True. The class I mentioned was written specifically for an online game that uses this type of "human-detection". What it does is filter out most of the quirkies put into the image to make them hard to decypher, do a remapping to a smaller b/w image and then perform a simple OCR. For the site it was built for, it's about 90% accurate. In the other 10%, the site won't accept the registration (in which case the script simply tries again). I think using this technique (and doing it properly) will scare away most script kiddies though. _______________________________________________ jdev mailing list [EMAIL PROTECTED] http://mailman.jabber.org/listinfo/jdev
