Abstract:
1. A personal identification apparatus for measuring tactile pressures exerted by a person's hand and indicative of his identity, comprising: a pressure plate having a template of a human hand including a palm area and a plurality of elongated finger areas; a plurality of pressure sensors distributed on said plate and within said template such that more of said pressure sensors are positioned near a periphery of the palm area than near a center of the palm area, wherein each of the pressure sensors is operative to provide an output signal proportional to a pressure applied to said plate at the area at which said sensor is located, to enable said sensors to provide said output when a person's hand is emplaced on said plate to exert a pressure on said plate, storage means for storing pressure profile signals of enrolled persons requiring identification, and means for comparing said stored pressure profile with said output pressure signals to provide a favorable comparison when said output signals conform to said stored profile signals for positively identifying said person.
