Hi all. I've been doing a captcha script lately and was rather successful with it. However I want to create another script that creates a sound which can be used with the captcha.

I'm looking for inspiration here. I need to employ some sort of human verification for my website, but the most common method these days (asking users to type the letters & numbers they see in an image into a text input box) seems a little rubbish - I find it hard sometimes to work out what the letters & numbers are. There must be a bet...

The question is - is there any way to solve the problem without using sessions? Wha...

For completely non-nefarious purposes - machine learning specifically, I'd like to download a huge dataset of CAPTCHA images. However, CAPTCHA is always implemented using some obfuscated javascript that makes getting at the actual images without a browser a non-trivial task, at least to me, who is a javascript novice. So, can anyone giv...

GMail can used as a SMTP server. I've written the code that does it. But as we all know GMail may occasionally authenticate using captcha (image verification as they call it). The same thing may be the cause to reject SMTP authentication. As I've seen google shows image verification when you try to log-in for the first time from some ma...

CAPTCHAs that ask users to read distorted text are fine for sighted people, but a terrible barrier for those who are blind or have other disabilities. Audio alternatives are occasionally available but still don't help those who are both deaf and blind and can be hard to use with a screenreader (which is already reading words to you). Th...
