AN AUTHORIZED PUBLIC AUDITING SCHEME FOR CLOUD STORAGE

Abstract

In today’s data-centric environment, cloud storage security is paramount. This paper presents a new public audit scheme with the ability to use ring signatures to facilitate the public audit of shared data while preserving signer privacy for individual blocks. Additionally, the system enables multiple audit projects to be supported simultaneously and simplifies the batch audit process, thereby greatly increasing overall efficiency Our ongoing research efforts are focused on enabling traceability in 2010, and empower unit administrators to designate signatories in specific circumstances using verification information. This policy represents an important step in strengthening cloud storage security while maintaining user privacy and usability.
