First off, what’s a Captcha?
A Captcha is a type of test designed to tell man (aka user) from machine (i.e. computer). You no doubt had the opportunity to see such an image composed of scrambled letters on an Internet subscription form. They’re usually painstakingly hard to decipher.
Recently, a new Captcha system, cleverly named NuCaptcha, has made its appearance. The concept remains the same, but a Flash video with scrolling text replaces the incomprehensible words in a picture. Needless to say the benefits are numerous, security- and visual-wise.
