要約

A real-time audio watermarking scheme is proposed in which the strength of the watermark, embedded into the audio signal is limited to produce a watermarked signal perceptually closely similar to the original one. The proposed scheme uses a spread spectrum approach to embed the watermark which is generated by using a private key, and a blind detection algorithm to extract the watermark from the watermarked audio signal. Real-time implementaciуn of proposed scheme is also given which only requires 70 MIPS. Evaluation results show that the embedded watermark is robust to common attacks such like D/A and A/D conversions, filtering, noise addition and high quality MPEG audio coding. Subjective and objective evaluation results are also given to show the quality of watermarked signal.
