N. AOKI · IEICE Transactions on Communications · 2007
This study proposes a technique of lossless steganography for G.711, the most common codec for digital speech communications systems such as VoIP. The proposed technique exploits the characteristics of G.711 for embedding steganogram information without degradation. This paper shows the capacity of the proposed technique.
