Risk

Life Cycle Stage

Practices

• Use automated scripts that routinely delink identifiers from datasets after data processing is complete, as practiced in some Nordic countries’ privacy frameworks.

• Implement temporary session identifiers in online services that expire after the session ends. Pairwise pseudonymous identifiers should be used wherever possible to prevent correlation of user data across interactions.
