Abstract:
A fingerprint matching apparatus includes a fingerprint distortion detection unit for detecting whether or not a correlation object intentionally distorts the finger put on the fingerprint reading face by, for example, applying excessively large force to the finger, or dragging or rolling the finger. With this configuration, it is possible to prevent a distorted fingerprint image from flowing into the fingerprint matching apparatus and therefore the probability of accurate fingerprint correlation can be increased.
