The upcoming application of the EU General Data Protection Regulation (GDPR) is an attempt to harmonize the data protection and privacy regulations across member states in the European Union.
However, there is room for deviance in ongoing national law enforcement. Probably article 87 concerning processing of the national identification number and article 88 dealing with processing in the context of employment is where we will see national peculiarities.
National identification numbers are today used in different ways across the member states. In The Nordics, the use of an all-purpose identification number that covers identification of citizens from cradle to grave in public (tax, health, social security, election and even transit) as well as private (financial, employment, telco …) registrations have been practiced for many years, where more or less unlinked single purpose (tax, social security, health, election …) identification numbers are the norm most places else.
How you treat the employment force and the derived ways of registering them is also a field of major differences within the Union, and we should therefore expect to be observant of national specialties when it comes to mastering the human resource part of the data domains affected by GDPR.
Do you see other fields where GDPR will become national within the Union?
