Forget security – Google's reCAPTCHA v2 is exploiting users for profit | Web puzzles don't protect against bots, but humans have spent 819 million unpaid hours solving them (www.theregister.com)

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."

I don't really get where this article is going. They are all over the place.

Let's start with a fuck google. They are a evil company. But:

  • Other captchas are also not very effective against bots. Arguably most traditional systems would be worst that recaptcha at fighting bots.

  • Recaptcha agent validation while a privacy violation is faster than solving any other captcha and if you are hit with the puzzle is not that much more time consuming that every other captcha.

  • That profit number is very questionable and they know it. Anyway, that's no much different and probably less profitable that most google services.

Also is ridiculous how someone can say in the same article that the image puzzle can be solved by bots 100% of the time and that is a scheme to get human labor to solve the puzzle. Am I the only one seeing the logical failure here?

And what's the purpose of all this? Just let bots roam free? Are they trying to sell other solution? What's the point?

I hate google as much as the next guy. But I don't really share this article spirit.

If I were to make a point. They point will be that people and companies should stop making registration only sites and dynamic sites when static websites are enough for their purposes. And only go for registration or other bot-vulnerable kind of sites of there is no way around it. But if you need to make a service that is vulnerable to bots, you need to protect it, and sadly there's not great solutions out there. If your site is small and not targeted by anyone malicious specifically you can get with simpler solutions. But bigger or targeted sites really can't get around needing google or cloudfare and assume that it will only mitigate the damage.

But if anyone knows a better and more ethical solution to prevent bot spam for a service that really need to have registrations, please tell me.

Also worth noting that Google has always been extremely open about the fact that they use recaptcha for that purpose. It's never been a secret.

Their service to the website owners is the meaningful reduction in effectiveness of bots in places bots are harmful. The website's service to you is the content that that's being used to protect (and the stuff that has recaptcha on it is stuff like games where there's a competitive advantage, things like search engines where there's a meaningful cost to heavy bot use, and login pages where there's a real security cost to mass bot use). I use a VPN, which increases the rate of captchas a lot, and I think it's a pretty reasonable way to do things, personally.

Most solvers aren't bots. Logical, right?
