What Mainzelliste can do for you

Mainzelliste is a web-based open source pseudonymization software which was originally designed at Mainz University Medical Center and now is actively developed by the members of Mainzelliste community under the leading of the Federated Information Systems working group from DKFZ, Heidelberg. It allows the generation of the pseudonyms (PID) from the identifying fields (IDAT) even if the identifying data has errors. Mainzelliste methods are accessed through can be accessed through the REST interface, which allows an easy integration within other tools.

Overview of Pseudonymization

Main functionality of Mainzelliste:

  • Pseudonym generation – substitution of identifying personal data with the string not related to the original data

  • Record Linkage – for each patient there is only one pseudonym of a certain type which is generated, even if there are small errors in the identifying data. Near the record linkage based on the raw identifying data, Mainzelliste also allows the privacy preserved record linkage based on the irreversibly transformed identifying fields and the secure multiparty computation where the identifying data never leaves the storage.

  • REST Interface – allows the connection of Mainzelliste to different systems, such as registrys, biobanks, EDC and study management systems.

  • Graphical interface – allows easy use of Mainzelliste functions without showing the complex workflow behind them.

  • Backward compatibility

  • Audit Trail
