Centroid-based Robust Audio Watermarking Scheme

摘要：

In this paper, we propose a novel robust audio watermarking scheme based on DCT (Discrete Cosine Transform). The key point lies in the fact that centroid of each audio frame will not be changed much in order to maintain high auditory quality. Each audio segment carrying the centroid of one audio frame is performed with DCT. Then the direct-current component of each audio segment is embedded scrambled watermark bit by quantization method. The extraction process of the robust watermark doesn t need original audio signal. Experimental results show good transparency and high robustness against various common audio signal processing attacks of this scheme, and the stable essence of audio centroid under these various attacks.
