A robust audio watermarking based-on multiwavelet transform
2009 / IEEE / 978-1-4244-2564-8
This item was taken from the IEEE Conference ' A robust audio watermarking based-on multiwavelet transform ' In this paper, a robust watermarking scheme for digital audio signal is proposed. The watermarks are embedded into the low frequency coefficients in discrete multiwavelet transform domain to achieve robust performance against common signal processing procedures and compression. The embedding technique is based on quantization process which does not require the original audio signal in the watermark extraction. The experimental results demonstrate that watermark is imperceptible and the algorithm is robust to many common signal processing procedures, such as re-sampling, cropping, low-pass filtering and MPEG 1 Layer III compression.
