The current version of reCAPTCHA is both repetitive and tiresome, but Google is aiming to change that with the latest update to its anti-bot system. Instead of asking users to click on images and solve interactive challenges, reCAPTCHA v3 will rely on a score based on user interactions to determine whether someone is human or not.



So a “good interaction” would be given a 1.0 score, whereas an interaction that is likely a bot would be given a 0.0 score. One example of how interactions can be scored is by detecting mouse movement to determine if you’re a human. There will be other methods for identifying human activity.
