In 2007, Google introduced a unique user authentication system for reCAPTCHA (a fully automated public Turing test for computers and people), which is easy to use but also extremely difficult for software robots. In addition, the user must simply click on the box to confirm that there are no robots. Immediately afterwards, the Google system checks how the mouse moves, the device's IP address, and some other key information. Based on this, it determines whether the user is "OK" or requires additional authentication (for example, by clicking on the squares of the displayed image).
Although users with Google's ReCAPTCHA system are relatively satisfied, they have decided to modernize it with the technology genius. The third generation of the reCAPTCHA system will basically be the same as its predecessor, but it will work in the background, meaning it will be invisible to the user. This means that the user will automatically recognize the user, and that will do the intended algorithms. The third version of the reCAPTCHA system will basically rely on a risk analysis to determine if there is a suspicious transmission of generated robot data in the background, which is undesirable especially among advertisers.
The new version of the reCAPTCHA system works in the background of the web site and continuously evaluates the behavior of users with a rating of 0.1 (bad) to 1 (good). The site manager decides when to "activate" it and has three options to use the novelty. The first is to define the limit itself, where an additional check is required, such as a two-step verification. Another possibility is a relationship with reCAPTCHA estimation with data that Google can not access, such as a user profile and history of completed purchases. The third option is to directly use the reCAPTCHA system to learn its own anti-fraud system, using its own solutions and side solutions.
The only problem with the new system of reCAPTCHA v3 is, however, that, in the opinion of many experts, the problem is overcoming the privacy of users. This gives the end user more accurate tracking, which of course could be used by online advertisers. Despite numerous allegations of privacy denial to World Wide Web users, Google does not want to find out how the new reCAPTCHA system works. This would make the villains on the Internet greatly simplified their lives.
