What is CAPTCHA?
CAPTCHA is a system developed to prevent automated submission of online forms by requiring human input, it is primarily used as an anti-spam tool as many spammers crawl the web (using automated systems) submitting their links and web addresses to as many web forms as possible.
How does your CAPTCHA system work?
Our CAPTCHA system is currently a very basic system - but it works. The user simply has to correctly identify the main colour of the CAPTCHA image in order to prove that they are in fact human and not an automated program. We will develop our system in the future but at present it does what it needs to do and protects our clients from, in some cases, hundreds of spam submissions per day.
