Abstract:A simple and effective audio watermarking algorithm based in time domain is proposed in this paper for controlling the unauthorized distribution of copyright audio. The algorithm makes use of the advantages of both embedding a watermark bit to an individual sample and embedding a bit to a group or frame of samples. Here, a frame of three positive valued samples is used to define the amount of distortion to be added but only the middle sample is distorted based on the decision. Based on the watermark bit either… Show more
