Recaptcha_anchor@2xGoogle will soon be implementing a new bot-filtering system to replace CAPTCHA. It’s called “No CAPTCHA reCAPTCHA.” This new system is designed to monitor the user’s behavior on the page before clicking the reCAPTCHA button. If the behavior appears consistent with a bot, then it won’t pass the system. If the behavior is consistent with a human, then you get through, no problem!

However, if the algorithm fails on you, you might be stuck proving your humanity the classic way. On the other side of the coin, even if a robot manages to fool this new algorithm, it still has to defeat the classic CAPTCHA! So all in all, it’s double the security with half the hassle!
