How anonymous are you?!

3 May 2022 , 15:00 19:00 CEST

Statistics Netherlands (CBS) has enormous amounts of data at its disposal, from which social networks are also derived. But how anonymous are you in this data? Is it possible for hackers to extract sensitive information from these data sets, by combining them with other data sources?

In the hackathon ‘From Person to Open Data’, you, as a ‘potential attacker’, will search for network relations of a given list of people. If you are able to find the most relations within 4 hours, you receive a prize!

Interested? Sign up for free before April 27th! The link to the registration form is available on Brightspace, or request the registration link via popnet@uva.nl.
Pizza and drinks at the end of the day are included, and during the hackathon, we will provide beverages and snacks.

For whom?
Students. You don’t have to speak Dutch, but it can be advantageous, since the data is about Dutch people. You can sign up as a team of two, but it is also possible to sign up individually. If you want, we will pair you up with another student on the day itself.

This hackathon is organized by the Anonymity in Complex Networks project (ANO-NET), the Methodology department of Statistics Netherlands (CBS), the Population-scale Social Network Analysis (POPNET) project of the University of Amsterdam and Leiden University and the Computational Network Science (CNS) research group of Leiden University.
