Preserving Link Privacy in Social Network Based Systems

Speaker: Prateek Mittal, Princeton

Abstract:

We show that it is possible to enable the design of social network based systems, while protecting the privacy of users' social contacts. Our approach is to perturb the social network graph, by removing existing edges and adding fake edges, such that the local community structures in the network are preserved. We characterize utility and privacy of such perturbed graphs.
