An Overlay Authentication Network for Active Utilization of Private Information

In this paper, we propose an overlay authentication network for active utilization of private information. The proposed network realizes safe registration and usage of users´ private information. In addition, the proposed network realizes the distributed management and utilization of users´ private information. These features enable services which utilize users´ private information. In this paper, we present implementation of the prototype system based on the proposed network, and confirm the effectiveness of the proposed network.
