Abstract :
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 protocol. These three protocols maintain integrity, confidentiality and privacy of distributed GIS spatial data.
