In August 2016, Data Protection Commissioner (“DPC”) of Ireland published guidance on the use of data anonymisation and pseudonymisation. Guidance provides recommendations on effective use of anonymisation and pseudonymisation techniques.
Anonymisation and pseudonymisation techniques help organisations to better comply with security requirements of data protection law. General Data Protection Regulation (GDPR) encourages organisations to use pseudonymisation techniques while effectively and irreversibly anonymised data is not “personal data” and the data protection principles do not to such data.
