Abstract
Low cost, high performance and on-demand access of cloud infrastructure facilitates individuals and organizations to outsource their high volume of data to cloud storage system. With continuously increasing demand of cloud storage, security of users’ data in cloud is becoming a great challenge. One of the security concerns is ensuring integrity of the data stored in the cloud, and trusted third-party based public auditing is a standard technique for cloud data authentication. In this paper, for the first time, we propose an auditing scheme for cloud data without requiring a third party. We exploit the block-chain data structure of Bitcoins to propose an auditing mechanism whereby any user can perform the validation of selected files efficiently. In case a user does not possess the required computational resource for verification, or a user is reluctant to do the verification, our scheme provides the option for third party verification as well, without any additional overhead of data structure, computation or storage.
