Person`s identification and verification method, involves consulting brightness values of iris for differentiation between back and connective tissue structures in order to skeletonize image of structures subsequently

The method involves converting structure of iris into specification of the structure. Brightness values of the iris are consulted for differentiation between back and connective tissue structures in order to skeletonize the image of the structures subsequently. A corner of an eye is horizontally defined, and a polar coordinates system is defined for measurement of the iris through a center of a pupil. Representation of the data is independent of a current size of the pupil. The connective tissue structure forms out between the iris and cornea.
