Research on Watermark Signal of Public-key Digital Watermarking Scheme
Hu Yan · Acta Scientiarum Naturalium Universitatis Sunyatseni · 2004
A public_key robust watermarking scheme has more potential value of application. A signal with with special auto_correlation characteristic is proposed. Also a public_key robust watermarking scheme based on this signal is designed and experimented. The experiment result shows the scheme is valid and robust to common signal distortions and malicious attacks.
