Multiple Digital Watermarking Techniques for CAD Models
Digital watermarking technique is becoming one of thehot research fields of copyright protection for CAD graphic data under the network environment. Along with its development there came a new technique called multiplewatermarking. It combines several single watermarkingalgorithms and has lots of advantages such as high capacity, good robustness and various functions. In this paper we will discuss several watermarking techniques for CAD models and eventually propose a multiple watermarking-based digital rights management system that would test our techniques.
