Little attempts have been done on adopting a watermarking technique for Internet Audio Streaming Service. In this paper, we integrate an audio watermarking technique to MPEG-2 AAC Audio Streaming Service. Our novel audio watermarking scheme using linear prediction based watermarking embedding and extraction is robust to common signal processing attacks. We design and implement a simple packet loss recovery algorithm for the robust extraction of watermark data, and design a business model for Internet audio streaming service. Experimental results show that our future AAC Streaming Service can safely protect the streaming audio contents from any kinds of unauthorized copy or reproduction.
