The iris is a shaded, flimsy, roundabout structure of the eye which controls light entering the retina by regulating the diameter and size of the pupil. It doesn’t change its appearance over a range of an individual’s lifetime except if harmed by external components [5]. Hereditarily indistinguishable twins also have distinctive iris designs. The irises of two eyes of an individual are also unique. Iris recognition is an automated method of identifying unique intricate patterns of an individual’s iris using mathematical pattern-recognition techniques.

WORKING OF IRIS READERS

1 1. Scan an individual’s eyes with subtle infrared illumination to obtain detailed patterns of iris.

2 2. Isolate iris pattern from the rest of the picture, analyze, and put in a system of coordinates.

3 3. Coordinates are removed using computerized data and in this way an iris mark is produced.

Even on disclosure, one cannot restore or reproduce such encrypted iris signatures. Now the user just needs to look at the infrared camera for verification. Iris acknowledgment results in faster coordination and is extremely resistant to false matches.
