Abstract:


Data integrity is among the important aspects for the clients to make full use of the benefits brought by the use of cloud computing. However, clients are worried of the protection of their dynamically changing data integrity because the administration of their data is controlled by cloud service providers. This paper proposes the implementation of the Proof of Retrievability (PoR) scheme for assuring data integrity on the cloud storage with dynamically changing data. The study uses experimental method to test cloud environment using a simulation tool. The method employed empirical data that were extracted from existing documents. It further provides the implementation design of dynamic PoR scheme as a solution to the data integrity problem. The developed cloud solution allows a client to challenge the server for the integrity of static and dynamic data, and improves cloud providers' security by enhancing services to the clients with assured data integrity.
