There are different forms of CAPTCHA. Sure it isn't foolproof but if you just pick another kind of image garble you have a chance they won't break it :P
The more different types of CAPTCHA we use / make the less chance you have of others breaking it :) You could try for instance to break up the images.. 2 or 3 images making up the entire CAPTCHA will probably work :) Good luck though :) ----- Original Message ----- From: "Falls, Travis D (HTSC, CASD)" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Wednesday, July 27, 2005 5:25 PM Subject: RE: [AspNetAnyQuestionIsOk] Image Verification > Thanks Pete, I didn't know that and had planned on relying on them. > Anyone > have another idea on how I can validate that a human is submitting a form > and not a crawler of sorts? > > Travis D.
