Biometric Update | Biometrics News, Companies and Explainers by Chris Burt
“In essence, some of today’s research is focused on thermal infrared (a technology that cannot easily be used with today’s CCD chips) to depict the blood vessels and structure of veins in the human face. This thermal infrared imaging brings unique physical properties that can help identify cyberattacks like presentation attacks, spoofing and more.”
Because current mobile phones already include NIR sensors, Lindemann argues the industry should focus on leveraging that technology to achieve mass adoption.
The diameter of the average blood vessel is only 10 to 15 micrometers, he points out. Finger and palm vein biometrics can be captured without high resolution cameras, whereas people expect image capturing to take place at a larger distance for face-based systems. Recent advances in CCD camera resolutions has made facial vein biometrics a practical option, however, according to Lindemann…
