Google Teases Invisible reCAPTCHA Requiring Less Interaction to Differentiate Humans From Bots

In 2014, Google announced its 'NoCAPTCHA reCAPTCHA' technique to tell humans apart from computers and mostly got rid of its annoying reCAPTCHA technique. Now, the search giant has teased a new technique that is claimed to require no human interaction to identify users as humans.

Even though Google has not mentioned any particular release timeline for the new identification technique, on its teaser page, it says that it will be 'coming soon'. The new technique has been termed as 'Invisible reCAPTCHA'. CAPTCHA is an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart" and was devised as a technique to differentiate between bots and real humans online, and made users decipher and type out the characters or numerals that appeared on screen.

The CAPTCHA technique and reCAPTCHA techniques have seen several iterations over the years, including making users answer a simple mathematical equation, or selecting appropriate images from a series of images.

The 2014 NoCAPTCHA reCAPTCHA method however made things much easier, featuring an identification test that just made users ticking a checkbox that sits beside the text "I'm not a robot". In order to determine whether the user is a human or a bot, Google runs several tests using its 'risk analysis engine', identifying whether the user was human or robot by analysing mouse movements and other intricacies of human behavioural mechanisms. If there was some ambiguity left, users would be shown older reCAPTCHA style tests.

As Google has not provided any further details about its new technique, we will have to wait and see what the company has in store for us.
