Eye vein verification Eye vein verification Eye vein verification is a method of biometric authentication that applies pattern-recognition techniques to video images of the veins in a user's eyes. 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
Eye bank diseases such as HIV, hepatitis B, hepatitis C, human cytomegalovirus, syphilis, and sometimes others. The blood type is also tested, although corneas do not receive any blood supply and match typing is not necessary for transplantation. If the entire eye is enucleated during the original recovery, then the cornea and part of the sclera are removed and placed in a container with preservation medium, and the sclera is cleaned and then preserved in alcohol. The corneas are visually examined and evaluated underneath a slit-lamp, and the number of endothelial cells are counted underneath a specular microscope. The Eye Bank Association
