Digital audio watermarking technique using Pseudo-Zernike moments

Abstract

Based on Pseudo-Zernike moments and synchronization code, we propose a new digital audio watermarking algorithm with good auditory quality and reasonable resistance toward de-synchronization attacks in this paper. Simulation results show that the proposed watermarking scheme is not only inaudible and robust against common signals processing such as MP3 compression, noise addition, re-sampling, and re-quantization etc, but also robust against the de-synchronization attacks such as random cropping, amplitude variation, pitch shifting, etc. © 2009 Springer-Verlag.
