hi, can anyone tell me more about the captcha used for the keyword suggestion tool? Is it a captcha I can download and use for free? I'm looking for a open source one in perl or php. Or if someone can suggest a different captcha along with a working example, I'd very much appreciate it. thanks Sane
You can find a useful captcha ready to use script with audio verification here http://bokehman.com/captcha_verification And if you want to code it yourself - this might prove useful: http://frikk.tk/comments-273-03.15.06.htm
Thanks for the links max_pain. I may put off developing my own captcha and file it with my other projects like developing a theme spider. Shawn, any chance that you might share your captcha with the dp community? Either way, can you tell me what technology you used to develop it? It's a really cool implementation. Thanks Sane
It's not really any technology... just PHP code. As far as sharing the code, I'm not to keen on sharing stuff that is used for security... you might get people trying to reverse engineer it to figure out how to defeat it, which would be a pain...
