Project PrivDA

From June 1st, 2018, to May 31st, 2021, I led the research project PrivDA – Privacy-preserving Publication of Dynamic Social Network Data in the Presence of Active Adversaries, funded by Luxembourg's Fonds National de la Recherche, under the CORE program, junior track, Ref. No. C17/IS/11685812.

PrivDA aimed to provide methods for safely releasing privacy-sensitive structural information from dynamic social networks, accounting for, and counteracting, the presence of active adversaries, i.e. adversaries with the capability of enrolling fake users (also known as sybils) to interact with the network during the publication process. The project focused on studying how the dynamic nature of the networks and the release process can be exploited by active adversaries, as well as defining novel ways to quantify privacy in the dynamic scenario and proposing new models and algorithms to enable social network owners to safely release information in two manners: (1) periodically publishing anonymised versions of the underlying dynamic social graph, and (2) answering structural queries about the network.

Additional details on this project can be found here.
