CAPTCHAs ( Completely Automated Public Turing-tests to tell Computers and Humans Apart ) How can websites tell humans and robots apart? 'SIGN up for a new e-mail account, buy a concert ticket or leave a comment on a website and you will often be confronted with an image of skewed and swirled letters and numbers to be transcribed before you are allowed to proceed. “Completely Automated Public Turing-tests to tell Computers and Humans Apart”, or CAPTCHAs, are used by websites to determine whether the user is a real person or a robot. Recently boffins at Vicarious, a tech firm, posted a video of its artificial-intelligence software outwitting popular sites' CAPTCHAs, but so far the company has provided no rigorous proof of its system's capabilities. Commercial and academic researchers frequently release papers describing how they broke one CAPTCHA type or other, but programmers react by making the distortions even more fiendish and unreadable.' They can be a pain! How does a CAPTCHA decide who is a human and who is a robot? Some are pretty 'easy' some like the above is more like a Bletchley Park code! And they wind us up for sure.

A better version would be to say what you see, unfortunately many people can't read Stereograms.
