提出一种新的基于Logi8tic加密的鲁棒性盲检测数字水印算法.利用Logistic映射特性产生的混沌序列加密生成水印序列;结合人眼的视觉系统(HVS)对原始图像中的子块进行选择;在每个被选择的子块上,根据鲁棒性要求选择DCT系数;通过对相邻系数对的大小进行比较嵌入水印.实验结果表明,本算法具有鲁棒性强、安全性高、透明性好、可以盲提取等特点,可有效用于数字媒体的版权保护.

A new robust blind detection digital watermarking algorithm based on Logi8tic encryption is proposed. The chaotic sequence generated by the logistic mapping feature is used to generate the watermark sequence. Combined with the visual system (HVS) of the human eye, subblocks in the original image are selected; On each selected subblock, DCT coefficients are selected according to robustness requirements; The watermark is embedded by comparing the size of adjacent coefficient pairs. Experimental results show that the proposed algorithm has the characteristics of strong robustness, high security, good transparency, and blind extraction, and can be effectively used for copyright protection of digital media.
