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.
