| Abstract(in English) | A digital watermark is a technique to embed another digital data into digital contents such as music, image and movie. For audio signals, it is required that the sound quality of stego data is not deteriorated. In existing methods, the high sound quality means that the difference between host data and stego data is small. On the other hand, in this paper, there is no problem even if a different sound from host data is perceived when stego data is maintained as music. Accordingly, we make a countermelody using counterpoint and we have proposed a watermarking method that the countermelody is added to host data as watermark signal. In this paper, we introduce not only chord tone but also non-chord tone as an effective musical accent to watermark signal. Moreover, multiple tones can be arranged in one tone of host data, and an increase of watermark capacity is prospective. |
