云计算是一种最新技术,通过互联网提供各种服务。云服务器允许用户在云存储数据,而不必担心数据的正确性和完整性。云数据存储在本地数据存储有很多优势。用户可以上传数据云,随时随地可以访问这些数据没有任何额外的负担。用户不需要担心云数据的存储和维护。但随着数据存储在远程位置用户可以确认如何存储数据。因此云数据存储应该有一些机制,将指定存储数据存储在云的正确性和完整性。云数据存储的主要问题是安全性。组织的日志记录存储在日志文件可能包含敏感数据应正确适当的工作组织的保护。维护安全的日志记录是最重要的任务之一。 Also, over a long period of time maintaining integrity of such log data is very important. However, deploying such a system for security of log records is an overhead for an organization and also itrequires additional cost. Many researchers have proposed their work or new algorithms for security of log records or to resolve this security problem. This study also reveals about consistency rationing and various adaptive policies. In this work, propose a novel privacy-preserving mechanism that supports public auditing on shared data stored in the cloud. In particular, we exploit ring signatures to compute verification metadata needed to audit the correctness of shared data. With our mechanism, the identity of the signer on each block in shared data is kept private from public verifiers, who are able to efficiently verify shared data integrity without retrieving the entire file. In addition, our mechanism is able to perform multiple auditing tasks simultaneously instead of verifying them one by one. Our experimental results demonstrate the effectiveness and efficiency of our mechanism when auditing shared data integrity.
