Abstract:
1. A contactless hand recognition system for identifying an individual, comprising: an imaging device producing an image signal of a person's hand; a computer-processing unit; an image processing unit contained in said computer-processing unit, connected to said imaging device for receiving said image of a person's hand based on measurable biometrics characteristics of said hand with the image comprising at least one of: (i) finger dimensions, (ii) palm dimensions, (iii) location of visible features on hand, (iv) location of thermal features of the hand, and (v) entire hand; a software program within said image processing unit that extracts said persons hand image from said imaging device; a minutia generator that processes said extracted hand image to generate minutia points; a software program to convert the minutia to a biometric template using a mathematical relationship between said minutia points; a database of individual records containing biometric templates; a biometric template match system that compares and computes a percentage of match between said video image biometric template and said biometric template from said database; an output signal which is produced when said match percentage exceeds a set threshold or a different output signal when said match does not exceed said set threshold; a token that presents a unique identification number wherein said token's communication media comprises at least one of: (i) radio frequency, (ii) laser, (iii) light, (iv) infrared, (v) acoustics, and (vi) mechanical contact; the hand recognition system further comprising said person's hand in a unique hand position, wherein said unique hand position matching results in multiple unique verifications with different meanings.
