In this paper, we propose the way to discriminate between remnants and fingerprint images captured from optical fingerprint scanner by using frequency analysis. We can perfectly prevent the fingerprint verification device from malfunctioning caused by remnants, when strong flashlight or direct sunlight slant in optical scanner in a real world.
