1. A method of employing an electronically controlled data processor for determining whether a currently processed person under examination should be extended a privilege granted by society comprising the steps of:

  • (a) inserting refined biometric signatures of numerous approved applicants for said privilege within said electronically controlled data processor;

    (b) producing a currently processed refined biometric signature of a current applicant for said privilege;

    (c) comparing said currently processed refined biometric signature of said current applicant for said privilege with refined biometric signatures of approved applicants stored within said data processor;

    (d) producing close match signals upon the production of a close match of said currently processed refined biometric signature with refined biometric signatures stored within said data processor;

    (e) producing tentative applicant reject signals in response to the production of said positive close match signals;

    (f) generating human recognizable representations of those closely matched refined biometric signatures which produced said tentative application reject signals for enabling comparison by a human being, thereby to tend to eliminate the effect of false positive match signals which tend to increase with large data banks, and which could result in an erroneous withholding of a privilege which could be otherwise extended to said applicant;

    (g) producing a coarse biometric index for each approved applicant, said coarse biometric index being indicative of different types of coarse biometric characteristics;

    (h) inserting coarse biometric indexes of approved applicants into said data processor;

    (i) comparing a coarse biometric index of a current applicant with numerous coarse biometric indexes of approved applicants stored within said data bank;

    (j) producing a negative comparison signal upon a mismatch resulting from executing step (i);

    (k) omitting steps (c)-(f) in response to the production of said negative comparison signal, thereby to save substantial processing labor which would otherwise be required; and

    (l) wherein the coarse biometric indexes compared in accordance with step (i) are representations of a plurality of different types of coarse biometric characteristics of persons matched, at least some of which are selected from the group consisting of sex, age, eye color, hair color, complexion, height, weight, facial feature parameters, slant of handwriting and handwriting readability.
