Notes:
A common CAPTCHA presents distorted alphabetic letters and asks the user to type them into the computer. Since today’s computers are not as good at that kind of recognition as humans, accurate entering of the letters indicates a human user.

CAPTCHA is an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart."  Click on the Wikipedia article for more information.
