Abstract(in English) | This paper presents a digital watermark scheme for high quality audio data. It is consistituted with frequency hopping by random key sequence and embedding of watermark by the modified discrete cosine transform. The watermark signal is uniformly spread over the whole window frame when it is embedded to sound, and the watermarked noise is suppressed in very low level. Therefore, the sound quality is attained more than 40dB in the segmental SN ratio by our scheme. The frequency hopping scheme brings us a robust watermark for copyright protection, thus the watermark is proof against such attacks as bandpass filtering, amplification and lossy compression. |
