Improved Audio Watermarking Using DWT-SVD

Digital audio watermarking involves the concealment of data within a discrete audio file. Applications for this technology are numerous. Intellectual property protection is currently the main driving force behind research in this area. In this paper we present an ef- ficient audio watermarking algorithm in the frequency domain by embedding an inaudible audio water mark. Comparison of two different algorithms i.e. Discrete Cosine Transform (DCT)-Singular Value Decomposition (SVD) and Discrete Wavelet Transform (DWT)-SVD is presented here. The effectiveness of these algorithms is verified by conducting experimentation. Experimental results show that the wa- termarked audio has good imperceptibility and is robust against different kinds of attacks, such as noise adding, re-sampling, cropping.
