Abstract

Aiming at the poor robustness and transparency of color image watermarking algorithm, this paper proposes an improved color image watermarking algorithm based on DWT. The watermark image and the original image are transformed by DWT, and the embedding position of the watermark is adjusted according to the frequency sensitivity and color sensitivity of human visual system, so as to improve the robustness and transparency of the watermark algorithm. At the same time, the technology also uses Arnold scrambling encryption to ensure the security of the watermark. The simulation results show that the improved color image algorithm based on DWT proposed in this paper can effectively improve the transparency and robustness of the watermark, while ensuring the security of the watermark.
