Abstract: Aim at the characters of spatial data access control, the concept of spatial region access control based on spatial index was proposed. The 2-D access control model of spatial data was presented. The authorization and access request rules and constraints of spatial region access control were defined, and the method of spatial data access control was described in detail.

Key words: spatial data, access control, spatial index, spatial region
