Leveraging device comfort for protection of shared documents

SavvyDox系统允许基于云模型的文档查看者和编辑者始终能够实时查看文档的最新版本。就目前而言，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。但是，目前的网络内容安全模型在创建和维护方面存在一定的滞后。除了针对媒体消费的基于位置的DRM之外，几乎没有什么可以保留内容的可用性，或者在文档创建、编辑等方面的不同特权，以一种细粒度的方式来考虑移动设备上内容的社交和更传统的位置方面。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，与目前的情况相比，SavvyDox工具将受益于更具体的设备（上下文）信任视图。该项目通过为SavvyDox访问的云中文档的位置、社交和细粒度权限管理开发新颖的解决方案，解决了该公司的具体问题，并且是将Device Comfort模型完全集成到SavvyDox工具的先驱。

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.
