Who invented CAPTCHA?
Luis von Ahn
Manuel Blum, a computer science professor at Carnegie Mellon, led a group (including Luis von Ahn, Nicholas Hopper, and John Langford) that came up with the first CAPTCHA—an acronym for “completely automated public Turing test to tell computers and humans apart.”
What is the CAPTCHA code?
CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a type of security measure known as challenge-response authentication.
