The fingerprint sensor derives an electric output signal in accordance with the topographic relief of the finger under investigation. The sensor incorporates a contact body which is formed at least in part by a light-transparent elastic material. The contact body, preferably a flat sensor plate made of said elastic material and attached to a flat supporting plate, has a light receiving surface and a contact surface for receiving a contact pressure by the finger. Before an investigation process is started, the contact surface is smooth. By pressing the finger against the contact surface, the contact surface will attain a shape conforming to the fingerprint pattern of the finger. The sensor also incorporates a light source, a photodetector and an optical system. The light source obliquely passes light to the contact surface which reflects a light beam modulated in accordance with the fingerprint. The optical system passes the reflected light beam to the light sensitive area of the photodetector.

A beam (2) of collimated light is directed towards a printed circuit board (4). The light beam is displaced as reflected from a point of incidence in a path including surfaces having different heights above the printed circuit board when detected at an angle oblique to the surface. From the variation of displacement which is portional to height, the overall profile of the circuit board including components present thereon is determined along the path (56) or line (64) the beam is incident. Various photodetectors (14) are utilized and the addition of a ramp filter (58) enables a single cell integrating photodetector to provide an output intensity indicative of the displacement. An arrangement (FIG. 11) is presented for compensating for variations in surface reflectivity using normalization or feedback.

The present invention applies speech recognition technology to remote access, verification, and identification applications. Speech recognition is used to raise the security level of many types of transaction systems which previously had serious safety drawbacks, including: point of sale systems, home authorization systems, systems for establishing a call to a called party (including prison telephone systems), internet access systems, web site access systems, systems for obtaining access to protected computer networks, systems for accessing a restricted hyperlink, desktop computer security systems, and systems for gaining access to a networked server. A general speech recognition system using communication is also presented. Further, different types of speech recognition methodologies are useful with the present invention, such as “simple” security methods and systems, multi-tiered security methods and systems, conditional multi-tiered security methods and systems, and randomly prompted voice token methods and systems.
