A new fragile audio watermarking scheme

This paper proposes a novel fragile watermarking scheme for audio content authentication. The chaotic mapping based watermark information is embedded in the principal component of the detail wavelet coefficients of the host audio based on the instantaneous mixing model of independent component analysis system. The watermark can be extracted with Fast ICA technique, blindly. Experimental results demonstrate that the proposed scheme achieves excellent transparency, good fragility, and accurate tampering detection.
