摘　　要：提出了一种基于特征点的双数字水印方案.该方案将原始水印转换为与图像内容相关的两个水印,通过混沌序 列分别嵌入到特征点区域中.在进行水印检测时,同时检测出两个水印,恢复出原始水印图像.该方案在考虑数据压缩和几 何攻击的同时,也对解释攻击(IBM攻击)进行了一定的应对.实验结果与理论分析表明,该方案具有较好的强壮性.This paper presents a new watermarking scheme of digital images based on the feature points. In this scheme, the original watermark can be converted into two watermarks interrelated with digital image and then be embedded into the circumjacent area of feature points through chaos sequence. When checking, two watermarks are checked at the same time, and the original watermark can be resumed. Experimental results and theoretic analyses show that the scheme can stand against several attacks, such as image compression, geometric attack, IBM attack, etc.
