> It wouldn't need to be a real iris. Extant aliveness checks typically look for: reflections, pupil dynamics (contractions etc), frequency/resolution - these are all designed to look for digital forgeries (image on screen or paper); this leaves them open to a prosthetic model of an eye mimicking those effects (think a very sophisticated mannequin or doll's eye) backed by a generated retinal image. I was asking if you are aware of such a thing existing.
