Google Online Security Blog: Are you a robot? Introducing "No CAPTCHA reCAPTCHA"

You can tell how the new reCAPTCHA proposed by Google can be used by watching the following movie.

Introducing the no CAPTCHA reCAPTCHA - YouTube


The reCAPTCHA function is effective as a means to block bots attacking the website.


However, the bot continues to evolve year by year, and character recognition of reCAPTCHA which was impossible in the past is being broken through.


While strengthening reCAPTCHA that could be broken by Bot, Google thought that there was no way to prove "being a human rather than a bot" more easily.


And it is the new reCAPTCHA that I could do.


The new reCAPTCHA is a bot selection function embedded in the website like the conventional reCAPTCHA, but no character input is necessary. It is possible to operate by clicking and tapping.


If you use the new reCAPTCHA, anyone can easily prove that it is not a bot.


The concrete usage is like this. When I check "I'm not a robot (I am not a bot)", I will display the image "Select all images below that match this one: (Please select the same thing from this below from the bottom)" As an example comes out, just select the same image as the image example from the bottom and click / tap. Since character input work like conventional reCAPTCHA is unnecessary, it can prove that it is not a bot easily even for a mobile terminal which is difficult to input characters.
