Category: Outlook Group: None Status: Open Priority: 5 Submitted By: Paul Grunwald (pgrunwald) Assigned to: Mark Hammond (mhammond) Summary: Graphic Hash score? Initial Comment: I upgraded to the latest version and the majority of the spam that is getting through is a graphic that is an ad for perscription drugs. The bottom of the spam is a random word list to confuse the lexical scores. Would it be possible to develop another score that perhaps took a bit hash of the graphic in the spam and then looked for the same hash on subsequent messages? A more complicated solution would be to look for "similar" pictures but I would think this would be an order of magnitude more complicated than a simple hash or other calculation. Other things that could contribute to the score could be size, shape, color depth, percentage of white space or background color, etc. I know that it would be somewhat easy to put in a random bit in the graphic to cause a different hash but it would put a CPU tax on the spammers to randomize the graphics for every message. Just a thought, Paul ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=498106&aid=1233040&group_id=61702 _______________________________________________ Spambayes-bugs mailing list [email protected] http://mail.python.org/mailman/listinfo/spambayes-bugs
