摘要

最近,人们每天花费大量时间在社交网络活动中,因此人们创造了大量的信息,这引发了许多隐私和安全问题。虽然在线社交网络允许用户通过指定谁可以访问他们自己的共享数据来配置他们的隐私设置,但他们不允许用户定义应该访问他们的共享数据的上下文。为了使在线社交网络中的访问控制机制更加动态和灵活,我们提出了一种基于t - jclassic δ λ的基于上下文属性的访问控制,以表达比现有模型更细粒度的访问控制策略,因此使用我们的模型,用户可以根据时间上下文指定他们的隐私设置。

A contextual attribute based access control model based on T-JClassicδ∊
Recently, people spend plenty of times daily in social network activities, hence a large amount of information is created by people which move up a number of privacy and security issues. While online social networks allow users to configure their privacy settings by specifying who may access to their own shared data, they do not enable them to define the context under which their shared data should be accessed. In order to make the access control mechanism more dynamic and flexible in online social networks, we propose a contextual attributed based access control based on T-JClassicδϵ to express much more fine grained access control policies than the existing models, so using our model, users can specify their privacy settings based on temporal context.
