摘要
访问控制是关联数据环境下保护敏感数据的重要技术,文章概述了访问控制策略和常用的策略语言,重点阐述分布式云平台授权、标注RDF、令牌和本体4种访问控制的改进方法。另外还介绍了在传统的访问控制模型的基础上的基于语义访问控制模型、基于关系的访问控制模型等改进模型,分析了Lockr,My Privacy Manager,RAW等典型的应用系统的组成和功能特点,最后讨论了衡量访问控制的一些标准。
Access control is an important technology to protect sensitive data in the environment of linked data. This paper summarizes the access control policy and common policy language,and focuses on 4 access control methods to improve the annotation,which are distributed cloud platform,annotated RDF,token and ontology. Furthermore,the paper introduces such improved models as semantic-based access control model and relationship-based access control,which are based on the traditional access control model. The paper also analyzes the composition and function of typical application system,such as Lockr,My Privacy Manager and RAW. Finally,the paper discusses some standards to measure the access control.
