- W2055895958 abstract "Geospatial data is important strategic information for economy development, social development, and even for national security; therefore, it is important to protect the copyright of spatial data files. Compared to the focus on digital rights management for e-books, streaming media, research on copyright protection for spatial data files is relatively less. This paper first describes the basic principles of digital rights management, and then presents a digital rights management model for spatial data files based the copyright protection needs and characteristics of spatial data files. 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 to protect the copyright of spatial data files. This paper also detailed analyzes the key technologies which are used to implement the proposed model." @default.
