Abstract
A sheet-shaped sensor is laid on the ground on which a person can walk in a barefoot state or a barefoot-equivalent state so as to allow it to come in contact with the soles of the right foot and left foot. A feature value acquisition unit derives a feature value based on a first point positioned in an inner side of a landing portion below a metatarsal bone of the right foot or left foot, a second point positioned in an outer side thereof, and a third point positioned at a landing portion below a calcaneus bone, based on an output of the sheet-shaped sensor generated when the person stands still on the sheet-shaped sensor or when the person is walking. An authentication unit authenticates the person based on the feature value.
Claims13
A biometric authentication apparatus comprising:
- a sheet-shaped sensor laid on ground on which a person can walk in a barefoot state or a barefoot-equivalent state so as to allow the sheet-shaped sensor to come in contact with soles of left and right feet;
- a feature value acquisition unit structured to acquire a feature value based on a first point positioned in an inner side of a ground-touching portion below a metatarsal bone of the right foot or the left foot, a second point positioned in an outer side thereof, and a third point positioned at a ground-touching portion below a calcaneus bone, based on an output of the sheet-shaped sensor generated when the person stands still on the sheet-shaped sensor or when the person is walking;
- and
- an authentication unit structured to authenticate the person based on the feature value.
