A biometrics method based on a thermal image of a finger comprises acquiring the thermal image of the finger (S01) and extracting a finger-print image or a finger-vein image from the thermal image (S02). An equivalent biometrics system is also independently claimed. The method may further comprise comparing the finger-print image with a finger-print template, obtaining a first compared result, comparing the finger-vein image with a finger-vein template to obtain a second compared result, and verifying a user's identity according to one or both of the compared results. Template comparison steps can comprise extracting and comparing minutia points; graphic pattern comparison may be used. |
