Captcha form verification

Online webforms are being targeted by spam emailers to send more spam.

If you have a form online you need to make sure spam robots cannot use it. Captcha is used to protect web forms against spammers. The code stops automated computer spam robots from filling out forms, harvesting email addresses, and then sending out countless spam emails. If your form is used by spambots this could lead to your domain being banned.

Beyonder will implement Captcha on your web form to ensure it is fully secure and safe to use.

How the Spam is Blocked - People and automated computer spam robots never see your email address because it is hidden deep within the "back end" code on your website. It is not on the visible webpage being viewed and it is not in the source code.

From Wikipedia, the free encyclopedia
(Redirected from Captcha)

A CAPTCHA (an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart", trademarked by Carnegie Mellon University) is a type of challenge-response test used in computing to determine whether or not the user is human. A CAPTCHA involves one computer (a server) which asks a user to complete a test. While the computer is able to generate and grade the test, it is not able to solve the test on its own. Because computers are unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. The term CAPTCHA was coined in 2000 by Luis von Ahn, Manuel Blum, Nicholas J. Hopper (all of Carnegie Mellon University), and John Langford (of IBM). A common type of CAPTCHA requires that the user type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appears on the screen.

Because the test is administered by a computer, in contrast to the standard Turing test that is administered by a human, a CAPTCHA is sometimes described as a reverse Turing test (although this term is ambiguous because it could also mean a Turing test in which the participants are both attempting to prove they are the computer).
