EAGER: Interfaces to Reduce Human Error in Social Network Access Control Policy Authoring

Internet的发展意味着从系统管理员到普通用户的每个人都经常面临如何共享数据的决策。研究表明，使用当前的访问控制机制，即使是专家也很难准确地做出这些决定。随着用户开始跨社交和专业应用程序共享信息，帮助防止此类语义错误的可用访问控制机制变得更加紧迫。这个项目开发了一个交互式创作范例，帮助用户在策略不一致变成语义错误之前识别和澄清它们。设想的工具在编写过程中检查策略及其后果，提醒用户注意潜在的不一致（例如，比大多数其他文档更全局共享的孤立文档），并提出问题以消除歧义。构建这种主动创作工具的挑战在于知道要跟踪哪些不一致和问题，同时又不会让用户感到太多的交互。因此，建议将用户研究与工具构建和评估结合起来。这个项目的智力价值在于它将用户行为研究和逻辑工具结合起来，产生了一种新的策略制定范式。在对社交网络用户进行人种学研究的指导下，为主流终端用户构建工具将产生更广泛的影响。欲了解更多信息，请参阅项目网站的URL: http://www.margrave-tool.org/

The growth of the Internet means everyone from system administrators to casual users are regularly confronted with making decisions on how to share data. Research suggests that even experts struggle to make these decisions accurately using current access-control mechanisms. As users start to share information across social and professional applications, usable access-control mechanisms that help prevent such semantic errors are all the more urgent. This project develops an interactive authoring paradigm that helps users identify and clarify policy inconsistencies before they turn into semantic errors. The envisioned tools examine policies and their consequences during authoring, alert users to potential inconsistencies (such as isolated documents shared more globally than most others), and ask questions in order to eliminate ambiguities.The challenge in building such proactive authoring tools lies in knowing what inconsistencies and issues to track without overwhelming a user with too much interaction. The proposal therefore combines user studies with tool building and evaluation. The intellectual merit of this project lies in its marriage of research on user behavior and logical tools to produce a new paradigm of policy authoring. Broader impacts come from building tools for mainstream end-users, guided by ethnographic studies of social-network users.
