摘要
公钥鲁棒性水印方法无疑是更具有应用前景的鲁棒性水印方案。提出了一种新的具有特殊相关特性的信号的产生方法;并以此信号为水印信号,实现了一种具有公钥鲁棒性数字水印方案。仿真实验结果证明基于该水印信号的公钥鲁棒性水印方案是可行的。
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.
