A METHOD OF IDENTIFYING AN INDIVIDUAL USING BIOMETRIC DATA IS DISCLOSED COMPRISES OF A SEQUENCE OF STEPS. FIRST THE BIOMETRIC DATA OF THE INDIVIDUAL IS ENROLLED, SAID BIOMETRIC DATA SELECTED FROM ONE OR MORE OF THE FOLLOWING: FINGER PRINT, PALM PRINT, IRIS OR ANY OTHER BIOMETRIC DATA. THE ANCHOR FEATURES AND OTHER IDENTIFIABLE SIGNIFICANT FEATURES ARE IDENTIFIED. THE ANCHOR FEATURES CONSIST OF: CENTER POINT IN FINGERPRINTS OR PALM PRINTS, OPTIC DISCS IN RETINA IMAGE OR LENS SECTION IN IRIS IMAGE. THE OTHER IDENTIFIABLE SIGNIFICANT FEATURES INCLUDE: RIDGE JOIN POINTS, RIDGE LINE ENDINGS FOR FINGER PRINTS OR PALM PRINTS OR MACULA AND VESSEL DENSITY IN RETINA, AND LENS AND IRIS PORTION IN IRIS IMAGE. THE RELATIVITY OF EACH SIGNIFICANT FEATURE IN RELATION TO THE OTHER FEATURE IS COMPUTED. THE RELATIVITY INCLUDES DISTANCE OR DIRECTION OR BOTH. THE RELATIVITY IS COMBINED TO OBTAIN A CLASSIFICATION CODE. THE CLASSIFICATION CODE AND THE BIOMETRIC DATA OBTAINED ARE ENCRYPTED. THEN THE ENCRYPTED DATA IS STORED. SOME OF THE ABOVE STEPS ARE REPEATED IN THE PROCESS OF CAPTURING THE BIOMETRIC DATA OF A PERSON TO BE IDENTIFIED. THE CLASSIFICATION CODE IS MATCHED AGAINST THE EARLIER STORED CLASSIFICATION CODE. THE BIOMETRICS DATA IS VERIFIED AGAINST THE EARLIER STORED BIOMETRICS DATA OF THE SAME INDIVIDUAL.
