Captcha 'I'm not a robot' showed what it came for (and it's not to stop robots)

If you're not a robot and you've come across this question on the internet, know that it's totally common! Of course, you already had to prove it to the captcha that you really aren't a machine, separating real users from bots.

The name of Captcha, translated, is “Completely Automated Audience Test to Tell Computers and Humans Apart”.

Tests seem to be totally predictable – and they really are easy. Clicking on images that contain a motorcycle, traffic light, mountains or many other things that can fit. It could be a simple “click here and show me you are not a robot”, but the test needed to be a little more complicated.

Captcha, the human test

A video that went viral, made on the British television program IQ, revealed that the test can observe our behavior before pressing the button. Robots were created to click the button, but there is no way for them to behave like a human, so they cannot pretend to be normal.

Cloudflare, a cybersecurity firm, said the test tracks user movement as they move their mouse to the answer box. For the analysis, the simplest human movement can be different and these are characteristics that bots cannot imitate.

In addition to capturing the movement until clicking on the box, Captcha will evaluate the cookies that are stored on the user's device, as well as being able to analyze the click history. Whether it's cookies or history, Captcha can detect it.

“Say, for example, before you tick the box, you watched some cat videos, liked a tweet about Greta Thunberg checked your Gmail account before starting work - all this makes them think you must be human", said QI host Sandi Toksvig.

Only when this single search is not enough for the analysis, do you need to use images to prove that you are a human. However, you can rest assured if you really are not a robot!
