An anti-fake iris authentication mechanism for smart glasses

Wearable devices, especially the smart glasses, are gaining growing attention from both academy and industry. However, the smart glasses are suffering from the lack of a safety user authentication method. In this paper, an anti-fake iris authentication mechanism is proposed. The iris recognition method combined with the consistency detection of pupil size change is used in our mechanism to ensure its robustness to fake iris attacks as well as its potential to be deployed on small devices constrained by energy and hardware. Through experiment, the effectiveness of the proposed mechanism is shown.
