About the gPAS

The use of pseudonyms is a privacy-enhancing technique supporting privacy-by-design and ensuring non-attribution. Pseudonymisation allows storing directly person identifying data separately and securely from medical data and supports the data controller to meet the GDPR’s data security requirements (Art. 32 lit. 1 EU GDPR).

To facilitate the generation and administration of appropriate pseudonyms the Institute for Community Medicine of the University Medicine Greifswald (UMG) developed the web-service-based gPAS.

The use of pseudonymization domains, the specification of individual alphabets and generator algorithms allow for the free generation of different pseudonyms per data source, application context or study site.
