Cloud storage providers commonly engage in both data storage and data sharing operations, which involve storing data on the cloud and distributing it among several users. However, the issue remains regarding how to safeguard individuals' identities while simultaneously enabling public scrutiny of the shared data. This study presents a novel approach that ensures users' privacy while allowing transparent auditing of shared data stored in the cloud. To precisely calculate the verification data required for an audit of the integrity of the shared data, we utilize ring signatures. Our methodology enables a third-party auditor (TPA) to assess the integrity of published material without the need to download the entire file. This is achieved while maintaining the signer's privacy on each specific block. The test results demonstrate the efficacy of our proposed strategy in auditing shared data.
