TWC SBE: Medium: Collaborative: Building a Privacy-Preserving Social Networking Platform from a Technological and Sociological Perspective

社交网络提供了许多好处，但也引起了对隐私的严重担忧。事实上，由于隐私保护本质上并没有整合到底层技术框架中，用户数据仍然可以被社交网络访问，并可能被滥用。虽然有人努力将隐私整合到社交网络中，但现有的解决方案不够轻量、透明和实用，因此只获得了有限的采用。该项目开发了一个保护隐私的社交网络（Trusted-Space），其中用户数据不受社交网络本身、其他社交网络用户和广告商的影响。该项目从技术和社会学的角度综合了解决方案，以确保用户和广告商有效参与社交网络所需的所有功能都是可用的。该项目开发了紧凑的数据表示和可用性驱动的功能，这些功能可以保护隐私。该项目还评估了人们对自己的行为对隐私的影响的期望，以及算法的未来行为，以创造一个简单、透明和可预测的环境，以促进广泛采用。由于社交网络渗透到现代生活中，该项目将通过将可用的隐私技术纳入社交网络结构而产生重大影响。该项目还通过为本科生和研究生提供研究机会，培养研究与教育的结合，同时通过外展活动提高公众对隐私问题的认识。

Social networks provide many benefits, but also give rise to serious concerns regarding privacy. Indeed, since privacy protections are not intrinsically incorporated into the underlying technological framework, user data is still accessible to the social network and is open to misuse. While there have been efforts to incorporate privacy into social networks, existing solutions are not sufficiently lightweight, transparent, and functional, and therefore have achieved only limited adoption. This project develops a privacy-preserving social network (Trusted-Space) where user data are protected from the social network itself, other social network users, and advertisers. The project synthesizes solutions from a technological and sociological perspective to ensure that all of the required functionalities for both users and advertisers to participate effectively in the social network are available. The project develops compact data representations and usability driven functionalities that are privacy-preserving. The project also evaluates people's expectations about the implications of their own actions on their privacy and the future behavior of the algorithms, towards creating a simple, transparent, and predictable environment to facilitate widespread adoption. Since social networks permeate modern life, the project will have significant impact through enabling the incorporation of usable privacy technology into the social network fabric. The project also cultivates the integration of research and education, by providing opportunities for research to undergraduates and graduates, while increasing the awareness of privacy issues among the general public through outreach activities.
