EUPID was developed by the Austrian Institute of Technology and is designed to facilitate secondary use of datasets in biomedical research and healthcare by addressing the following major requirements:
- prevent duplicate registration of patients
- avoid creating a transparent universal patient ID but
- provide distinct pseudonyms for patients in different contexts
- preserve the possibility for re-identification by a trusted third party
- keep a protected link between the different pseudonyms in the background, which supports creating merged datasets for secondary use
