Tickemaster has launched a new online ticketing system that includes a step that helps prevent unfair use of

automated programs. In an effort to deter the efforts of computer hackers (and presumably scalpers), the new system prompts users to enter a random word, which is visible to the human eye, but not detectable to the automated programs. This extra step also helps reduce system loads, which improves website performance.
The program that makes this possible is called CAPTCHA. To learn more, visit www.captcha.net.
