The Concept of Personal Data Revisited
Along with the concept of personal data, as opposed to anonymous data, the Regulation introduces a third category, that of pseudonymous data.
Pseudonymous data is information that no longer allows the identification of an individual without additional information and is kept separate from it. In exchange for the lower level of privacy intrusion, the applicable requirements are less stringent. At the moment the standards according to which data is considered as anonymous or pseudonymous are established by the DPAs at a national level. Once the Regulation comes into force, the requirements and the applicable regime will become more uniform and this will provide greater legal certainty.
