Abstract :
Steganography can be employed for transmitting side information improving 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 investigates the possibility of lossless steganography techniques for G.711 and DVIADPCM, the codecs employed in IP telephony services. The proposed techniques in this study exploit the redundancy of the folded binary code employed in these codecs for embedding steganogram information into speech data without degradation.
