GOOGLE'S reCAPTCHA has introduced a hand gesture verification system in beta to combat advanced bots. This innovative mechanism requires users to record brief hand movements that are sent to Google for analysis, extracting 21 knuckle coordinates without linking to personal identity or retaining the footage post-verification. The system aims to thwart sophisticated AI bots that can easily bypass traditional CAPTCHA methods.
Users must grant camera access to use this feature, adhering to strict privacy policies that prohibit data sharing with third parties. Overall, this gesture-based system provides an additional layer of security against automated scripts.
