Abstract:
1. An information device comprising: a fingerprint image capture section which captures a fingerprint image; a comparison section which compares a first fingerprint image captured by the fingerprint image capture section with a second fingerprint image captured by the fingerprint image capture section at a given time interval after the first fingerprint image is captured; an image generation section which generates an image based on the comparison result of the comparison section; a display section which displays the image generated by the image generation section; a minutiae point extraction section which extracts a minutiae point of at least the first fingerprint image; and a check section which checks the first fingerprint image with registration information which has been previously registered, wherein: the number of times a line segment connecting minutiae points of the first fingerprint image intersects a fingerprint ridge or a fingerprint valley of the first fingerprint image.
