Introduction

Researchers should consider appropriate measures to protect the privacy of research respondents. One way to do so is by anonymising or pseudonymising research data that includes personal data.

Below you will find more information on what these processes imply, techniques and tools that can be used for quantitative and qualitative data, the different phases of research, as well as the definitions of relevant terms.

Make a plan

You should make a plan as early as possible, laying down which anonymisation and pseudonymisation techniques you will apply in which research phase. This will help you set up your study in a privacy by design fashion and will save time and costs in the long run.
