In 2014, Google announced the ‘reCAPTCHA,’ (Completely Automated Public Turing test to tell Computers and Humans Apart). Since then it changed a number of methods to distinguish between human and bots on the web particularly while filling the forms in websites.
Now Google Announced an all new invisible reCATTCHA. This new API also lets us experiment with new types of challenges that are easier for us to use, particularly on mobile devices.
In its official blog Google said “On websites using this new API, a significant number of users will be able to securely and easily verify they’re human without actually having to solve a CAPTCHA. Instead, with just a single click, they’ll confirm they are not a robot.”
Even though the new process is invisible, it will still consider variables like your IP address and the movements of your mouse.
Google says its technology will “actively consider a user’s engagement with the CAPTCHA — before, during, and after — to determine whether that user is a human.”
