1. A method of identifying an individual from examination of their natural physical characteristics, the method comprising:

  • a. obtaining from an individual during a registration process, a fingerprint image having at least one registration pore and at least one registration macrofeature;

    wherein registration pore data is derived from the registration pores, and registration macrofeature data is derived from the registration macrofeatures;

    b. obtaining from an individual during a bid step, a fingerprint image having at least one bid pore and at least one bid macrofeature;

    wherein bid pore data is derived from the bid pores and bid macrofeature data is derived from the bid macrofeatures;

    c. constructing bid associated data derived from associating the bid pore data with the bid macrofeature data, and constructing registration associated data derived from associating the registration pore data with the registration macrofeature data;

    d. comparing the bid associated data to the registration associated data to produce a correlation score;

    arriving at a successful or failed identification result based on comparison of the correlation score to a predetermined threshold value.
