Google Tests reCAPTCHA System Using Camera and Hand-Tracking Biometrics
By

Summary
Google is testing a new reCAPTCHA system that requires users to turn on their camera and wave at it for liveness detection. The system records a short video of the user's hand, extracting 21 hand-landmark coordinates (finger joints, palm geometry, and movement patterns) to determine if the user is human or a bot. This raises privacy concerns as it involves camera access and biometric data collection from a company known for monetizing user data.
