Efficient method to verify the integrity of data with supporting dynamic data in cloud computing

Dear editor, Cloud computing allows users to move local data to a server in the cloud to lighten the loads on their local storage. Because they no longer have physical possession of the data, it is very important to ensure the correctness and consistency of the outsourced data [1,2]. We herein use the Merkle Hash tree (MHT) [3] data structure and the Bloom filter [4] to achieve more effective data verification than previous methods. At the same time, our method can also support dynamic operations and public verification very well.
