<p>A biometric input device (54), system and method includes a biometric input device (54) having a scanning window (56) surrounded by a ridge (120) ensuring positive positioning of a biometric sample such as a thumb. The biometric input device (54) includes an optical assembly (80) having a prism (82) with a focusing lens (84) disposed on a side thereof and optionally integrally formed therewith. A biometric comparison method is provided for comparing data (300) from said biometric input device (54) with data from a database (347) using both directional image comparison (315) and clusterized minutia location (340) and direction comparison (350). A further system is provided for allowing access to computer functions based on the outcome of the comparison method.</p> |
