通过使用云存储，用户可以随时通过互联网访问应用程序，服务和软件。用户可以将他们的数据远程存储到云存储，并从资源中获得按需服务和应用程序的好处。云必须确保用户数据的完整性和安全性。关于云存储的问题是用户数据的完整性和隐私性可能会出现。为了避免这个问题，我们提供了云存储的公共审计过程，用户可以使用第三方审计器（TPA）来检查数据的完整性。不仅验证数据的完整性，该系统还支持数据动态。在这方面所做的工作缺乏数据动态和真正的公共可解释性。审计任务监视数据修改、插入和删除。所提出的系统能够支持公共可验证性，数据动态和多个TPA用于审计过程。我们还将我们的概念扩展到使用HARS方案的环签名。Merkle Hash Tree用于改进块级认证。此外，我们扩展我们的结果，使TPA执行审计多个用户同时通过批审计。索引术语：云存储，数据动态，公共审计，隐私保护，环签名。
By using Cloud storage, users can access applications, services, software whenever they requires over the internet. Users can put their data remotely to cloud storage and get benefit of on-demand services and application from the resources. The cloud must have to ensure data integrity and security of data of user. The issue about cloud storage is integrity and privacy of data of user can arise. To maintain to overkill this issue here, we are giving public auditing process for cloud storage that users can make use of a third-party auditor (TPA) to check the integrity of data. Not only verification of data integrity, the proposed system also supports data dynamics. The work that has been done in this line lacks data dynamics and true public auditability. The auditing task monitors data modifications, insertions and deletions. The proposed system is capable of supporting public auditability, data dynamics and Multiple TPA are used for the auditing process. We also extend our concept to ring signatures in which HARS scheme is used. Merkle Hash Tree is used to improve block level authentication. Further we extend our result to enable the TPA to perform audits for multiple users simultaneously through Batch auditing.
