Description: A Novel Audio Watermarking Algorithm for
Copyright Protection of Digital Audio
Abstract
Digital watermark technology is now drawing attention
as a new method of protecting digital content from unauthorized
copying. This paper presents a novel audio watermarking
algorithm to protect against unauthorized copying
of digital audio. The proposed watermarking scheme includes
a psychoacoustic model of MPEG audio coding to
ensure that the watermarking does not affect the quality of
the original sound. After embedding the watermark, our
scheme extracts copyright information without access to the
original signal by using a whitening procedure for linear
prediction filtering before correlation. Experimental results
show that our watermarking scheme is robust against
common signal processing attacks and it introduces no audible
distortion after watermark insertion.
