CT-M: Collaborative Research: Securing Dynamic Online Social Networks

考虑到社交网络系统的流行和广泛采用以及这些系统提供的竞争优势，在分布式和/或联邦环境中使用这些系统访问、存储和交换个人属性信息的情况迅速增长，并且预计这一趋势将继续下去。高效、安全和以用户为中心的技术对于成功部署此类系统非常重要。我们在这个项目中的目标是开发一个全面而引人注目的框架SNGuard (Social Network Guard)，它可以满足各种隐私属性、访问控制问题、身份管理需求和使用模式。动态社交网络的愿景是一个复杂而高度复杂的愿景，需要不断进行研究和分析，以继续与数字信息的创造和使用（包括社交网络中的个人信息和内容）的角色和面貌的变化同步。该项目产生的主要智能产品将是开发新的框架，以促进以用户为中心的隐私管理、内容管理和风险感知访问控制，从而使SNGuard解决方案更值得信赖、更可靠、更不容易受到攻击。这一研究成果将产生广泛的社会影响，因为它提供了一种关键机制，使新的商业和社区模式能够在网络空间中安全、轻松、快速地建立个人属性（包括身份信息）共享的社会网络环境。除了这些潜在的好处之外，这项研究还将促进其他预期的、广泛的好处，包括对K-12教育、国际合作以及工业和政府合作伙伴的重大影响。

Considering the popularity and wide adoption of social network systems and the competitive edge these systems provide, there has been a rapid growth in use of these systems to access, store, and exchange personal attribute information in distributed and/or federated environments and this trend is expected to continue. Efficient, secure, and user-centric techniques are important for the successful deployment of such systems. Our goal in this project is to develop a comprehensive and compelling framework SNGuard (Social Network Guard) that satisfies diverse privacy properties, access control issues, identity management requirements, and usage patterns. The vision of dynamic social networks is a complex and highly sophisticated one that requiring ongoing research and analysis to continue concurrent with the changing role and face of digital information creation and usage including personal information and contents in social networks. The principal intellectual products resulting from this project will be the development of novel frameworks to facilitate user-centered privacy management, content management and risk-aware access control, thereby making SNGuard solutions more trustworthy, more reliable, and less vulnerable. This research effort will have broad societal impact by providing a key mechanism to enable new business and community models for the sharing of personal attributes including identity information to safely, easily, and quickly establish social networking environments in cyberspace. In addition to these potential benefits, other anticipated, broad-based benefits to be facilitated by this research include significant influence to K-12 education, international collaboration, and industrial and government partners.
