Master face image registration apparatus, registration method, program, and recording medium

A master face image registration apparatus, comprising:

• an image information acquisition unit;
• a false authentication information extraction unit;
• a similarity determination unit;
• a score calculation unit;
• an aptitude determination unit;
• and
• an output unit, wherein
• the image information acquisition unit acquires a candidate face image and attribute information of an imaging attribute item related to imaging of the candidate face image in association with each other as candidate information of a master face image for face image authentication,
• the false authentication information extraction unit extracts attribute information on the same imaging attribute item as the candidate face image from a database that stores attribute information that is significantly participate in false authentication among attribute information of imaging attribute items of master face images resulting in false authentication in face image authentication,
• the similarity determination unit determines whether or not the extracted attribute information of the imaging attribute item is similar to the attribute information of the imaging attribute item of the master face image,
• when it is determined to be similar, the score calculation unit assigns a weight indicating a degree of participation in an occurrence of false authentication set for each imaging attribute item and calculates a total score by summing the weight for each imaging attribute,
• when the total score satisfies a predetermined threshold value, the aptitude determination unit determines that the candidate face image is inappropriate as a master face image, and
• when it is determined to be inappropriate, the output unit outputs a determination result indicating that the candidate face image is inappropriate as the master face image.
