Iris Eye Identification

Iris Recognition as Biometric Identification

Future of Iris Recognition, a form of Biometric Identification

Engineers perfect Iris Recognition, a form of biometric identification, in order to improve identification of personnel and security. Engineers use mathematical pattern-recognition techniques to automate Iris Identification. They take video images of one or both of the of an individual’s irises. Because complex patterns are unique, stable, and viewable from some distance, Engineers implement them in biometric identification.

Engineers show that Retinal scanning is an effective form of biometric identification. Many often confuse retinal scanning with iris recognition. But, retinal scanning uses the unique patterns on a person’s retina blood vessels unlike iris recgnition. However, iris recognition uses video camera technology with subtle near infrared illumination, acquiring images of the detail-rich, intricate structures of the iris. Each person manifests different Iris digital patterns.

Iris Identification as a from of Biometric Identification

Countries around the world enrolled several hundred million persons in iris recognition systems. To assist as passport-free automated border-crossings and some national ID programs. Engineers show key advantage of iris recognition, besides its speed of matching and its extreme resistance to false matches. The stability of the iris is internal and protected, yet externally visible organ of the eye.

Early American Ophthalmologist Proposed Iris Recognition

In the 1980s, two American ophthalmologists, L. Flom and Aran Safir, maintainded that the iris could serve as a human identifier. However, because they had no actual algorithm or implementation to perform it, their patent remained conjecture.  Engineers helped with various improvements over the years. These algorithms remain today form the basis of all significant public deployments of iris recognition. Engineers research on many aspects of this technology and alternative methods have exploded. Due to the high level of academic activity is this area make for a rapidly growing body of academic literature on the genetic aspects of this technology.    

Flagship Deployments of Iris Identification as a from of Biometric Identification

Engineers say 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 Amsterdam’s Schiphol Airport and at ten UK airport terminals allowing frequent travelers to present their iris instead of their passport.  In a program called IRIS: Iris Recognition Immigration System. Similar systems exist along the US/Canada Border, United Arab Emirates, all 32 air, land, and seaports deploy these algorithms to screen all persons entering the UAE requiring a visa.

The Government of India is enrolling the iris codes (as well as fingerprints) of one billion or more residents for national ID. As of April 2016 the UIDAI (Unique Identification Authority of India) had enrolled more than 1 billion persons in this biometric program. Iris is one of three identification technologies internationally standardized since 2006. This will be used in e-passports (the other two are fingerprint and face recognition).

Deployed Iris Recognition

Engineered deployed iris recognition systems acquire images of an iris while being illuminated by light in the near infrared wavelength band.   The majority of persons worldwide have “dark brown eyes”, the dominant phenotype of the human population. Thus, revealing less visible texture in the VW band. 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 illumination back into the iris camera.


Conclusion: Engineers researching Iris Identification could help make world security full proof, therefor, safer local and international travel and National Security for every country. A technique that cannot be easily changed from person to person.
