Google AI has become so intelligent that it can now recognize whether you are a human or a robot without CAPTCHAs, i.e. without annoying controls, like the tick in a can, or find similar…
We have all come across CAPTCHAs, (the name comes from Completely Automated Public Turing test to tell Computers and Humans Apart). Καθώς τα bots και οι spammers συνεχίζουν να εξελίσσονται, τα CAPTCHAs εμφανίστηκαν σαν μια τεχνική αποφυγής τους. Όμως πάντα ήταν ενοχλητικά, καθώς πολλές φορές ήταν αδύνατο να επιλυθούν ακόμα και από τους people. 
Then, in 2014, Google announced “reCAPTCHA” which did not display puzzles but a simple box that you had to check. Google analyzes your behaviors in by clicking here to determine if you are human. If it noticed something suspicious (like not finding the check box the first time) it would ask you to solve a simple puzzle.
"Invisible reCAPTCHA" or 'Invisible reCAPTCHA' can be added hidden to an existing button on the site, and work flawlessly, understanding if you are a real person. (can also be added via a calls in the Javascript API).
So it's time to bid farewell to CAPTCHAs.
