Iris biometrics

Human identification that uses iris biometrics is based on individual pattern of human iris

Iris

Iris is pigmented internal organ of the eye that regulates quantity of the light pervading to the eye. Every iris has unique pattern, which is created by its tissues (mainly muscle fibre, pigment and ligaments). We could recognize some typical structures - pigment spots, radial and concentric furrows, crypts etc. These structures form individual pattern of every person, it could be used with very high accuracy for human identification.

History of method

1880 - criminalist Albert Bertillon was first who described and tried to realize idea of human identification based on iris biometrics
1987 - ophthalmologists Aran Safir a Leonard Flom patented idea of human identification based on iris biometrics
1994 - John Daugman made and patented first algorithms for human identification based on iris biometrics. This is the base for all identification systems of this type, today

Method

Iris is scanned by special optical scanning mechanism. Pattern of iris is transformed to "iris code", which is compared with relevant database.
