A new fake iris detection method based on 3D feature of iris pattern is proposed. In pervious researches, they did not
consider 3D structure of iris pattern, but only used 2D features of iris image. However, in our method, by using four
near infra-red (NIR) illuminators attached on the left and right sides of iris camera, we could obtain the iris image in
which the 3D structure of iris pattern could be shown distinctively. Based on that, we could determine the live or fake
iris by wavelet analysis of the 3D feature of iris pattern. Experimental result showed that the Equal Error Rate (EER) of
determining the live or fake iris was 0.33%.
