasion and acts deliberately or is the victim of other illegal activities. As a result, either the audit message might be spoofed or TPA could create a misleading audit message without performing any data verification work, in which case CSP would be up against it. In this study, we provide an innovative acknowledgment verification scheme for cloud storage services to resolve these challenging issues.
