doi:10.3724/SP.J.1087.2005.1277

Abstract

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

摘要： 针对空间数据的访问控制的特点,提出了基于空间索引的区域访问控制概念。定义了其授权和访问请求判断的规则和约束条件。给出了授权和访问请求判断的方法,建立了二维空间区域访问控制模型。

关键词: 空间数据, 访问控制, 空间索引, 空间区域
