| Abstract(in English) | For audio signals, the sound quality of stego signal should not deteriorated as much as host signal. With current methods, high sound quality means that the difference between the host and stego signals is small. On the other hand, high sound quality means that the sound quality of stego signal is maintained as music even if another sound, except for host signal, is perceived in this paper. According to this definition, the watermarks are embedded using non-negative matrix factorization. NMF is an algorithm that factorizes a non-negative matrix that is an amplitude spectrogram of host signal into two non-negative matrices that corresponds to the spectral patterns of the host signal and the activation of each spectrum. In this paper, a basis matrix of watermark signal separation is different from that of host signal separation. The watermarks are embedded by the magnitude comparison of activation matrix coefficients of watermark signal corresponding to root and dominant notes. It is considered that the components of watermark signal can be only extracted from the stego signal, because the basis matrices of host and watermark signal are different. We conduct an evaluation of the tolerance against attacks and an objective evaluation of sound quality, and confirm the validity of proposed method. |
