This is a really cool idea. As far as spammers obfuscating their images, couldn't that be worked around by tying OCR into the bayesian system? Then obfuscation wouldn't matter--whatever munging is done to a particular image would produce the same OCR strings, before and after bayes training. You wouldn't need to know particular strings to match beforehand in that case. That would force image spammers would to produce a unique obfuscated graphic for every single message, which seems like an expensive proposition. Of course, I once thought producing a unique set of (text) bayes poison for every message was expensive, and that sure didn't stop them... ---- Nels Lindquist <*> Information Systems Manager Morningstar Air Express Inc. _______________________________________________ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.
