| Research Abstract |
An audio watermarking method based on spatial masking, which is a phenomenon observed in the human auditory system and had not been used in audio watermarking methods, has been developed. At the initial stage of the study, correct reproduction of sound space via headphones was investigated. The watermarking method was then devised, placing a watermark signal in the vicinity of the host signal by the use of an audio format which is capable of rendering sound space more precisely than the ordinary stereo format.
