Computer Literacy Tests: Are You Human? // Time (magazine). Архивиран от оригинала на 30 април 2009. Посетен на 12 юни 2008. The Carnegie Mellon team came back with the CAPTCHA. (It stands for „completely automated public Turing test to tell computers and humans apart“; no, the acronym doesn't really fit.) The point of the CAPTCHA is that reading those swirly letters is something that computers aren't very good at.
