Abstract :

In this system we 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. This Project Mainly Focus To Realize The Authentication For The Data Acess On A Demand Mode. New Security And The Privacy Concerns Can Be Performed. AIDA Algorithm Is Used For The Multiparty Oriented Cloud Services. SAPA Protocol For Address The Privacy Issue.
