| Abstract(in English) | We have proposed a novel audio watermarking technology, which embeds a set of bitstream data by changing two-channel stereo locations of lower frequency components in an embedding target audio signal. This method features nearly lossless embedding, robustness against lossy data compression or analogue conversion, and enables contactless asynchronous detection of embedded watermarks through speaker and microphone devices without the original audio signals. Then, we propose several extended monaural embedding methods, which enable watermark detection by a single monaural microphone or cellphone. In this paper, we describe an abstract of our proposed watermark embedding and extracting algorithm, and experimental results of watermark extraction precision. |
