Abstract: | In this paper, we propose a new robust and blind audio watermarking algorithm based on singular value decomposition and quantization
index modulation. The watermark insertion and extraction methods are based on quantization of the norm of singular values
of the blocks. Audio quality evaluation tests show high imperceptibility of the watermark in the audio signal. Simulation
results demonstrate that this algorithm is robust against signal-processing and stirmark attacks. The false negative error
probability under the proposed scheme is close to zero. Moreover, the proposed algorithm has higher data payload and better
performance than the other related audio watermarking schemes available in the literature. |
