Privacy Preservation and traceability support using Public Auditing Mechanism
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2015, Vol 3, Issue 12
Abstract
as future enhancement, we enhance the Oruta system in two interesting problems we will continue the study for our future work. One of them is traceability, which means the ability for the group manager (i.e., the original user) to reveal the identity of the signer based on verification metadata in some special situations.However, public auditing on the integrity of shared data with these existing mechanisms will inevitably reveal confidential information to identity the privacy to public verifiers. Since Oruta is based on the ring signatures, where the identity of the signer is unconditionally protected, the current design of ours does not support traceability. To the best of our knowledge, designing an efficient public auditing mechanism with the capabilities of preserving identity privacy and supporting traceability is still open. Another problem for our future work is how to prove data freshness (prove the cloud possesses the latest version of shared data) while still preserving identity privacy. In addition, our mechanism is able to perform multiple auditing tasks simultaneously instead of verifying them one by one. Our experimental results demonstrate the effectiveness and efficiency of our mechanism when auditing shared data integrity.
