Abstract
A candidate face image and attribute information of each imaging attribute item are acquired. For each imaging attribute item, attribute information is extracted from a database that stores attribute information that has a degree of participation in false authentication greater than a participation degree threshold, among attribute information of analyzed imaging attribute items of analyzed master face images that resulted in false authentication in face image authentication. For each imaging attribute item, whether or not the extracted attribute information has a similarity to the acquired attribute information of the each imaging attribute item greater than a similarity threshold is determined. For each imaging attribute item for which the similarity is greater than the similarity threshold, a weight is assigned. A total score is calculated by summing the weights. When the total score satisfies a predetermined threshold value, the candidate face image is determined as inappropriate as a master face image.
