Abstract

Many users currently store their files on many clouds, and it is not unusual for large amounts of data to be moved across clouds. It is possible that during the storage and transfer procedures, user files will get corrupted. This is because servers and cloud providers are not entirely reliable. Integrity verification must therefore be done, and it is best to spend as little time as possible on the process. The current techniques for demonstrating data migration still suffer with the issue of a large time overhead factor when it comes to large-scale file migrations. The authors of this article proposed a hierarchical proven data migration strategy to handle this problem. This method may be able to transfer a large number of continuous files between clouds while providing the efficacy of data transmission integrity authentication. This study offers a thorough explanation of the suggested approach along with an assessment of the security analysis's effectiveness. It was shown in light of the results that the proposed approach might significantly lower the detection latency of file transfers between clouds.
