Özet
The usage of watermarking has increased recently due to the increasing concern on copyright content protection. Audio watermarking is a more challenging task because it is more easily detected. This paper presents a digital audio watermarking scheme based on frequency hopping spread spectrum technique on wavelet domain to embed the water-mark. Before embedding, the watermark is spread with the Direct Sequence Spread Spectrum (DSSS) technique. The experimental results demonstrate that the embedding technique is more audible, but more robust against the common signal processing attacks like low-pass filter, adding white Gaussian noise, shearing, and compression. © 2013 IEEE.
