| Outline of Final Research Achievements |
For audio signals, the sound quality of the stego signal should not deteriorate. We examine an embedding method from the following different viewpoint. There is no problem even if another sound, not in the original signal, is perceived when the sound of the stego signal is musical. In this case, we can regard the sound quality of the stego signal as high in this work. Accordingly, we focus on consonance of music theory, and propose embedding methods using sound source localization and non-negative matrix factorization. It was confirmed the validity of these methods from evaluations of tolerance and sound quality.
