Technologies for 3D Model Watermarking: A Survey

Due to the explosive growth of Internet and the development of digital content designing and processing techniques, many valuable materials can be represented in digital forms for exhibition and access via Internet. Due to the characteristics of easy duplication and modification of digital contents, it is necessary to develop a variety of watermarking techniques for various protection purposes such as ownership claiming and authentication. In this survey paper, we examine 3D model watermarking technologies developed over the last decade. We classify various algorithms into two classes: robust watermarking and fragile watermarking. We describe main ideas behind each class, and compare the advantages and disadvantages of the algorithms in each class. Finally, we address some trends in the 3D model watermarking technology development.
