Audio watermarking technique based on Arnold transform

This study proposes audio watermarking scheme based on Arnold transform with discrete wavelet transform (DWT) singular value decomposition (SVD) methods. The value on of bit error rate (BER) is 0 and peak signal to noise ratio (PSNR) is infinite, represent the robustness of this system. Results show that our proposed system is robust and imperceptible by about 0.01 intensity. It is show that our proposed system can achieve correlation coeficient is 1, objective difference grade (ODG) is -0.0625 and BER is 0 at 0.01 intensity. For all types of music files in the different numbers of iteration, our system has BER of 0, CC of 1 and infinite PSNR.
