Abstract:
1. A method of user identification by hand imaging, comprising the steps of: a) placing the hand of a user within a space having at least a first sensor and at least a second sensor for imaging the hand of the user; b) the user stationary posing the hand in at least one hand sign; c) simultaneously imaging the hand of the user with at least said first sensor and said second sensor to produce, for each said hand sign stationary posed by the user, at least a first image of said hand sign and at least a second image of said hand sign; d) for each said at least first image and each said at least second image, conducting a pixel contrast value analysis of that image to independently produce for that image a numerical pixel contrast value based on the specific hand sign of that image; e) deriving a numerical digital signature capable of identifying the user to a statistical certainty having a series of said independently produced numerical pixel contrast values based on the sequence in which the user stationary posed the hand in at least one hand sign; f) increasing accuracy and differentiation of said numerical digital signature by utilizing at least two said independently produced numerical pixel contrast values for each hand sign corresponding to said at least first image and said at least second image of said hand sign; g) minimizing size requirements for records with said numerical pixel contrast values and said numerical digital signature; h) forming a baseline record identifying the user from said numerical digital signature.
