A LITERATURE SURVEY ON A NOVEL PRIVACY PRESERVING PUBLIC AUDITING MECHANISM ON SHARED CLOUD DATA USING ORUTA
Priyanga M. A · 2014
Abstract: In Cloud Computing Public auditing on the integrity of shared data is very big issue, because the public auditing scheme will predictably reveal confidential information, and identity privacy to public verifiers. This survey, propose a new scheme called a novel privacy-preserving mechanism which supports public auditing on shared data stored in the cloud. In particular, this scheme takes advantage of ring signatures to compute verification metadata. The ring signature scheme is needed to audit the correctness of shared data. With this mechanism, the identity of the signer on each block in shared data is kept secret or private from public verifiers. Public verifiers are one who are able to efficiently verify shared data integrity without retrieving the entire file. In addition, this mechanism is able to perform multiple auditing tasks simultaneously instead of single auditing task. This survey shows the effectiveness and efficiency of our mechanism when auditing shared data integrity. Key Words—Public auditing, privacy-preserving, shared data, cloud computing
