    • Anonymous, anonymized or pseudonomized?

      Data can be considered as anonymous or anonymized, only when it is not possible to “single-out” individuals with the data provided and when the applied mechanisms to anonymise are irreversible.

      Anonymous data is not identifiable data from the start, while anonymized data is data initially identifiable but for which a process has been put in place to make it not identifiable anymore (GDRP: art. 4(5)).

      Pseudonymisation means processing research data in such a way that they can no longer be attributed to a specific person without the use of additional information like a coding key. This usually involves replacing identifiers from the data with a pseudonym (GDRP: art. 4(5)).
