1. A method for uniquely identifying a subject based on an iris image of an eye of the subject, comprising:

  • obtaining the iris image;

    applying at least one filter to the iris image to produce a filtered iris image, wherein said at least one filter enhances discriminative features of the iris image; and

    applying at least one encoding process to the filtered iris image to produce the iris code, wherein said at least one encoding process analyzes an intensity value for pixels in the filtered iris image,wherein the iris code uniquely identifies the subject.
