Patent ID: 7391890

Claim:
A method of identifying an individual using biometric data comprising the steps of (i) enrolling biometric data of the individual, wherein said biometric data includes data obtained from more than one biometric data of the same individual, and wherein said biometric data is selected from one or more of the following: finger print, palm print, iris or any other biometric data; (ii) identifying anchor features and all other identifiable significant features, wherein the anchor features consist of: (a) center point in finger prints or palm prints; (b) optic discs in retina image; or (c) lens section in iris image; wherein the significant features consist of: (a) ridge join points, ridge line endings for finger prints or palm prints; or (b) macula and vessel density in retina, and lens and iris portion in iris image; (iii) computing relativity in position of each significant feature in relation to the other feature, wherein the relativity includes distance or direction or both, and wherein the distance is expressed in number of ridges between the anchor feature and the significant feature; (iv) combining the relativity as computed in the step (iii) to obtain a classification code; (v) encrypting the classification code obtained in the step (iv) and the biometric data obtained in the step (i); (vi) storing the encrypted data obtained in the step (v); (vii) repeating the steps (i), (ii), (iii), (iv), (v) and (vi) for a biometric data of a person to be identified, wherein in the step (i) enrolling is replaced with capturing; and (viii) matching the classification code obtained in the step (vii) against the classification code obtained in the step (iv), wherein the matching step includes checking an absolute equality of the classification code.
