Biometrics-based identification method and apparatus

An identification apparatus comprising:

• a measurement arrangement arranged to measure a surface structure and an inner structure of a body member so as to obtain a surface-structure measurement result and an inner-structure measurement result, the measurement arrangement being arranged to measure the inner structure of the body member by a radiation that traverses the body member so as to obtain a transmission image of the body member, the measurement arrangement being further arranged to apply a further radiation to an object that should normally be the body member so as to obtain a verification image;
• a processor arranged to compare the surface-structure measurement result with an surface-structure reference result that distinguishes an individual from other individuals, and to compare the inner-structure measurement result with an inner-structure reference result that is associated with the same individual and that distinguishes the individual from other individuals, the processor being further arranged to compare the verification image with the transmission image of the body member so as to ascertain that the verification image represents the inner structure of the body member less clearly than the transmission image.
