Enhanced Security Framework for Data Integrity Using Third-party Auditing in the Cloud System

Cloud computing is an evolving paradigm that has been resulted as an adoption of available technologies. Although cloud technology allows users to take more benefits from available infrastructures, and virtualization, which is an enabling technology provided by the cloud allows users to manage and use the resources in an efficient and easiest manner, it does not guarantee data integrity and security over the resources stored in the cloud. Though many security frameworks have been developed for the cloud, still there may be loss of data or loss of control over data uploaded into the cloud. And also, many solutions for data integrity by third-party auditor are available but they are semi-trustable, if third-party auditors (TPA) compromise unauthorized access over the resource in the cloud. Hence, our proposed scheme focuses on extended framework that guarantees data integrity by involving data owner to perform auditing on the outsourced data in the cloud. And so, our proposed scheme achieves data integrity and guarantees security to the data owners for their resource in the cloud to major extent. Therefore, this type of TPA approach creates awareness to the data owner of their resource and thereby guarantees data integrity for every resources stored in the cloud.
