AN OPTIMIZED SCHEME FOR ASSESSING INTEGRITY WITHIN AN AGILE CLOUD ECOSYSTEM

Abstract: Cloud Computing is regarded as the forthcoming architectural framework for IT enterprises. Unlike conventional solutions, which maintain stringent physical, logical, and personnel controls over IT services, Cloud Computing relocates application software and databases to expansive data centres, where the management of data and services may lack complete reliability. Through cloud computing and storage, users gain the ability to access and share resources provided by cloud service providers at a reduced marginal cost. Furthermore, with cloud computing and storage services, data is not only stored in the cloud but is also frequently shared among numerous users within a group. This project proposes an Operable Proof of Retrievability, a privacy-preserving auditing mechanism for shared data among large groups in the cloud. It employs signatures to generate verification information for shared data, enabling a third-party auditor to assess the accuracy of the shared data without disclosing the identity of the signer for each block. Ultimately, the proposed auditing scheme aims to facilitate efficient public auditing while safeguarding both identity and data privacy within cloud environments.
