Abstract
In a place where the personal authentication is requested, if there occurs an emergency, e.g., an authenticatee is forced to unlock a key under threat against the authenticatee's will, there is provided an urgency report system that has lowered both a danger of an authentication apparatus's false operation and a risk of being detected from those around the authenticatee. In the personal authentication technology based on a finger-vein authentication, the employment of the following methods makes it possible to enter a rescue mode and to issue an urgency report: Actively deforming the finger-vein pattern in captured image, pushing a switch, which becomes a trigger for starting the authentication, longer than a predetermined time, or using a rotational motion of the finger.
