摘      要：We propose a new quantum watermarking scheme based on threshold selection using informational entropy of quantum *** core idea of this scheme is to embed information into object and background of cover image in different ***,a threshold method adopting the quantum informational entropy is employed to determine a threshold *** threshold value can then be further used for segmenting the cover image to a binary image,which is an authentication key for embedding and extraction *** a careful analysis of the quantum circuits of the scheme,that is,translating into the basic gate sequences which show the low complexity of the *** of the simulation-based experimental results is entropy difference which measures the similarity of two images by calculating the difference in quantum image informational entropy between watermarked image and cover ***,the analyses of peak signal-to-noise ratio,histogram and capacity of the scheme are also provided.
