Key Technologies and Methods for Vector Geographic Data Security Protection

In recent years, vector geographic data have been widely used in fields of government, national defense, land, transportation, and marine. Vector geographic data are facing increasingly serious security threats in the process of storage, transmission and sharing. The contradiction between the security protection of vector geographic data and data sharing has become one of the key issues restraining the development of geographic information industry. Considering the above concerns, in this paper it analyzes several key technologies and progresses in existing vector geographic data security protection such as data encryption, data watermarking, data scrambling, and information steganography, and discusses the technical challenges that vector geographic data security protection is facing from the methods and integration of new technologies. Combining with the current advances in the field of vector geographic data and cyberspace security, some important directions for future research and development, such as sensitive information measurement and local dynamic processing, are proposed, which provide some advices for the research and application development of vector geographic data security and data sharing.
