Privacy Preserving Public Aditing of Shared Data
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2020, Vol 4, Issue 3
Abstract
In this paper, we propose a novel privacy preserving mechanism that supports public auditing on shared data stored in the cloud 2 . Particularly, we exploit ring signatures to compute verification metadata needed to audit the correctness of shared data. Using our idea , of the signer on each block in shared data is kept private from all public verifiers, who are able to easily verify shared data integrity without getting the entire file. In addition, our mechanism is able to perform various auditing tasks at same time instead of verifying them one by one. The propose system, a privacy preserving public auditing mechanism for shared data in any source particularly cloud. We can use ring signatures to build homomorphism authenticators, so that a public verifier is able to perform auditing task shared data integrity without retrieving the entire data to improve efficiency further extend our mechanism to support batch auditing. There are two problems we will continue to study for our future work. One of them is traceability of data , which means the group manager can able to reveal the identity of the signer based on verification metadata in some special situations. Dr. H.
