CAPTCHA – what??

privacy-card-3x2We have seen it a million times, but what does CAPTCHA actually stand for?

It is an acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart” and is basically a test to see whether the user is a human or an automated software application known as a bot.  bots are “bad” when they are programmed to break into user accounts, scan the web for contact information for sending spam, or perform other malicious activities.


You’ll come across a CAPTCHA request when registering new accounts and or submitting information on online. CAPTCHA is based on the premise that humans can more easily recognise highly distorted, rotated or skewed characters, can more easily visually separate overlapped characters and are able to draw on context to understand visually distorted characters, for example, identifying a character based on the full word that it appears in.
