In 2007, Google introduced a special system to authenticate users of reCAPTCHA (fully automated Turing test to inform computers and humans), which is easy to use, but at the same time extremely difficult for software robots. With it, the user only has to click on the box to confirm that there is no robot. Immediately afterwards, the Google system checks how the mouse moves, the IP address of the device, and other key information. From this fact, it decides if the user is "in agreement" or if additional authentication is needed (for example, by clicking on the squares of the image shown).
Although users with Google's reCAPTCHA system are relatively satisfied, they decided to modernize it with the technology giant. The third generation of the reCAPTCHA system will be essentially the same as that of its predecessor, but it will work in the background, which means it will be invisible to the user. This means that the user will recognize the user automatically and this will be done through dedicated algorithms. In fact, the third version of the reCAPTCHA system will be based on a risk analysis to determine if there is a suspicious transfer of data generated by fund robots, which is not desirable, especially among advertisers.
The new version of the reCAPTCHA system works in the background of the website and continuously evaluates the behavior of the user with a score of 0.1 (bad) to 1 (good). The site manager decides when "active" and has three options to use news. The first is to define a limit in itself, where additional verification is needed, such as a 2-step verification. Another option is a link to the reCAPTCHA estimate with data that Google can not access, such as a user profile and a completed purchase history. The third option is the direct use of the reCAPTCHA system to learn its own antifraud system, using its own solutions and external solutions.
The only problem with the new reCAPTCHA v3 system, however, is that, according to many experts, the problem is to overcome the privacy of the user. This allows even more accurate tracking of the end user, which, of course, could be used for online advertisers. Despite numerous accusations at the expense of denying privacy to users of the World Wide Web, Google does not want to reveal how the new reCAPTCHA system works. In this way, the villains on the Internet would greatly simplify their lives.
