The only characteristic that is dependent on genetics is the pigmentation of the iris, which determines its color.
In 1993, John gave the idea of using iris for recognition. He described that iris recognition system has five main components: acquisition unit, segmentation unit, quality estimation unit, feature extraction unit, and matching of extracted feature of iris.
The advancement of technology has dramatically impacted iris recognition systems, providing the opportunity to create smaller, more portable autonomous systems.
High security areas use iris recognition systems. The current deployment of iris recognition systems ranges from government to industrial to even private use.
The systems are quite expensive and are used by government security organization, the military and financial institutions that deal with highly sensitive data.
Other uses are automated international border crossing, airport and aviation security, database and computer access, hospital access and countless other private industrial settings.
