SPOOFING DETECTION OF IRIS,FACE, AND FINGERPRINT
Three relevant modalities in which spoofing detection has
been investigated are iris, face, and fingerprint. Benchmarks across
these modalities usually share the common characteristic of being image-
or video-based. In the context of irises, attacks are normally
performed using printed iris images or, more interestingly, cosmetic
contact lenses. With faces, impostors can present to the acquisition
sensor a photography, a digital video, or even a 3D mask of a valid
user. For fingerprints, the most common spoofing method consists of
using artificial replicas created in a cooperative way, where a mold of
the fingerprint is acquired with the cooperation of a valid user and is
used to replicate the user’s fingerprint with different materials,
including gelatin, latex, play-doh or silicone.
