IRIS RECOGNITION

 

How does it work?

The idea of using iris patterns for personal identification was originally proposed in 1936 by ophthalmologist Frank Burch. In 1987 two ophthalmologists, Aran Safir and Leonard Flom, patented this idea, and in 1989 they asked John Daugman to try to create actual algorithms for iris recognition. These algorithms, which Daugman patented in 1994 are owned by Iridian Technologies/Securimetrics and are the basis for all current iris recognition systems and products.

Iris scans analyse the features in the coloured tissue surrounding the pupil which has more than 200 points that can be used for comparison, including rings, furrows and freckles. Iris technology combines computer vision, pattern recognition, statistical inference, and optics. Its purpose is real-time, high confidence recognition of a person's identity by mathematical analysis of the random patterns that are visible within the iris of an eye from some distance.

Because the iris is a protected internal organ whose random texture is stable throughout life, that one need not remember but can always present. The randomness of iris patterns has very high dimensionality; recognition decisions are made with confidence levels high enough to support rapid and reliable exhaustive searches through national-sized databases.

 

Current Applications

Major applications of this technology so far have been: substituting for passports (automated international border crossing); aviation security, and controlling access to restricted areas at airports; database access and computer login; access to buildings and homes; hospital settings, including mother-infant pairing in maternity wards; "watch list" database searching at border crossings; and other Government programmes.

 

Advantages of using Iris recognition

  • Perform 1:n identification with no limitation on numbers.
  • The most robust biometric technology available in the market today, never had a False Acceptance.
  • Biometric templates once captured do not need to be enrolled again, Iris stable through out a users life.
