Exploring the Potential of NIR Reflective and NIR Absorptive Materials in the Manufacture of Attack Tools for Biometric Systems

The classic spoofing attack on vascular pattern biometric systems most often uses attack tools based on a printed copy of the user's veins. This paper presents the results of an investigation into the possibility of using NIR absorbing/reflecting materials to produce attack tools against this type of biometric system. The authors have developed the concept of a new artefact that is produced directly on the attacker's hand without using a printed copy of the vein pattern. The attack artefact is created in two stages: in the first stage, the attacker's vein pattern is obscured with NIR-reflecting substances, and in the second stage, a control pattern is applied with a NIR-absorbing substance.
