The Evolution of the Captcha
The Evolution of the Captcha
Introduction

We have done it thousands of times. Squinted at blurred letters. Clicked every square with a fire hydrant. Ticked the checkbox that says “I’m not a robot”. Proved that we are human to gain access to a website. It feels like a silly, sometimes annoying game, just to prove we deserve entry to a site. This is the story of the CAPTCHA

Here’s something to think about. We helped scan millions of old books. We trained cameras on self-driving cars. We did it for free, without being asked and without even knowing. And now the CATCHA has gone invisible. We were tested, we were used, and now we are being watched. The question now is: if we had known about this from beforehand, would we have clicked ‘agree’? Let us know what you think in the comments box.
A last nugget of information: Look at the full name again — Completely Automated Public Turing test to tell Computers and Humans Apart. The CAPTCHA has always been a Turing test. What’s a Turing test? That’s a story that deserves its own feature — and it’s coming up soon in TPPJ.
