Iris recognition biometric systems apply mathematical pattern recognition techniques to images of the irises of an individuals 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 individuals eyes, whose complex patterns are unique, stable, and can be seen from some distance. Retinal scanning is a different, ocular based biometric technology that uses the unique patterns on a persons retina blood vessels and is often confused with iris recognition. Iris recognition uses video camera technology with subtle near infrared illumination to acquire images of the detail rich, intricate structures of the iris which are visible externally. Digital templates encoded from these patterns by mathematical and statistical algorithms allow the identification of an individual or someone pretending to be that individual. Databases of enrolled templates are searched by matcher engines at speeds measured in the millions of templates per second per single core CPU, and with remarkably low false match rates. Several hundred million persons in several countries around the world have been enrolled in iris recognition systems for convenience purposes such as passport free automated border crossings and some national ID programs. A key advantage of iris recognition, besides its speed of matching and its extreme resistance to false matches, is the stability of the iris as an internal and protected, yet externally visible organ of the eye.

In a 1. 95. 3 clinical textbook, F. H. Adler2 wrote In fact, the markings of the iris are so distinctive that it has been proposed to use photographs as a means of identification, instead of fingerprints. Adler referred to comments by the British ophthalmologist J. H. Doggart,3 who in 1. Just as every human being has different fingerprints, so does the minute architecture of the iris exhibit variations in every subject examined. Its features represent a series of variable factors whose conceivable permutations and combinations are almost infinite. Later in the 1. American ophthalmologists, L. Flom and A. Safir managed to patent Adlers and Doggarts conjecture that the iris could serve as a human identifier, but they had no actual algorithm or implementation to perform it and so their patent remained conjecture. The roots of this conjecture stretch back even further in 1. Frenchman A. Bertillon had documented nuances in Tableau de liris humain. Divination of all sorts of things based on iris patterns goes back to ancient Egypt, to Chaldea in Babylonia, and to ancient Greece, as documented in stone inscriptions, painted ceramic artefacts, and the writings of Hippocrates. Iris divination persists today, as iridology. The core theoretical idea in Daugmans algorithms is that the failure of a test of statistical independence can be a very strong basis for pattern recognition, if there is sufficiently high entropy enough degrees of freedom of random variation among samples from different classes. In 1. 99. 4 he patented this basis for iris recognition and its underlying computer vision algorithms for image processing, feature extraction, and matching, and published them in a paper. These algorithms became widely licensed through a series of companies Iri. Scan a start up founded by Flom, Safir, and Daugman, Iridian, Sarnoff, Sensar, LG Iris, Panasonic, Oki, BI2, Iris.

With various improvements over the years, these algorithms remain today the basis of all significant public deployments of iris recognition, and they are consistently top performers in NIST tests implementations submitted by L 1, Morpho. Trust and Morpho, for whom Daugman serves as Chief Scientist for Iris Recognition. But research on many aspects of this technology and on alternative methods has exploded, and today there is a rapidly growing academic literature on optics, photonics, sensors, biology, genetics, ergonomics, interfaces, decision theory, coding, compression, protocol, security, mathematical and hardware aspects of this technology. Most flagship deployments of these algorithms have been at airports, in lieu of passport presentation, and for security screening using watch lists. In the early years of this century, major deployments began at Amsterdams Schiphol Airport and at ten UK airport terminals allowing frequent travellers to present their iris instead of their passport, in a programme called IRIS Iris Recognition Immigration System.

Because a large watch list compiled among GCC States is exhaustively searched each time, the number of iris cross comparisons climbed to 6.

Visible vs near infrared imagingeditAll publicly deployed iris recognition systems acquire images of an iris while being illuminated by light in the near infrared wavelength band NIR 7. The majority of persons worldwide have dark brown eyes, the dominant phenotype of the human population, revealing less visible texture in the VW band but appearing richly structured, like the cratered surface of the moon, in the NIR band. Some examples are shown here. Using the NIR spectrum also enables the blocking of corneal specular reflections from a bright ambient environment, by allowing only those NIR wavelengths from the narrow band illuminator back into the iris camera. Iris melanin, also known as chromophore, mainly consists of two distinct heterogeneous macromolecules, called eumelanin brownblack and pheomelanin yellowreddish,67 whose absorbance at longer wavelengths in the NIR spectrum is negligible. At shorter wavelengths within the VW spectrum, however, these chromophores are excited and can yield rich patterns. Hosseini, et al. 8 provide a comparison between these two imaging modalities. An alternative feature extraction method to encode VW iris images was also introduced, which may offer an alternative approach for multi modal biometric systems. Visible wavelength iris image. Near infrared NIR version. NIR imaging extracts structure. Visible light reveals rich pigmentation details of an Iris by exciting melanin, the main colouring component in the iris. Pigmentation of the iris is invisible at longer wavelengths in the NIR spectrum. Even dark brown eyes reveal rich iris texture in the NIR band, and most corneal specular reflections can be blocked.
