Abstract — With cloud information services, it is very common for information to be not only saved in the cloud, but also distributed across multiple users. Unfortunately, the reliability of cloud information is subject to uncertainty due to the lifestyle of hardware/software problems and human errors. Several systems have been designed to allow both information owners and public verifiers to effectively auditing cloud information integrity without accessing the whole information from the cloud server. However, public auditing on the reliability of distributed information with these existing mechanisms will certainly reveal private information—identity privacy—to public verifiers. This survey recommends a novel privacy-preserving procedure that facilitates public auditing on distributed information saved in the cloud. It manipulates ring signatures to estimate confirmation meta-data needed to audit the correctness of distributed information. With this procedure, the identification of the signer on each block in distributed information is kept private from public verifiers, who are able to effectively confirm distributed information reliability without retrieving the whole file. In addition, this procedure is able to perform several auditing projects at the same time instead of confirming them one by one. Our trial results illustrate the efficiency and usefulness of our procedure when auditing distributed information reliability.
