Abstract :
The importance of personal authentication is increasing with the development of the information society. The accuracy of personal authentication by identifying the iris is higher than that by using other biometric traits such as faces or fingerprints. However, the iris authentication system is vulnerable to deception by a fake iris even though the recognition accuracy is high. In this study, we developed a liveness detection method by using a variation in the brightness of an iris pattern induced by a pupillary reflex. The live and artificial irises were classified by a decision threshold of 7% brightness variation rate.
