[NFBCS] Automatic Captcha solving

Tue Mar 30 02:54:54 UTC 2021

Captcha is a security measure. You are completely right but a solution such as what I am alluding to wouldn’t be permanent. However, Security is a cat and mouse game. Google or whomever implementing captcha and spammers or those wanting to be lazy like myself find ways to avoid the measures. 

Google implement captcha, OCR solves it. Captcha implement sound as well as characters, voice recognition like the link I provided can bypass it. It is a never ending game where one side reacts to the other.

I am not wanting one of these add-ons, scripts, services, etc. for spamming. I am just wanting to be able to have captcha automatically solved for speed, a little bit of laziness and also because not all captchas are accessible. I plan to try out something similar to the link I provided in the original email if nobody on the list has any other recommendations or has used something similar.

That has historically been a hard problem, so it hasn't really been a major issue. You are correct in pointing out that this is not necessarily the case now though, which probably means they'll be changing the technology again. We're already seeing signs of that happening. The changes could be something as simple as doing something to the text to make it harder to recognize, or it could be something as major as redesigning how the system works in its entirety.

Delays between key presses, browsing history, etc. Not sure of *all* of the factors. That system will present a captcha if it isn't pretty sure the entity is human though, so accessibility of the captcha is still important.

I wasn’t asking what a captcha is for the purpose, I was asking if anyone has used an automated extension, script or app that solves them such as the one initially provided.

If OCR or any other automated technology could be used to solve the captcha, there would be no point in using one. If a blind person could use OCR to solve it, so could any other automated system incorporating OCR technology. The same thing goes for any other automated solution one might come up with for the solution of captchas. In fact, captchas are specifically designed to be hard to solve by automated means. For example, the ones that require you to enter a code you see on the screen have the code blurred, in funny fonts, or otherwise obscured in a way that makes it hard for automated systems to recognize the characters. Most captchas today do have an audio option that you can use as an alternative to the visual captcha. You might argue that this is harder than just using an automated solution, and you're right, it is. That's the point though; the captcha is designed to explicitly require human interaction in order to proceed.
