DIGITAL WATERMARK BASED ON WAVELET TRANSFORM FOR AUDIO SIGNALS

摘要

This paper will present you a new method to embed watermark into audio signals. Watermarking is a technique used to label digital media by hiding copyright or some information into the target data. It is obvious that the watermark must be imperceptible by users and be robust to attacks and distortions. The method we discussed in this paper is based on wavelet transform and probability theories. We will also discuss the detection of the watermark and the robustness of the approach.
