Google invented a new kind of captcha (captcha)

A new kind of captcha forces users to rotate images to a standing position in order to prove their humanity.

The user needs to orient several images correctly ( upd: it is obvious that the correct positions of the images will not be displayed; see the real application examples below)

Warning: a lot of images under the cut.


Simplified working principle

The essence of innovation is that it will be harder for bots to orient the images than to recognize the text. True, you need to take into account the fact that there are images that cannot be correctly oriented and such images should not be included in the Turing test.
You can also show images that are thematically relevant to the site, and not recognize the text, often absurd, ridiculous, and sometimes offensive.

This is how it looks on a mobile device.


And so in the browser

- CAPTCHA [ˈkæptʃə] (from the English. "Completely Automated Publication Test") is a fully automated public Turing test for distinguishing between computers and people.
