| Outline of Final Research Achievements |
In our multilayer type audio watermarking method, we increase the capacity of embedding by introducing multi-layered embedding process of watermark information. However, there is the problem that sound quality degradation is likely to be perceived according to multi-layered embedding process. In this research, we control the number of layers in multilayer type audio watermarking method according to the sound quality obtained by objective sound quality evaluation method with biological signal. As a consequence, we realized the balance of embedding capacity and sound quality.
