Audio Watermarking Based on Music Content Analysis: Robust against Time Scale Modification

摘要: Synchronization attacks like random cropping and time scale modification are crucial to audio watermarking technique. To combat these attacks, a novel content-dependent temporally localized robust method is proposed in this paper. The basic idea embed detect watermark selected high energy local regions that represent music transition drum sounds or note onsets. Such correspond edge will not be changed much for the purpose of maintaining auditory quality. In way, embedded expected escape damages caused by signal processing, etc, as shown experimental results.
