Anonymisation during active research

During the active phase of a project, privacy protection focuses on reducing direct disclosure risk while maintaining analytical utility.

Common practices include:

• Using pseudonymised working data for team access.
• Storing identifier keys separately with restricted permissions.
• Limiting access to identifiable data to essential personnel.
• Avoiding unnecessary duplication of sensitive files.
• Applying secure storage and transfer procedures.

Maintaining clear separation between identifiable, pseudonymised and analysis-ready data supports accountability and reduces accidental disclosure.
