[Get] intelligent Library for solving security questions/Text Captchas

when trying to automate things like registration and posting ,
the most annoying part isn't the image captcha which can be solved through cheap services but the logic questions, softwares users don't notice this but Text Captchas decrease success rate by about 20%.
on year ago , while developping a software for automating drupal platform, i have created a library for solving text captchas (like the ones from http://textcaptcha.com/ which are widely used on drupal websites)
softwares like xrumer and scrapebox uses a questions database but the questions variations are endless and locating the question in a huge database will consume many seconds which will slow down the posting.

the library can solve most common questions (Math questions,Dictionnary questions,TextCaptcha questions etc...)
i'm releasing the library for free , you can use it in your applications (without restrictions ).


you can test the tool here (require .Net 3.5+)

the library is the same as the one a year ago?

no, there are some improvements

Thanks, man!

I mailed some of the captcher services and asked them if text-capchta solving will be implemented, still waiting for that. Cannot understand why nobody is offering that.

it's hard to provide a reliable text captcha service because the questions can vary heavily.
Examples of text captchas that can't be solved easily:

what is the {url|title|owner} of the website? (need to send the url too)
what is the background of the page?
what is your typed username !

in order to solve these questions :
the captcha service must possess huge database containing questions/answers from all websites (++updates), which costs lot of money and effort.
a simpler solution would be a cloud database where a user solve a new captcha question and send the questions/answer to a shared database so others can benefit, this method is implemented in most softwares, However , Most Text captchas follow a certain pattern and they can be solved by using a proper algorithm, so it's more efficient to include an algorithm for solving known text captchas +cloud database for particular ones.

Yep,Same concept as a rainbow table...Honestly i dont think this would be as hard as you think.
