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 waterma

Watermark A visible or invisible signature embedded inside an image to show authenticity or proof of ownership. The hidden watermark should be inseparable the host image, robust enough to resist any manipulations while preserving the image quality. T
