Spoofing is a real concern with regard to the security of biometric systems, especially in personal identification systems based on contactless hand biometrics which can be easily fooled with a simple hand picture. This study proposes a new approach to increase the security of contactless biometric devices using a skin detector based on reflectance spectroscopy in visual, near infrared and short wave infrared bands. The proposal is evaluated with a set of genuine and synthetic hands made from different potentially spoofing materials.
