I'm sure most of you have at some point been exposed to a CAPTCHA control on the net. They come in loads of forms and are used to tell the difference between humans and computers (bots). If you have a website on the net, you are prone to lots of different kinds of attacks from bots - such as CSRF (Cross-Site Request Forgery) You may have noticed that on some sites you get asked simple math questions or other simple questions when submitting or posting information. One of the more common controls out there is a captcha like control.
