| 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 focus on counterpoint and we have proposed a method to embed watermarks adding watermark signal into consonance of host data. The sound quality of stego data is not discomfort even if watermark signal is perceived because stego data is maintained as music. However, for embedding watermarks into consonance, we need to decide the key of host data. Hence, in this paper, we propose an audio watermarking method that watermarks are embedded into consonance suitable for host data by determination of key and root note. |
