From the developer:
Lanapsoft BotDetect™ prevents automated submissions of ASP.NET forms using CAPTCHA images. The ASP.NET Custom Web Control generates and validates best-of-class Captcha images specifically designed to be out of reach of current computer vision and OCR technologies. The control provides a sound Captcha alternative as well, to keep ASP.NET web applications accessible to the blind and other people for whom reading the Captcha code could be a problem
