| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The audio watermarking method, “the audio watermarking method based on amplitude modification,” has been proposed by W. N. Lie as a prevention technique against copyright infringement. We have increased the capacity of watermark information by embedding multiple watermarks. However, the multiple embedding causes the deterioration of sound quality. And hence, we propose the sound quality improvement method focused on the DC component which is not perceived by human ears. From experimental results, we confirmed that the subjective sound quality was improved as the robustness was maintained. | |
