🔍 Exciting developments in #BiometricTech! The patent grant #US18654682B1, assigned to #Apple $AAPL, introduces a method for #EyeAuthentication using adaptive decision thresholds and normalizing distances. This innovation involves capturing an eye image, transforming it into an iris feature representation, and applying a similarity scoring technique. The score is compared to a threshold to authenticate users on devices like head-mounted displays. #VisionPro
