Large study of Recaptcha concludes that it offers hardly any security and that Google deserves billions with it thanks to the tracking

Anyone who has used the Internet reasonably regularly in the past 20 years has been with great certainty about so -calledCaptchashave stumbled.

The abbreviation stands for »Completeely automated public turing test to Tell Computers and Humans Apart« and is primarily intended to keep bots away from websites.

A study that Dr. Andrew Searles from the University of California and currently atRedditIt is discussed again, but suggests that the tool hardly fulfills this task.

Instead, according to the study, it mainly costs time and is also used by Google for tracking purposes.

I'm not a robot

The study is about:ThePaperBesides the title "Dazed & Confused: A Large-Scale Real-World User Study of Recaptchav2" and describes how the data of over 3600 unique users have been collected and evaluated over a period of 13 months.

It is about the Captcha type Recaptchav2. This type uses the check box "I am not a robot" and image marking tasks in the style of "Just click on the pictures with buses" or the like.

The most important knowledge of the study:

  • RecaptChav2 offers hardly any security against bots
  • By 2023, around 819 million hours were applied for loosening captchas
  • Users become faster the more they solve captchas
  • The level of education has an impact on the speed
  • By tracking, Google has earned the equivalent of around $ 888 billion with RecaptChav2 by 2023

Overall, the researchers come to the conclusion that Captchas and RecaptChav2 cause enormous costs (in the form of time) and have little use. Therefore, "RecaptChav2 and similar recaptcha technologies [...] should no longer be used".

Under theReddit-Post, who recently pointed out the study, is diligently discussed.

Almost two years after the paper was published, Captchas are the standard solution, so to speak. At the same time, the study itself does not call a functioning alternative.

Several users who, according to their own statements, indicate websites themselves indicate that captchas have a value.

Among other things, they are compared with simple bicycle locks that people with high criminal energy cannot stop, but at least prevent everyone from simply taking the bike.
