Liangbin Zheng, Ruqi Chen, Xiaojin Cheng · 2011
Vector graphics is an important form of multimedia information. Compared to the focus on digital rights management for e-books, streaming media, research on copyright protection for vector graphics is relatively less. This paper first describes the basic principles of digital rights management, and then presents a copyright protection model for vector graphics based on the copyright protection needs and characteristics of vector graphics. The proposed model makes full use of the advantages of encryption, digital watermarking and file system filter driver techniques, therefore avoids the shortcomings brought from relying solely on encryption or digital watermarking technology for copyright protection. This paper also detailed analyzes the key technologies of the proposed model.
