Q. Moni Naor was the first person to theorize a list of ways to verify that a request comes from a human and not a bot. Primitive Xs seem to have been developed in 1997 by Andrei Broder, Martin Abadi, Krishna Bharat, and Mark Lillibridge to prevent bots from adding URLs to their search engine.In order to make the images resistant to OCR (Optical Character Recognition), the team simulated situations that scanner manuals claimed resulted in bad OCR. In 2000, Luis von Ahn and Manuel Blum coined the term 'X', improved and publicized the notion, which included any program that can distinguish humans from computers. They invented multiple examples of Xs, including the first Xs to be widely used, which were those adopted by Yahoo!.
