About the gPAS

Large research networks, the conduct of clinical epidemiological studies, and also the establishment of registries and cohorts, require data processing that complies with data protection requirements. According to Art. 32 (1a) EU GDPR, the use of pseudonyms helps to ensure an adequate level of data protection for data processing.

We have developed the gPAS® for this purpose. It facilitates the generation and management of pseudonyms. A domain concept enables the structured management of pseudonyms per data source, application context (e.g. collection, release) or location. The characters (alphabet) and algorithms used can be freely defined. The linking of domains enables the creation of hierarchies and the generation of pseudonyms of any level (pseudonymization of pseudonyms). The intuitive user interface provides support for typical tasks - even when processing large amounts of data via list processing. The dashboard provides a quick overview of figures for already generated pseudonyms and configured domains. Users can get started quickly and easily with the user manual provided, which guides them step by step through the functionalities and required configurations.
