Improved Audio Steganographic Method
- Summary
- 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.

- *Background
- Audio steganography, hiding digital data in audio signals, is gaining widespread acceptance for watermarking of materials. An ideal steganographic system is expected to meet three key requirements, namely imperceptibly of embedding, correct recovery of embedded information, and large payload. Current steganographic systems do not meet the large payload requirement.
