Everything you want to know and more about iris recognition by its inventor, John Daugman:

  • Les francophones consulteront la thèse de Christel-Loïc TISSE:

  • Iris recognition has got its famous case with the afghan woman on the National Geographic cover who has been identified thanks to her green eyes.
    Voici le cas bien connu de l'Afghane aux yeux verts dont l'identité a été confirmée grâce à la reconnaissance de l'iris.

    Iris recognition uses iris images captured in the near infrared bandwidth. The iris color is not used, this is rather the iris structure which is recognized.
    La reconnaissance de l'iris nécessite de capturer une image dans le proche infrarouge (invisible). La couleur de l'iris n'est pas utilisée, c'est plutôt son relief qui est reconnu.

    heterochromia iridium David Bowie

    Heterochromia iridium (differing iris colors) and heterochromia iridis (a variety of color within a single iris) are relatively rare in humans and result from increased or decreased pigmentation of the iris. Most cases are the result of an alteration in the expression of the EYCL3 gene (which codes for brown/blue eye color) and EYCL1 (which codes for green/blue eye color), among other genes within the cells of the entire iris or even a particular section. Other potential causes include trauma around the time of birth or later in life, congenital pigmented nevi or even medications such as those used in the treatment of glaucoma.
    David Bowie's eyes are in fact of the same color - his pupils are of a different size because one is permanently dilated after a fight with a schoolfriend. It doesn't help for iris recognition, sure.


    Previous links already give most answers, but I give here some details about some specific questions.
    Les liens précédents répondent à la plupart des questions que vous pourriez vous posez, mais dans certains cas, j'ai voulu apporter ma contribution.

  • Iris recognition is extremely accurate (and much more better than fingerprints).
    La reconnaissance par iris est très précise (et bien mieux que les empreintes).
  • Twins have identical biometric traits (identical fingerprints, irises...). This is the same for clones.
    Les jumeaux sont identiques: mêmes empreintes digitales, même iris... C'est pareil pour les clones.
  • Biometric systems are able to detect diseases.
    On peut détecter des maladies avec les systèmes biométriques.
  • Iris or retina identification uses a (dangerous) laser.
    L'identification de l'iris ou de la retine utilise un (dangeureux) laser.
  • Iris recognition uses the color of the eyes, and cannot work with africans having very dark eyes.
    La reconnaissance de l'iris utilise la couleur des yeux, et ne marche pas avec les africains ayant les yeux très sombres.
