Bad news bots, Google’s CAPTCHA can now tell if you’re human on the sly

Posted: 21 March 2017 | By Darcie Thompson-Fields

Google’s CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is now invisible, meaning you will no longer have to check boxes or solve puzzles.

As bots and spammers became more sophisticated, CAPTCHA’s were getting harder for humans to solve. In 2014, Google announced the ‘reCAPTCHA’ which did away with puzzles in favour of a simple checkbox. Google would analyse aspects of your behaviour on the site to determine whether or not you were a human. A robot, for instance, might always click dead centre of the box, unlike a human.

If you’ve been asked to complete a puzzle since 2014 it’s likely that Google has flagged you as suspicious.

Now Google’s artificial intelligence has reached new levels of sophistication and doesn’t even need the checkbox. The advancement is fuelled by what Google is calling an “advanced risk analysis engine.” The Invisible reCAPTCHA is assigned to an existing button on the site and works hidden in the background to discover if you’re a real person.

This advancement means that most people will remain unaware that they are going through a security check as only the most suspicious traffic will be asked to solve a puzzle.

Good riddance to puzzling out which images match with cats.
