Hackathon about anonymity in data was a great success

How anonymous is an individual in a social network dataset? That was the main subject of the hackathon organized by POPNET and Statistics Netherlands (CBS) on May 3 at Leiden University. By looking at openly available data on the internet, students had to derive the social network of several volunteers. The results give insight into what network data can be derived from public data, and therefore to what extent people in networks are really anonymous.
