The Audio Watermarking method Using the MPEG-2 AAC Psychoacoustic Model

MPEG-2 AAC 심리음향 모델을 이용한 오디오 워터마킹 기법

In this Paper, we Present a method for embedding digital watermarks into digital audio signals. The watermarking must be imperceptible and should be robust to attacks, such as filtering and compression etc. In our method, we adaptively embedded the watermarks changing the scale factor using the spread spectrum and MPEG-2 AAC psychoacoustic model.
