量子图像鲁棒零水印算法

Key Points

• The central aim is to develop a robust and imperceptible zero watermarking algorithm for quantum images.
• Proposal of a novel enhanced quantum representation (NEQR) model.
• Development of corresponding quantum circuits for the algorithm.
• Comparison of pixel gray value averages to generate robust zero watermark features.
• The quantum circuit complexity is O(k), where k is the height or width of the square image.
• The algorithm shows significant advantages over classical computing methods.
• Demonstrates strong robustness against various types of attacks.
