Device and method for internally and externally assessing whitelists

A white list inside or outside determining apparatus comprising:

• a first feature data extracting unit which extracts first feature data from an image by using a first transformation formula created based on a plurality of preliminary learning images;
• a second feature data extracting unit which extracts second feature data from an image by using a second transformation formula created from the preliminary learning images and a plurality of application learning images;
• a first matching unit which performs matching between a registration image and a collation image by using the first transformation formula;
• and
• a second matching unit which performs matching between a registration image and a collation image by using the second transformation formula,
• wherein weights of a matching result of the first matching unit and a matching result of the second matching unit are changed according to the number of preliminary learning images and the number of application learning images.
