In the present chapter, multibiometric techniques are included in this category. Multibiometric anti-spoofing is based on the hypothesis that the combination of different biometrics will increase the robustness to direct attacks, as, in theory, generating several fake traits is presumed to be more difficult than an individual trait. Such a strategy requires additional hardware acquisition devices, therefore these techniques may be included in the sensor-level group of presentation attack detection methods.
