Google Invisible reCAPTCHA

In plain words

Google Invisible reCAPTCHA is a tool that protects websites from spam and automated abuse without requiring users to solve puzzles or prove they're human through traditional verification methods. The service works invisibly in the background, analyzing user behavior to determine legitimacy. It's designed for website developers and administrators who need security solutions that don't compromise user experience. The tool integrates with Google's existing infrastructure and threat detection systems.
