| Abstract: |
| With the rapid development of computer,network and communication,espically the popularization of the Internet, information security and protection have become a key and attractive problem.Digital watermarking is an effective method for copyright protection,but it may easily be attacked and destroyed,so that the watermark is undetectable.The robustness measuring of digital watermarking under different attacks is studied, and regarding the Stirmark software as standard measuring tool, quantitative analysis of the robustness of Digamarc watermark on the signal process Transformation and geometric transformation attacks is made.The results can help design and improve watermarking algorithms holding better security and robustness. |
