A Lossless Steganography Technique for Speech Codec Based on Nonlinear Quantization
Naofumi Aoki (Hokkaido Univ.) NLP2007-141
Abstract (in Japanese) (See Japanese page) 
(in English) 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.
