[转载]Data Masking：A New Approach for Data Hiding
原始连接：[url]http://isis.poly.edu/memon/publications/pdf/2004_Data%20Masking_A_New_Approach_for_Data_Hiding.pdf[/url]In this paper we propose a new form of multimedia steganography called data masking. Instead of embedding a secret message into a multimedia object, as in traditional multimedia steganography, we process the entire secret message using an inverse Wiener filter to make it look like a multimedia object itself. Thereby we foil an eavesdropper who is primarily applying statistical tests to detect encrypted communication channels. We show that our approach can potentially give a covert channel capacity which is an order of magnitude higher than traditional steganography.
