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.”
Gonna have to disagree hard with this, based on extensive first-hand experience (web dev). I’ve added CAPTCHA to dozens (hundreds?) of web forms, and it all but eliminates spam.
Right, so similar to locks? Usually can be easily bypassed if you know how, but it at least filters out the people who aren’t determined enough to put in the effort.
Basically, yeah. The vast majority of spambots are simple and lazy.
My experience matches yours. I don’t enjoy putting recapcha v3 on my sites but it takes contact form spam from 70-80 messages per day to 0-2.
I’d switch to other services if they could be as effective. If anybody has real-world experience with another option working I’d love to hear it.
Honestly at first read, the paper feels like a bunch of whining text to prove a point the author believes in without any alternate proposal.
It works against basic bots, but if you’ve got a dedicated adversary, it doesn’t do anything
(Granted, most people do not have dedicated adversaries, but when they come, you’re in trouble)
OK, sure, but that’s like saying it’s pointless to use a secure password online because the NSA could hack you if they wanted to.
