浅析三维图形中的信息隐藏技术

Analysis of information hiding technology in 3D graphics

目前对三维图形作品的知识产权的保护与重要信息加密隐藏的需求日益增长,人们开始使用隐藏技术为三维数字化作品添加数字水印或通过三维图形信息隐藏技术加密重要信息。文章对三维图形中的信息隐藏技术作了剖析,并对基于距不变特征的隐藏算法进行了研究,最后利用ply格式的三角形网格Cow三维模型对算法进行了验证。

Since the protection of intellectual property in 3D graphics and encryption of information are more and more important, people began to use the information hiding technology to add a digital watermark or to use 3D graphics information hiding technology to encrypt important information. The information hiding technology in 3D graphics is introduced in this paper and the hiding algorithm based distance-invarianee is investigated. Finally the algorithm is verified by triangular grid Cow 3D model in ply format.
