Embedded Noise Reduction Technique for Auido Watermark Using Auditory Stream Segregation Phenomenon
Toshio Modegi, Makoto Chiba (DNP) EA2007-5
Abstract (in Japanese) (See Japanese page) 
(in English) We are developing audio watermarking techniques which enable extraction of embedded data by cell phones. For that we have to embed data onto frequency ranges, where our auditory response is prominent, therefore data embedding will cause much auditory noises. Previously we have proposed an applying two-channel stereo play-back feature, where noises generated by a data embedded left-channel signal will be reduced by the other right-channel signal. However, this proposal has practical problems of restricting extracting terminal location. In this paper, we propose an improved method, which supports monaural play-back operations. This proposes multiplexing the noise reducing right–channel signal with the left-signal and reduces noises completely by generating an auditory stream segregation phenomenon to users.
