| Abstract |
Iris presentation attack detection (PAD) technology plays an important role in enhancing the security of access control systems that use iris recognition among biometric access authentication facilities. This study examines a fake iris recognition defense system that provides a strong defense against fake iris recognition attacks. Accurate pupil region detection through preprocessing is required to reduce errors when implementing PAD for identifying a fake iris. Iris PAD was designed to analyze whether instructions were implemented according to random blink attempts by an administrator and to determine the number of blinks and the presence or absence of the pupil in a given period. In a simulation, the pupil region of the iris of 100 was accurately detected in an external light environment. The experimental results showed that the proposed method accurately detected a fake iris. |
