| Summary: | In this paper, a robust wavelet based watermarking scheme has been proposed for digital
audio. A single bit is embedded in the approximation part of each frame. The watermark bits are
embedded in two subsets of indexes randomly generated by using two keys for security purpose. The
embedding process is done in adaptively fashion according to the mean of each approximation part.
The detection of watermark does not depend on the original audio. To measure the robustness of the
algorithm, different signal processing operations have been applied on the watermarked audio.
Several experimental results have been conducted to illustrate the robustness and efficiency of the
proposed watermarked audio scheme. |
