However, with the development of digital watermarking technology, attackers have also begun to use various means to crack digital watermarking, making the robustness and security of traditional digital watermarking technology more important. This paper proposes a dynamic quantization robust digital watermarking algorithm based on pre-attack, which can quantize the embedded digital watermark in the pre-processing stage of the attack, and after successfully embedding the digital watermark, the digital watermark can be adaptively adjusted according to the attack type and intensity, improving the robustness and security of the digital watermark. Experimental results show that the algorithm can effectively resist common attacks, such as blind attacks, interference attacks, and filtering attacks.Keywords: digital watermarking; robustness; pre-processing; quantization; adaptive
