Cloud is a place where we can store a huge amount of data and access them across multiple users. This leads two major problems such as "security" and "privacy". Many mechanisms has been designed toallow both data owners and public verifiers who are alsocalled as Third Party Auditors (TPA) to efficiently audit the integrity of data in cloud without retrieving the entire data from the server. Public or TP auditing on the integrated data may reveal the confidential information. The proposed system uses a novel privacy-preserving mechanism called ORUTA (One Ring to Rule Them All) support public auditing on shared data in the cloud and also exploits ring signatures to compute verification metadata (signature) needed to audit the correctness of shared data. The main scope of this project is to provide multiple auditing tasks simultaneously instead of verifying one by one.
