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，但也引发了人们对隐私的严重担忧。事实上，由于隐私保护没有本质上纳入基础技术框架，用户数据仍然可以被社交网络访问，并容易被滥用。虽然已经努力将隐私纳入社交网络，但现有的解决方案还不够轻量级、透明度和功能性，因此只获得了有限的采用。这个项目开发了一个保护隐私的社交网络(Trusted-Space)，其中用户数据受到保护，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可用。该项目开发紧凑的数据表示和可用性驱动的隐私保护功能。该项目还评估了人们对他们自己的行动对他们的隐私和算法未来行为的影响的期望，以创建一个简单、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，该项目将通过将有用的隐私技术整合到社交网络结构中而产生重大影响。该项目还通过向本科生和研究生提供研究机会，同时通过外联活动提高公众对隐私问题的认识，促进研究与教育的融合。

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.
