Recapcha v3 “Identify whether it is a bot without authentication… ”

On the website authentication screen, you may have seen a case where you check the phrase that you are not a robot or select an image such as a traffic light or a pedestrian crossing and press it. It is using reCAPTCHA. Recapcha is a system that automatically identifies robots and humans. With the latest version, Recapcha v3, human users can prove that they are human without doing anything.

Recapcha v3, a new version of the robot identification system provided by Google, is a cumbersome task in which the user sees and enters captcha, unlike the existing Recapcha, in order for the risk analysis engine to evaluate user behavior on the site and identify whether or not a bot is a bot. There is no need to do anything. This system is convenient and simple. However, some experts point out that the user’s personal information is being sacrificed behind convenience. The reason is that Recapcha v3 uses cookies to rate users.

Experts have tested the behavior of Recapcha v3 and found that Recapcha tends to rate robotic risks as low at all times when accessed from a browser logged into a Google account. On the other hand, accessing from a browser using Tor and a VPN is considered a high bot risk.

What’s even more annoying is that Recapcha v3 is introduced not only on the login screen, but on all web pages of the basic Zergall site. This, of course, has a reasonable reason to increase the accuracy of bot classification risk assessment by observing user behavior in detail within the site. However, in other words, when accessing a site that introduced Recapcha, all actions of users are leaked to Google.

In addition, since the recapcha included in the webpage supports social media functions in the same way as the Facebook Like button, there is a possibility that the influence of the recapcha will reach social media beyond a specific site. Google pays attention to this point, and announced that the data acquired through recapcha will not be used for advertising targeting and user interest or interest analysis.

It can be said that not only recapcha, but also convenience on the Internet is always like a double-edged knife. Instead of enjoying the Internet safely and stress-free, you cannot avoid exchanging personal information. Related information can be found here .
