dynamic audit services for integrity verification of outsourced storages in clouds dfd
Abstract: In this paper, we propose a dynamic audit service for verifying the integrity of untrusted and outsourced storage. Our audit service, constructed based on the techniques, fragment structure, random sampling and index-hash table, can support provable updates to
outsourced data, and timely abnormal detection. In addition, we propose an efficient approach based on probabilistic query and periodic verification for improving the performance of audit services. Our experimental results not only validate the effectiveness of our
approaches, but also show our audit system has a lower computation overhead, as well as a shorter extra storage for audit meta data.
