Abstract :
Digital watermarking is considered as an efficient way to protect copyright of digital products. According to human auditory system (HAS), digital audio watermarking will be performed well by making use of auditory masking. Binary watermark information was embedded by classical quantization method in DCT domain after scrambled by logistic map in chaos theory. Based on HAS and chaos theory, the proposed method is transparent and robust, especially for most of attacks in STIRMARK.
