Privacy is one of the friction points that emerges when communications get mediated in Online Social Networks (OSNs). Different communities of computer science researchers have framed the ‘OSN privacy problem’ as one of surveillance, institutional or social privacy. In tackling these problems they have also treated them as if they were independent. We argue that the different privacy problems are entangled and that research on privacy in OSNs would benefit from a more holistic approach. In this talk, we first provide an introduction to the surveillance and social privacy perspectives emphasizing the narratives that inform them, as well as their assumptions, goals and methods. We then juxtapose the differences between these two approaches in order to understand their complementarity, and to identify potential integration challenges as well as research questions that so far have been left unanswered.


Claudia Diaz is currently an assistant professor in Privacy Technologies at COSIC (Computer Security and Industrial Cryptography), in the Department of Electrical Engineering of the KU Leuven. She received her Master degree in Telecommunications Engineering at the University of Vigo (Spain), and her Ph.D. in engineering at the KU Leuven (Belgium). Her research is broadly focused on the topic of Privacy Enhancing Technologies, where she has published on topics including anonymous communications, anonymity metrics, steganographic file systems, location privacy, privacy in social networks, traffic analysis, and privacy by design.
