Overview of Digital Watermarking Techniques Against Geometric Attacks
Fuhao Zou · Computer Engineering and Science · 2006
Although we have made great progress in the research of robust watermarking techniques, how to resist the geometric attacks is one of the most difficulties in the watermarking field. So the research of watermarking techniques against geometric attacks has now become a focus. And many algorithms are proposed, which fall into two classes: the first and second generation watermarking schemes. In this paper the current methods against geometric attacks are surveyed and analyzed, and the advantages and disadvantages of each class are summarized, and some probable development directions are presented.
