If you’ve signed in to almost any website on the Internet, you’ve probably encountered a dastardly CAPTCHA. A CAPTCHA is a common security tool that asks you to type the words or letters you see in a box to prove you’re a human; those words or letters are usually swirled or mangled, difficult for a computer or bot to make out but hypothetically easy for a human to read.
A typical CAPTCHA.
I say “hypothetically easy” because these mangled-text CAPTCHAs can often be frustrating, even impossible, to decipher. (There’s a Tumblr dedicated solely to so-called “CAPTCHA Fails”.) So thank goodness a new company, Are You A Human, has come up with what seems a much more elegant solution: Instead of attempting to decipher some indecipherable text, you are asked to defeat a simple arcade game to prove that you are real.
