CAPTCHA and reCAPTCHA are systems that are used in order to verify whether or not the user of a device is human or robot. And according to surveys, netizens find reCAPTCHA very irritating but they cannot avoid it because it is really necessary. This verification has been around for quite a while and it had to evolve since gadgets, machines and operating systems were getting better.
With its latest iteration, as reported by Life Hacker, Google will no longer have to input anything at all. Meaning, there will be no reCAPTCHA and it will be replaced by the invisible CAPTCHA soon. The latest development for the challenge-response systems in the "Completely Automated Public Turing test to tell Computers and Humans Apart" is said to be the invisible CAPTCHA.
As a history, Google acquired reCaptcha back in 2009, it updated the system in 2013 in order to allow for the ubiquitous "I'm not a robot" dialogue with a checkbox that's all over the internet. That version operated by defining the user's humanity. as well as understanding, through their clicking style. If the click appeared to be something fishy, a more detailed test would pop-out and will be offered to the user. The new invisible CAPTCHA is also able to recognize if a user is not a bot by simply analyzing the browsing behavior.
In a video released by Google, the company explained that empowering the advances in technology is a combination of machine learning and excellent risk analysis which adapt to new and emerging threats. Shuman Ghosemajumder, a Google employee said to Popular Science, "Google, in general, believed that anything that is good for the internet, is good for Google." He also pointed out that Google records all the past behavior of each user especially when they're logged in, which would give the system more accurate view.
