1. Apparatus for characterizing an individual based upon the spacing of at least two preselected lines on a human palm, comprisingscanning probe means translatable with respect to a scan line and in contact with a surface of said palm;
- said scanning probe means including transducer means for generating output signals representative of the pattern of skin lines along said scan line; and
transducer means responsive to the movement of said scanning probe means normal to said scan line for generating output signals representative of the gross surface profile of the palm along said scan line.

Abstract
A palm print identification system including a scanning probe translatable in contact with a human palm along a scan line. The probe may comprise one or more roller or drag probes, including light illumination and photodector means arranged to generate electrical signals representative of the pattern of palm lines. The spacing of palm lines as thus sensed is compared with a master read from an I.D. card or stored in a computer for I.D. verification.

10. Apparatus for identifying an individual based upon the spacing of at least two preselected lines on a human palm, comprising:
-
internal reflection head means translatable with respect to the surface of said palm for contact traversing a scan line; registration means for registering the palm with respect to said scan line; a source of light illuminating said head means at the area of contact with said surface of said palm; photodetector means responsive to light reflected from said surface of said palm through said head means for providing an output signal representative of the palm line pattern; means for storing a comparison signal representative of a known individual; and means for comparing said output signal and said comparison signal to test the identity of the individual presenting said palm. - View Dependent Claims (11)
