摘要：Cloud Data Storage is an attractive mean for storing and managing the outsourced data. As data are remotely stored, user is not aware of any security threat. Data modification can done by the untrusted server , unauthorized user or by some malicious activity. So user needs to be ensured that their data are intact. For this various integrity checking techniques for cloud data storage have been proposed. This paper presents an approach for checking the integrity of remotely stored data on cloud. It also uses mechanism to recover the data if integrity is violated. Proposed approach uses the metadata of constant size. It stores the metadata as the metadata of file adversary cannot access it. As file size of uploaded file is same as the original file results less communication overhead.
