Steganography may be employed for secretly transmitting side information in order to improve the performance of signal processing such as packet loss concealment and band extension of telephony speech. The previous studies employ LSB replacement technique for embedding steganogram information into speech data. Instead of such a lossy steganography technique, this study has investigated a loss less steganography technique for G.711, the most common codec for telephony systems such as VoIP. The proposed technique in this study exploits the redundancy of G.711 for embedding steganogram information into speech data without degradation. This paper newly investigates the possibility of a semi-loss less steganography technique for increasing the capacity of the loss less steganography technique.
