Why does a page sometimes believe me when I select that “I am not a robot” and sometimes not?

Internet security requires us to be up to date. Since in 2014 Google announced the launch of reCAPTCHA Users expect, at the end of any web registration, that the program recognizes them as human or rather it warns that a ‘bot‘(a program that performs repetitive, predefined and automated tasks and that allows replicating human action), is on the lookout and if it is better to refresh the page. The latter because there are both optimizing (good) and malicious ‘bots’.

The following note shows the operation of reCAPTCHA as well as its implications on personal data security issues.

Google identifies if the user is human without having to type anything. Instead, it will review the activity prior to admission. The recent history, let’s say. Everything that has been done before clicking on the box “I am not a robot”. Then, reCAPTCHA studies unwritten clues of each user, such as the IP address or active cookies.

Only in this way, by investigating our online behavior, the world search engine will make sure that we are human and not ‘bots’. Also the risk engine is attentive to the movement of the mouse or ‘mouse’ from when it appears in the registry until it is clicked, again, to “I am not a robot”.

This last follow-up occurs because bots usually move around the screen (with the indicator that we see when connecting the ‘mouse’) automatically. Humans, on the other hand, do not usually go directly to the selectable box (the one that verifies whether or not we are a robot), but the route we do is different. In short, it depends on the type of behavior we have, Google will differentiate if it is a robot or perhaps a human.

There are, however, methods that the search giant does not reveal, as the creators of bots would be attentive to the information available. They could, however, design automation to bypass security.

Although data collection by Google with the reCAPTCHA issue is necessary the debate on whether greater protection is necessary to have much more personal data emerges as an important issue in the technological aspect.

In theory, the sole purpose of the advanced risk engine is to identify human users. Although, if we delve into it, technology portals warn that what is being done is “to know what human we are through the web of cookies of the search engine’s company”, as read in an article by GenBeta. That allows them, while verifying humanity, to build more complete profiles of our online behavior.
