ENISA releases report on pseudonymization
The European Union Agency for Cybersecurity (ENISA) released a new report on “Pseudonymisation Techniques and Best Practices”, which explores the basic notions of pseudonymisation, as well as technical solutions that can support implementation in practice. The report discusses the parameters that may influence the choice of pseudonymisation techniques in practice, such as data protection, utility, scalability and recovery. It also builds on specific use cases for the pseudonymisation of certain types of identifiers (such as IP address). Among the outcomes of this report is that there is no single easy solution to pseudonymisation that works for all approaches in all possible scenarios.
