Statewatch published an interesting map of EU agencies and interoperable databases and a few international dabases. Their introduction:

This map provides a visual representation of, and information on, the data architecture in the European Union’s “area of freedom, security and justice”. It shows the EU’s large-scale databases, networked information systems (those that are part of the ‘Prüm’ network), EU agencies, national authorities and international organisations (namely Interpol) that have a role in that architecture. It is intended to facilitate understanding and further investigation into that architecture and the agencies and activities associated with it.

The map includes:

• interoperability infrastructure, like the Biometric Matching Service (BMS);
• centralised EU databases like the Central Repository for Reporting and Statistics (CRRS), Common Identity Repository (CIR), European Travel Authorisation and Information System (ETIAS), Eurodac and Entry/Exit System (EES);
• EU agencies like eu-LISA, Europol, Eurojust, Frontex and EPPO;
• the Prüm II infrastructure with the European Police Records Index System (EPRIS) and the Prüm II Router;
• national databases with fingerprints, DNA, facial images, police records and vehicle registration;
• national agencies, like the customs agencies;
• Interpol and its databases, Travel Documents Associated With Notices (TDAWN) and Stolen and Lost Travel Documents (SLTD).

It shows that the EU is developing into a digital superpower.

However, it is unfortunate that the CESOP database is not included. Furthermore, it would be good if the databases and data sharing in the context of anti-money laundering and terrorist financing were added.
