Abstract:To prevent the abuse of low‐rate speech‐based steganography from threatening cyberspace security, the corresponding steganalysis approaches have been developed and received significant attention from research community. However, most existing steganalysis methods assume that steganography methods are known in advance, which in practice is impractical. That is why, in this paper, we present three blind detection schemes suitable for steganography in low‐bit‐rate speech streams. The first is based on mixed sampl… Show more
