Basics of Data Anonymisation

In this 1-hour course, we will cover the concepts of anonymisation and pseudo-anonymisation of data from individuals, and why these concepts are important from a legal, ethical, and security perspective.
Basics of Data Anonymisation


Personal data anonymisation and pseudo-anonymisation.

The aim of this course is to get familiar with the existing techniques and tools that allow personal data anonymisation or pseudo-anonymisation, with cases from research questionnaires, registry data, biometric or biomedical data, and geolocation data. I will also present some solutions for preserving the privacy of the data subjects while working with data that cannot be anonymised (secure computing, privacy-preserving machine learning, federated analysis, privacy-preserving data synthesis). Finally, we will also consider the ethical and legal risks associated with data pseudo-anonymisation.
This seminar is an updated version of Slides at: Personal data (pseudo-)anonymization (
