Can anyone say if this camera method includes detection if the finger is alive or a static image? Early fingerprint detectors could be spoofed by static images

Early fingerprint detectors could be spoofed by static images (on paper, plastic or other materials) while modern detectors use various methods for liveness detection. It should be obvious that few commercial implementations would like to use something that can be fooled by a static image.
- yorwba 9y agoIt's possible to detect the minute changes in skin color caused by the pulse, so you could distinguish a live finger from a fake (unless it has a pulsing light...) This paper doesn't mention anything about verifying liveness, though.
