Research Findings:

  • reCAPTCHA v2 is not effective in preventing bots and fraud, despite its intended purpose
  • reCAPTCHA v2 can be defeated by bots 70-100% of the time
  • reCAPTCHA v3, the latest version, is also vulnerable to attacks and has been beaten 97% of the time
  • reCAPTCHA interactions impose a significant cost on users, with an estimated 819 million hours of human time spent on reCAPTCHA over 13 years, which corresponds to at least $6.1 billion USD in wages
  • Google has potentially profited $888 billion from cookies [created by reCAPTCHA sessions] and $8.75–32.3 billion per each sale of their total labeled data set
  • Google should bear the cost of detecting bots, rather than shifting it to users

“The conclusion can be extended that the true purpose of reCAPTCHA v2 is a free image-labeling labor and tracking cookie farm for advertising and data profit masquerading as a security service,” the paper declares.

In a statement provided to The Register after this story was filed, a Google spokesperson said: “reCAPTCHA user data is not used for any other purpose than to improve the reCAPTCHA service, which the terms of service make clear. Further, a majority of our user base have moved to reCAPTCHA v3, which improves fraud detection with invisible scoring. Even if a site were still on the previous generation of the product, reCAPTCHA v2 visual challenge images are all pre-labeled and user input plays no role in image labeling.”

    Maybe a billion dollar company has the budget to come up with something?

    Looking at the numbers in this post, reCAPTCHA exists to make Google money, not to keep bots out.

    I’d rather have no reCAPTCHA than the current state.

      Hi it’s me. I work for a billion dollar company with a budget. We have no ethical ideas on how to stop bots. Thanks for coming to my tech talk.

        Yeah, that’s about the way I’d expect it to go.

        “Traffic resulting from reCAPTCHA consumed 134 petabytes of bandwidth, which translates into about 7.5 million kWhs of energy, corresponding to 7.5 million pounds of CO2. In addition, Google has potentially profited $888 billion from cookies [created by reCAPTCHA sessions] and $8.75–32.3 billion per each sale of their total labeled data set.”

        There might be a tiny chance they’re not interested in changing things.
