As to the feasibility of detecting steganography, there is a fair amount of work on the subject, e.g.: http://www.jjtc.com/Steganalysis/ http://www.securityfocus.com/infocus/1684 http://en.wikipedia.org/wiki/Steganography http://www.guillermito2.net/stegano/ And see the references in the Wikipedia article. > Mark Allums Celejar -- mailmin.sourceforge.net - remote access via secure (OpenPGP) email ssuds.sourceforge.net - A Simple Sudoku Solver and Generator -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
