Most open source text captchas have ML/DL or OpenCV OCR solutions and more advanced captchas like gcaptcha/hcaptcha you can send to a solver farm like 2captcha. The cost for the farm solutions is pretty cheap.
- WaxProlix 6y agoI'd only seen relatively pricey solver farm solutions, hence the question. What constitutes "cheap" here? For a baseline, .05USD/captcha seems not cheap to me.
- hshshs2 6y agofor a server farm you could purchase as a normal citizen, but what do governments pay?
- adanto6840 6y agoCan be had much cheaper, especially if OK with a non-zero failure rate (and/or bit more latency). Note that my hands-on experience with this stuff is now relatively dated, from a "prior career" -- coming up on 10 years now, even. If anything though, then I'd guess that it's become cheaper over time, not more expensive.
- BeefySwain 6y agoLook again, that is per thousand captchas. Still pretty expensive if you wanted to do every single Valid CC #, though.
- xzel 6y ago2captcha is about 0.0005/solve, give or take do to their failure rate. There are other services as well and pre-paid bulk purchases lead to lower pricing. I wouldn't want to ballot stuff the crazy number that is the combination of all Visa credit cards but for much smaller problem spaces 2captcha and others are very reasonably priced.
- StavrosK 6y agoI would easily pay 0.0005 per solve if it meant I don't have to deal with a captcha again when browsing.
- asadlionpk 6y agoI assume there is a business opportunity here.
- Scoundreller 6y ago"Break something and then sell the solution" is always a business opportunity.
- xur17 6y agoThe biggest issue here is solve latency. If I'm on a page with a captcha, I would definitely pay $0.0005 to not have to solve the captcha (hell, I'd pay $0.01), but I'm not sure I'd pay $0.0005 and wait 30 seconds.
- xzel 6y agoThere is buster: https://github.com/dessant/buster https://github.com/dessant/buster Wasn't something I mentioned earlier but using the reCAPTCHA audio is also another solution for gcap. I haven't ever used it personally but always seemed like a cool idea.
- ornornor 6y agoI use it all the time and it works very well. I got my own tts api token so that I don’t run into overquota errors from the shared default token. It’s also very satisfying to know I’m not an unpaid mechanical Turk for google anymore and that it’s a machine solving another machine’s challenge.
- StavrosK 6y agoI'll try that, thanks! I can confirm audio CAPTCHAs are much easier, I always use those.
