The SavvyDox system permits the viewers and editors of documents in a cloud-based model to be able to always see the most up to date version of a document in real time. As it stands, this is a significant step forward in distributed collaborative models, for instance in collaborative content creation or editing. However, the current security models of online content lag behind the creation and maintenance aspect. Other than a rather broad-based location-based DRM, targeted at media consumption, there is very little that can be done to reserve content availability, or different privileges on document creation, editing, etc. in a fine-grained manner that takes into account social as well as more traditional locational aspects of content on mobile devices. Introducing a fine grained locational model would allow the SavvyDox engine and content view a far greater flexibility, enabling users to both distribute content more widely whilst at the same time protect it more flexibly. Moreover, the SavvyDox tools would benefit from a generally more device-specific (contextual) view of trust than is currently the case. This project addresses this company specific problem by developing novel solutions for location, social, and fine-grained rights management of documents in the cloud accessed by SavvyDox, and is a precursor to full integration of the Device Comfort model to SavvyDox tools.

SavvyDox系统允许基于云的模型中文档的查看者和编辑者始终能够实时查看文档的最新版本。从目前的情况来看，这是分布式协作模型向前迈出的重要一步，例如在协作内容创建或编辑方面。然而，目前网络内容的安全模型滞后于创建和维护方面。除了针对媒体消费的相当广泛的基于位置的DRM之外，在以细粒度的方式保留内容可用性或文档创建、编辑等上的不同特权方面可以做的很少，该方式考虑了移动设备上的内容的社交以及更传统的位置方面。引入细粒度的位置模型将使SavvyDox引擎和内容视图具有更大的灵活性，使用户能够更广泛地分发内容，同时更灵活地保护内容。此外，SavvyDox工具将受益于比目前情况下更特定于设备(上下文)的信任视图。该项目通过开发用于SavvyDox访问的云中文档的位置、社交和细粒度权限管理的新型解决方案来解决这一公司特有的问题，并且是将设备舒适度模型完全集成到SavvyDox工具的先驱。
