Abstract:
A method of detecting a venous network in a portion of a human body, the method comprising the steps of capturing an infrared image of said human body portion in order to reveal a venous network of said human body portion; analyzing contrast in the infrared image in order to determine contrast characteristics of the infrared image; and determining whether the human body portion is real on the basis of contrast characteristics determined in the infrared image and of contrast characteristics determined from reference human body portions. A method of biometric recognition with a prior stage of detecting whether a portion of a human body is real.
