The complex and random patterns are unique, and modern hardware and software can detect and differentiate those patterns at some distance from the eyes. The veins in the sclera—the white part of the eyes—can be imaged when a person glances to either side, providing four regions of patterns: one on each side of each eye. Verification employs digital templates from these patterns, and the templates are then encoded with mathematical and statistical algorithms. These
