摘    要:随着信息时代的到来,数字水印不仅在版权保护、来源认证、私有探测领域受到了前所未有的重视,而且在信息安全领域也引起了广泛的关注.提出了一种基于B-rep的CAD模型盲水印算法,该算法主要针对NURBS曲线或曲面来嵌入水印,能精确地保持模型的形状.首先遍历模型找到所有的NURBS曲线,并将其依据曲线的长度进行排序,然后利用...

关 键 词:数字水印  盲水印  三维CAD模型  NURBS基元  版权保护

Abstract:With the appearance of informatization period,digital watermarking is attached importance to a great extent in these facts such as copyright protecting,source authentication,private detection and on,and becomes one hot research field of information security.This paper proposes a blind watermarking algorithm based on B-rep for CAD models,the algorithm embeds watermarking aiming at NURBS surfaces or curves,and its merit is preserving the model's shape exactly.Firstly,we go through the model for obtaining all ...
Keywords:digital watermarking   blind watermarking   CAD models   NURBS primitives   copyright protecting
