Privacy in Social Networks
Objective To protect data available in social networks from attacks that reveal private graph data either by compromising a user or by bribing her (i.e., link privacy attack). Results We have tackled the objective of this project in the following manner: 1) we illustrate how by attacking a small fraction of nodes it is possible to obtain information about a large part of the graph, 2) we explain the difficulties of defending against this type of attack, and 3) we provide strategies to limit privacy leaks. |
