Naofumi Aoki · 2008
This study proposes a technique of lossless steganography for G.711, the most common codec for digital speech communications such as VoIP (Voice over IP). The proposed technique in this study exploits the characteristics of G.711 for embedding steganogram information without any degradation. This paper shows the capacity of the proposed technique.
