	abstract = {Copyright protection and authentication of digital contents have become a significant issue in the current digital epoch with efficient communication mediums such as Internet. Digital watermarking technique is now one of the hot research fields of copyright protection for CAD graphic data under the network environment. But there are very limited techniques available for that because of its high shape-preserving demand. Zero-watermarking is such a good means to deal with it and it has lots of advantages such as high capacity, good robustness and various functions. In this paper, we will discuss zerowatermarking algorithm for CAD models and eventually propose a watermarking-based digital rights management system that would test our techniques.},
