Abstract

It is well known that encryption provides secure channels for communicating entities. However, due to lack of covertness on these channels, an eavesdropper can identify encrypted streams through statistical test and capture them for further cryptanalysis. Hence, the communicating entities can use steganography to achieve covertness. 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.
