Digital Audio Watermarking Technique with the Use of Multiple DWT and DCT Transform

Abstract:

This paper describes an approach to watermarking an acoustic signal. The proposed solution employs previously known methods from the transform domain that are widely used in existing algorithms for watermarking multimedia files. The aim of the research is to develop a method to embed a digital signal processing operation-resistant and inaudible watermark and a method to extract the watermark flawlessly without having the original audio signal.
