Improved Audio Steganographic Method
總結
A researcher at Purdue University Calumet has developed a novel steganographic method that achieves imperceptible embedding and accurate data retrieval using the cepstral analysis method while allowing large payload capability. This method of embedding can be carried separately in either the vocal source or the vocal tract without affecting the other, which ensures perceptually oblivious embedding.
