Abstract:
The face authentication device includes a plurality of collation means which distribute and store a plurality of face feature quantities corresponding to a plurality of faces based on values of shard keys, an acquisition means, a shard key calculation means, and an authentication means. The acquisition means acquires an input face image. The shard key calculation means extracts a plurality of line segments, each defined by feature points of a face, from the input face image and calculates a ratio of the plurality of line segments as the shard key. The authentication means performs authentication of the input face image using the collation means corresponding to the value of the calculated shard key.
