摘要： A computer acquires image data including a target object captured by a camera. The computer detects motions at each of a plurality of positions on a subject including the target object captured by the camera, based on the acquired image data. The computer specifies a plurality of the positions where magnitude of the detected motions is greater than a reference value, from among the plurality of positions on the subject. The computer performs evaluation as to the target object captured by the camera, based on distribution of the specified plurality of the positions on the image data. As a result, highly accurate forgery determination is enabled.

摘要： A biometric information processing apparatus includes: a biometric information acquiring unit which acquires a user's biometric information and generates a biometric input image representing the biometric information; and a processing unit. The processing unit implements the functions of: generating a first intermediate image by applying first image processing to the biometric input image; generating a second intermediate image by applying second image processing to the biometric input image, the second image processing being different from the first image processing; detecting, from each of the first and second intermediate images, a singular point candidate that is a point corresponding to a singular point characterizing the biometric information; calculating a distance between the singular point candidate detected from the first intermediate image and the singular point candidate detected from the second intermediate image for the same singular point contained in the biometric information; calculating a quality metric for the biometric input image in such a manner as to set the quality metric higher as the distance between the singular point candidates decreases, and judging whether or not the quality metric is higher than a predefined threshold value; and if the quality metric is not higher than the threshold value, then prompting the user to have the user's biometric information reacquired by the biometric information acquiring unit.
