A novel audio aggregation watermarking for copyright protection

Abstract

A novel algorithm of audio aggregation watermarking was proposed in this paper for copyright protection. The algorithm not only protects copyright of a single audio in audio aggregation but also protects copyright of the whole audio aggregation. The experimental results showed the watermark of aggregate audio can resist to some attacks, for example, deleting audio, substituting audio and adding audio; at the same time, watermark of every single audio is robust to some attacks such as low-filtering, resampling, requantization, noise addition and mp3 compression. The proposed algorithm has good imperceptibility and strong robustness.
