摘　　要：在实际生活中,随着人们所处空间位置的变化,其扮演的角色也会相应发生改变。基于位置的服务作为IT信息服务的重要内容,它根据用户所处空间位置向其提供在当前环境下所需的数据信息。为了保护隐私,保证数据资源不被非法利用,迫切需要对基于移动用户位置的信息服务中的访问控制模型技术进行研究。对现有的具有代表性的空间访问控制模型作了介绍,并进行了分析比较,探讨了在空间访问控制模型的进一步研究中需要解决的关键问题。In the real life, the playing role of everyone is changed when the physical location of this man/woman is located in another different spatial extension. Location-based service is the essential element of the IT information service. It provides the requested data to the authorized user who is authenticationed based on his/her physical location. In order to protect users privacy and stop the illegal using of protected data, it is urgent to promote the study of the novel access control model of the location-based service based on the spatial location of each mobile user. Several representative spatial access control models were studyed and compared in details. Some key problems which must be resolved in the future study were listed and briefly discussed.
