Study on Protection of Genuine Digital Music Works by a Watermarking Algorithm

The protection of genuine digital music works is critical. In this paper, a watermarking algorithm was designed based on the technique of discrete wavelet transform and vector norms to achieve the protection of music works. The experiments on different types of digital music works showed that the watermarking algorithm designed in this paper had good security, a high mean opinion score and signal-to-noise ratio, and good imperceptibility, and it kept a high normalized coefficient and low bit error rate in the face of noise addition and resampling attacks and had an embedding capacity greater than 20 bps. The results demonstrate the effectiveness of the designed watermarking algorithm in protecting genuine digital music works.
