A test used to make sure that a human, not a computer program, is using a system.
The test typically involves reading distorted text.
 ETYMOLOGY: 
An acronym of Completely Automated Public Turing Test to tell Computers
and Humans Apart. The Turing test is named after Alan Turing, a mathematician
and computer scientist, who proposed that a computer could be considered

not tell which is which. A captcha is a kind of reverse Turing test. Earliest 
documented use: 2001.
 USAGE: 
“Yet here we are, watching a carrier [Ryanair] that considered charging
passengers to pee, opening a Twitter account, accepting American Express
credit cards, and removing its annoying Captcha.” Pol O Conghaile; Be Travel Savvy; Irish Independent (Dublin); Oct 5, 2013. A THOUGHT FOR TODAY:In religion, faith is a virtue. In science, faith is a vice. -Jerry Coyne, biology professor (b. 1949) |
