摘 要:在空间数据应用环境中,将空间对象作为一种新的客体类型实施访问控制的需求日益增强。其访问控制模型的研究大多在传统数据访问控制模型的基础上进行空间扩展,添加主、客体的空间属性,提供对空间操作的支持,对空间客体进行细粒度授权控制。在对空间数据访问控制模型进行深入研究的基础上,总结现存模型的技术渊源、相互关系、发展脉络,并重点从3种经典访问控制模型的空间扩展出发,以几种典型空间数据访问模型控制为例进行详细剖析,分析各种空间数据访问控制模型的技术特点及优、缺点,从而提出空间数据访问控制模型的独特需求,为进一步研究提供依据。In the scene of spatial data applications,there is an increasing need to implement access control to spatial object.Most of the research result on spatial data access control model is based on the traditional data access control model.It is focused on implementing spatial expansion based on the traditional data access control model,adding the spatial attributes of the subject and object,providing the support for the spatial operation,and realizing the fine-grained authorization of the spatial object.Based on the deep research on the spatial data access control model,this paper summarizes the technical origin,the interrelation and the development context of the existing models.Starting from the spatial expansion of the three classical access control models,this paper focuses on the analysis of several typical spatial data access control models.After that,the paper analyzes the technical features,advantages and disadvantages of various spatial data access control models,and proposes the unique research demands for a spatial data access control model,which could provide the basis for the further study.
