Cloud structure delivers infrastructure, platform and software as a service which are made available in pay-as-you go model. Cloud storage is a model of networked online storage where data is stored in virtualized pools of storage which are generally hosted by third parties. Users interact with the cloud servers through Cloud Storage Providers (CSP) to access or retrieve the data. Users have no time to monitor the data online. Hence, it entrust the auditing task to an optional Third Party Auditor (TPA). Its main aim is to achieve the integration of storage correctness across multiple servers and data error localization. Homomorphic pre computation is used in this paper to identify the error corruption.
