Enhanced Privacy Preserving with Data Freshness by Accomplishing Traceability over Oruta

Abstract
Cloud is used not only for storing data, but also the stored data can be shared by multiple users. Due to this the integrity of cloud data is subject to doubt. Several mechanisms have been designed to support public auditing on shared data stored in the cloud. During auditing, the shared data is kept private from public verifiers, who are able to verify shared data integrity using ring signature without downloading or retrieving the entire file. Ring signature is used to compute verification metadata needed to audit the correctness of shared data. With this, the identity of the signer in shared data is kept private from public verifiers. In this paper, we propose a traceability mechanism that improves Data Privacy by achieving traceability and the data freshness(the cloud possess the latest version of shared data) is also proved while still preserving identity privacy.
