| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we propose an audio information hiding algorithm for a stereo signal, where the information is embeded in the phase difference between stereo channels. In the embedding side, the information is redundantly embedded at multiple distributed locations in the time-frequency domain for increasing robustness against attacks. In the detection side, the information is detected with the weighted-average of them. We also discuss how to generate a signal for syncronization in order to detect the first of the block in a blind manner. | |
