ReCAPTCHA Goes Stealth While Google Decides If You're A Human Or A Bot

Some of the time they haven't been a bother; other times you've hated them. They're those little boxes that pop up on websites that demand you type in a distorted alphanumeric string or solve a simple puzzle before they let you access the site. They're called CAPTCHAs (Completely Automated Public Turing test to tell Computers and Humans Apart) and Google's latest version has gone stealth. It may be there, but the only time you'll see it is if Google thinks you're a bot. Google has worked to make reCAPTCHA, their world-leading CAPTCHA utility, as easy for the website user as possible.
