Abstract

In this paper, we propose a new fake-iris detection method. In order to detect the fake-iris, we measure the change of the reflectance ratio between iris and sclera. In a live iris, the amount of change is relatively large compared to that in a fake-iris. From our experimental results, it is clear that our fake-iris detection method achieves high performance when distinguishing between a live-iris and a fake-iris.
