All three, discrete wavelet transform (DWT)-singular value decomposition (SVD) and adaptive tabu search (ATS) have been used as mathematical tools for embedding data into an audio signal. In this paper, we present a new robust audio watermarking scheme based on DWT-SVD and ATS. After applying the DWT to the cover audio signal, we map the DWT coefficients, and apply the SVD, we search for the optimal...
This article presents the audio watermarking using multiple image-based watermarks based on genetic algorithms (GA) in the discrete wavelet transforms is proposed. Rather than using one watermark into a whole length of audio, we select appropriate watermarks in order to embed it into selected parts. It is robust against watermarking attacks, which are commonly employed in literature. In addition,...
