Security Model for Distributed GIS Spatial Data

  title={Security Model for Distributed GIS Spatial Data},
  author={Zhang Yanqun and Wang Qianping},
  journal={2008 International Symposium on Information Science and Engineering},
Security management of geospatial data is a relatively unsolved problem in Geographical Information Systems. In this paper a new storage model for distributed GIS spatial data based on object-based storage (OBS) has been constructed, which gives an integrated solution to both offer high-performance storage services and secure data sharing. The mechanism is composed of three security protocols: GIS server-security manager protocol, security manager-OBSD(OBS Device) protocol and GIS Server-OBSD… CONTINUE READING
