A spoofing detection apparatus comprising: a face image obtaining unit configured to obtain, from an image capture apparatus, a first image frame that includes a face of a subject person when light was emitted from a light-emitting apparatus associated with the image capture apparatus and a second image frame that includes the face of the subject person when the light-emitting apparatus was turned off; a face information extraction unit configured to extract information specifying a face portion of the subject person as first face information, from the first image frame, and extract information specifying a face portion of the subject person as second face information, from the second image frame; a feature calculation unit configured to extract a portion that includes a bright point formed by reflection in a first iris region of an eye of the subject person, from the first image frame, based on the first face information, also extract a second iris region corresponding to the portion that includes the bright point, from the second image frame, based on the second face information, obtains a luminance value L in of each pixel of the first iris region and a luminance value L out of each pixel of the second iris region, and calculates the difference between these values (L in - L out ) as a temporary feature, for each pixel, calculate a feature that is independent of a position of the bright point by converting the temporary feature into a one-dimensional vector and sorting the values in the one-dimensional vector in ascending order or descending order, wherein the sorted vector is the feature that is independent of a position of the bright point; and a spoofing determination unit configured to determine authenticity of the subject person captured by the image capture apparatus, based on the feature that is independent of a position of the bright point. a face image obtaining unit configured to obtain, from an image capture apparatus, a first image frame that includes a face of a subject person when light was emitted from a light-emitting apparatus associated with the image capture apparatus and a second image frame that includes the face of the subject person when the light-emitting apparatus was turned off; a face information extraction unit configured to extract information specifying a face portion of the subject person as first face information, from the first image frame, and extract information specifying a face portion of the subject person as second face information, from the second image frame; a feature calculation unit configured to extract a portion that includes a bright point formed by reflection in a first iris region of an eye of the subject person, from the first image frame, based on the first face information, also extract a second iris region corresponding to the portion that includes the bright point, from the second image frame, based on the second face information, obtains a luminance value L in of each pixel of the first iris region and a luminance value L out of each pixel of the second iris region, and calculates the difference between these values (L in - L out ) as a temporary feature, for each pixel, calculate a feature that is independent of a position of the bright point by converting the temporary feature into a one-dimensional vector and sorting the values in the one-dimensional vector in ascending order or descending order, wherein the sorted vector is the feature that is independent of a position of the bright point; and a spoofing determination unit configured to determine authenticity of the subject person captured by the image capture apparatus, based on the feature that is independent of a position of the bright point. <EOS>
