Abstract
The issue of ownership of digital watermark is addressed in this paper. An audio watermarking scheme is presented where the biometric pattern of iris is used to generate the watermark that has a stamp of ownership. The watermark is embedded in the high-energy regions selectively, which makes the embedding process robust against cropping and synchronization attacks. Experimental results of listening evaluation and robustness tests have confirmed that the proposed scheme maintains good perceptual property and offers strong resistance to typical signal processing attacks.
