Google Tests Hand Gesture Verification CAPTCHA That Uses Webcam Biometrics, Already Bypassed With Stock Photos

Google is exploring a new verification method for reCAPTCHA called hand gesture verification (HGV), according to Google Cloud documentation. The system uses access to the user's webcam to record a video of their hand. It prompts users to wave or perform other gestures at the camera so that Google can analyze the video and extract biometric data points to verify that the user is not a bot.
