Robust Fake Iris Detection

摘要

Among biometrics such as face, fingerprint, iris and voice recognition, iris recognition system has been in the limelight for high security applications. Until now, most researches have been studied for iris identification algorithm and iris camera system, etc. But, there has been little researched for fake iris (such as printed, photographed or artificial iris, etc) detection and its importance has been much emphasized, recently. To overcome the problems of previous fake iris detection researches, we propose the new method of checking the hippus movement (the dilation/contraction of pupil size) and the change of iris code in local iris area by visible light in this paper.
