%X The robustness of digital watermarking to various attacks is a focus of researchers, while geometric attacks are very common attacks in practical applications. But conventional watermarking algorithms are helpless in face of geometric attacks, so the robustness to geometric attacks is called a bottleneck of commercial digital watermarking. The existing typical watermarking algorithms robust to geometric attacks are summarized, then they are compared and analyzed from the points of theoretical analyses and experimental validations. The possible development trends are pointed out, which can instruct the development of watermarking algorithms resistant to geometric attacks.
