Abstract :
This work proposes an audio zero-watermark algorithm which combined DCT and Zernike Moments. The proposed algorithm combines a part of samples and low-frequency DCT coefficients of the same volume to perform low-order Zernike transform, and then construct watermark based on Zernike moments. Experimental results show that the proposed algorithm can resist both common signal processing and geometrical attacks effectively.
