A Robust Audio Digital Watermarking Algorithm based on Psychoacoustics Model

Digital watermark technology is now drawing attention as a new method of protecting digital content from unauthorized copying. A novel audio watermarking algorithm is used to protect against unauthorized copying of digital audio. Watermarking scheme includes a psychoacoustics model to ensure that the watermarking does not affect the quality of the original sound. The watermarking scheme is robust against common signal processing attacks and it introduces no audible distortion after watermark insertion
