CAPTCHA -  Completely Automated Public Turing Test to Tell Computers and Humans Apart.

 One of the first search engines - Alta Vista, in 1997, needed a way to determine the difference from humans and machines / computers which were used as "Bots" which skewed the ranking of websites.  

This promoted the Chief scientist of Alta Vista,  Andrei Broder to develop an algorithm which created a print image that computers could not recognize.  

Turing, named after -Alan Turing, a computer scientist, cryptanalyst, mathematician and theoretical biologist, further enhanced the AI to allow for the algorithm to determine the difference between machines and humans.
