| dc.description.abstract | Data integrity is one of the vital aspect that could make stakeholders utilize fully the benefits brought by the use of cloud computing. Users concerns, like data integrity, on utilizing cloud storage arise because the administration of their data is under control of someone else. This research proposed the approach for implanting proof of retrievability (POR) scheme for assuring data integrity on the cloud storage with dynamically changing data. This study extracted empirical data from existing documents for the subject under investigation. It uses experimental method on testing cloud environment by the use of a simulation tool. The research provides the design on implementing dynamic proof of retrievability scheme as a solution to the data integrity problem. On ensuring integrity of dynamic data re-calculation of metadata was performed every time when data were modified. SHAI and MDS were used as hashing algorithm while creating metadata on the solution given. The developed solution assures data integrity by allowing a client to challenge the sever for the integrity of his/her static or dynamic data stored in a server Thus the implemented POR scheme on cloud storage has shown that it can ensure the integrity of both static and dynamic data files. With this solution, cloud providers can benefit from the improved security by enhancing their services to the clients with assured data integrity. Once the integrity has been ensured by the implementation of proof of retrievability users will be confident on utilizing the services | en_US |
