Iris recognition biometric systems apply mathematical pattern-recognition techniques to images of the irises of an individual's eyes.. Iris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on video images of one or both of the irises of an individual's eyes, whose complex patterns are unique, stable, and can be seen from some ...
Besides fingerprint and facial recognition, eye scanning is one of the most highly mentioned biometric modalities these days. As the security market rapidly increases, it is expected that eye ...

The Reds", species Iris fulva and Iris nelsonii, typically have red-orange corollas, with rare yellow forms. [1] Between 1920s and 1930s, Dr. John K. Small extensively studied irises in both Florida and Louisiana and named over 80 new species, including Iris savannarum, Iris kimballiae, Iris albispiritus and Iris rivularis. [2]
The features of the iris are one of the most stable features on the human body throughout life. [5] [disputed – discuss] The stability of iris structures is the foundation of the biometric technology which uses iris recognition for identification purposes. [6] [7]
The idea for retinal identification was first conceived by Carleton Simon and Isadore Goldstein and was published in the New York State Journal of Medicine in 1935. [5] The idea was ahead of its time, but once technology caught up, the concept for a retinal scanning device emerged in 1975.
The iris consists of two layers: the front pigmented fibrovascular layer known as a stroma and, behind the stroma, pigmented epithelial cells.. The stroma is connected to a sphincter muscle (sphincter pupillae), which contracts the pupil in a circular motion, and a set of dilator muscles (dilator pupillae), which pull the iris radially to enlarge the pupil, pulling it in folds.
Aran Safir (March 29, 1926 – January 21, 2007) was an American ophthalmologist and inventor. He is known for inventing a groundbreaking iris recognition scanner. This technology has been widely adopted in the security sector, ranging from the U.S. Department of Homeland Security to Google. [1]
