Live Finger Detection
BioStation L2 features the Live Finger Detection 2.0 from
Suprema. The previous live detection technology
analyzes the dynamically changing pattern, liveness
feature and unnaturalness feature of live and new fingers.
Along with improvements to the existing algorithm, the
new detection technology implements liveness decision
engine using dual light source imaging. Using infra-red
and white light, the engine blocks fake fingerprints made
from numerous different materials.
