Abstract: The invention relates to a method for identification on the basis of biometric data of an iris of an eye to be identified, including the steps of: encoding an image of the iris to be identified and a second iris image so as to obtain binary codes that are representative of the images to be compared; determining a binary similarity code from the binary code of the image of the iris to be identified and the second binary code of the second iris image; determining a confidence score on the basis of the local densities of similarities between the two compared iris images, as well as on the basis of the binary similarity code, the local similarity densities being in turn determined on the basis of the binary similarity code; and deciding, depending on the value of the confidence score, whether or not the two iris images are from the same iris. The invention also relates to a system suitable for implementing the identification method.
