摘　　要：传统水印嵌入鲁棒性评估方法评估结果不可靠,为此,提出一种新的数字视频图像加密域水印嵌入鲁棒性评估方法。给出数字水印系统的一般模型。通过将明文域方法同态转移及调整,获取加密域水印嵌入方法,给出加密域水印嵌入方法详细实现过程。通过接收内容与水印信息间的互信息对接收信息所含水印信息进行描述,利用互信息函数实现数字视频图像加密域水印嵌入鲁棒性分析。实验结果表明,所提方法可有效评估数字视频图像加密域水印嵌入鲁棒性,和其它方法相比评估结果更加可靠。Therefore,a new robustness assessment method of watermark embedding in digital video image encryption domain is proposed. The general model of digital watermarking system is given. Through the homology transfer and adjustment of the clear-text domain method,we get the embedding method of the watermark in the encrypted domain,and give the detailed implementation process of the watermark embedding method in the encrypted domain. The watermark information contained in the received information is described by receiving the mutual information between the content and the watermark information,and the mutual information function is used to realize the robustness analysis of watermark embedding in the digital video image encryption domain. The experimental results show that the proposed method can effectively evaluate the robustness of watermark embedding in digital video image encryption domain,and the result is more reliable than other methods.
