[NFBCS] Automatic Captcha solving

[Peter]

Good afternoon again everyone,

	Or the resource employs an authenticator that requires no action from the user. They can verify that you're a human without the need for any interaction. I believe that ReCaptcha works this way. I know of one Website that uses such a system without requiring any interaction from site users. Perhaps we should advocate for the use of such systems to become the gold standard on all resources requiring authentication to insure that the resource is protected from unauthorized users and spammers and insures that those who use assistive technology can do so independently.

You act like what I am saying is theoretical.  saying that it won’t happen is just simply not true. ..

Do a search yourself by googling, “github solve captcha OCR” and you will find many, many different things such as what our first provided in the original email. 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.
