Iris Based De-duplication Technology

Iris recognition is the most accurate of the top three biometrics: fingerprints, facial recognition, and iris recognition. Iris recognition has a false accept rate of 1 in 1.2 million for one eye (1 in 1.44 trillion for two eyes) regardless of database size [1]. Iris recognition is the easiest one among biometrics related with the eye. It works with simple CCD camera and does not need direct contact between user and capturer. In addition, it has pattern comparison potential over the average the human iris is an annular region between the black pupil and the white sclera. Irises reveal rich and complex features and differ from human to human. Even, right and left irises are different from each other; this situation is also valid for twins. The iris begins to form in the third month of gestation and structures creating its pattern are largely complete by the eighth month, although pigment accretion can continue until two years old age. After two year-old age, there is no change in iris features through whole life. The iris has the great mathematical advantage that its pattern reliability among different persons is enormous in comparison with other biometrics. The Iris of a person is stable throughout a person’s life (From the age of two year till death); the physical characteristics of the Iris do not change with age, diseases or environmental conditions. Hence one time enrolment is enough for a person during his lifetime. Keywords— Iris, hamming distance, iriscode, Deduplication.FAR,FRR.
