Abstract
In this chapter, an efficient and secure audio crypto-watermarking algorithm is proposed. In the proposed algorithm, multiple watermarks are first combined into a single fused watermark using the wavelet fusion, to increase the capacity of the embedded information in the audio signal. Then, the fused watermark is encrypted and embedded in the audio signal to improve the security of the embedded information. The experimental results prove that the wavelet fusion is an efficient algorithm to combine two images and improve capacity without affecting the audio signal. Also, the results indicate that the proposed crypto-watermarking algorithm is able to achieve the audio watermarking requirements without affecting the quality of the audio signal.
