社交媒体和用户隐私

Social Media and User Privacy

Ghazaleh Beigi

摘要:

在线用户产生了大量的数据。为了更好地服务用户,需要在研究人员、广告商和应用程序开发人员之间共享用户相关数据。公布这些数据将引发对用户隐私的更多担忧。为了鼓励数据共享并减轻用户隐私问题,已经开发了许多匿名化和去匿名化算法来帮助保护用户的隐私。本文回顾了我的博士研究在线用户的隐私,特别是在社交媒体。特别是,我提出了一种新的专门针对社交媒体数据的对抗攻击。我还提供了一种原则性的方法来评估匿名化社交媒体数据的不同方面的有效性。我的工作揭示了社交媒体数据中新的隐私风险,这是由于用户生成数据的固有异质性。

英文摘要:

Online users generate tremendous amounts of data. To better serve users, it is required to share the user-related data among researchers, advertisers and application developers. Publishing such data would raise more concerns on user privacy. To encourage data sharing and mitigate user privacy concerns, a number of anonymization and de-anonymization algorithms have been developed to help protect privacy of users. This paper reviews my doctoral research on online users privacy specifically in social media. In particular, I propose a new adversarial attack specialized for social media data. I further provide a principled way to assess effectiveness of anonymizing different aspects of social media data. My work sheds light on new privacy risks in social media data due to innate heterogeneity of user-generated data.
