A Robust Audio Aggregate Zero-Watermark Algorithm

This paper proposes an audio aggregate watermark algorithm based on cloud model, Break through the traditional watermarking which only works to a single audio, implement copyright protection for an audio aggregation. In view of particularities of audio aggregation, experiment not only takes traditional attacks on audio works in aggregation, but also takes joint attacks and audio number change attacks. Experimental results show that the proposed algorithm can protect copyright of all audio in audio aggregation at the same time, it is robust to attacks such as traditional attacks, joint attacks and number change attacks.
