本文介绍了如何隐私策略框架可以扩展与定时信息，不仅决定是否允许在给定的时间点的数据请求，但也决定多久这样的权限被授予。使用过期信息来扩充策略决策，消除了在每个单独的数据访问操作之前对访问权限进行推理的需要。这有利于隐私政策框架的应用，以保护多媒体流数据，重复重新计算的政策决定是不是一个可行的选择。我们展示了如何将定时信息集成到现有的声明性隐私策略框架中。特别是，我们讨论了如何获得有效的到期信息中存在的复杂的一套政策与潜在的相互作用的政策和不同的时间信息。
This paper describes how a privacy policy framework can be extended with timing information to not only decide if requests for data are allowed at a given point in time, but also to decide for how long such permission is granted. Augmenting policy decisions with expiration information eliminates the need to reason about access permissions prior to every individual data access operation. This facilitates the application of privacy policy frameworks to protect multimedia streaming data where repeated re-computations of policy decisions are not a viable option. We show how timing information can be integrated into an existing declarative privacy policy framework. In particular, we discuss how to obtain valid expiration information in the presence of complex sets of policies with potentially interacting policies and varying timing information.
