COLLATION DEVICE, COLLATION METHOD AND COLLATION PROGRAM

摘要

To provide a verification apparatus, a verification method, and a verification program capable of improving authentication accuracy.The verification apparatus includes: a similarity calculation unit that calculates a positional difference and a degree of similarity in feature value between each feature point in a verification image captured by an imaging device and each of a plurality of feature points in a registered image registered in advance; and a matching unit that matches the verification image against the registered image by using the degree of similarity to a feature point having the degree of similarity that is second highest or lower for each feature point in the registered image in a case where a positional difference from a feature point having the degree of similarity that is highest in the verification image is greater than a threshold value.
