SPOOFINGDETECTION 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.
