数字版权管理允许信息所有者通过机器可读许可证控制电子文档的使用和传播。本文描述了一个系统的设计和实现，该系统用于创建和执行包含位置约束的许可证，该位置约束可用于将对敏感文档的访问限制在定义的区域。文档可以加载到便携式设备上并在批准的区域中使用，但如果设备移动到其他区域则无法使用。我们的贡献包括在存在执行非瞬时受控操作的请求时进行访问控制的分类。
Digital rights management allows information owners to control the use and dissemination of electronic documents via a machine-readable licence. This paper describes the design and implementation of a system for creating and enforcing licences containing location constraints that can be used to restrict access to sensitive documents to a defined area. Documents can be loaded onto a portable device and used in the approved areas, but cannot be used if the device moves to another area. Our contribution includes a taxonomy for access control in the presence of requests to perform non-instantaneous controlled actions.
