Abstract
The present invention relates to a method for detecting fraud in a biometric recognition system characterized in that it comprises the following steps: obtaining a first image of a subject's area of interest in a first wavelength band; obtaining a second image of the subject's area of interest in a second wavelength band; encoding the first image by a first neural encoder to obtain a first vector representation of the first image; encoding the second image by a second neural encoder to obtain a second vector representation of the second image; calculating a similarity measure between the first and second vector representations; and determining fraud if the similarity measure is less than a predefined threshold.
