MP3-Resistant Audio-Adaptive Steganography

In this paper, we propose a novel audio steganography scheme for embedding high-capacity covert data in a music carrier, where the carrier is first transformed to a 2D arrangement (image) and represented by a wavelet domain singular value decomposition (SVD), and a quantization-index-modulation process is then applied on the SVD for the covert data embedding. The proposed scheme, due to its indirect embedding on the singular values in the visual domain, possesses a high and flexible embedding capacity and an excellent MP3 robustness while retaining good inaudibility. The MP3 robustness and the imperceptibility are further enhanced by adaptively modeling the quantization parameters based on the statistics within subbands.
