NOBID Identity Matching project
Identity matching (IdM) refers to the process of recognizing and linking a user's identity across different systems or jurisdictions. In a cross-border context, this means identifying a user from country A who has already been registered or authenticated in country B.
Identity matching constitute a fundamental prerequisite for the realization of cross-border access to digital services and is an important priority in the NOBID countries.
Whereas the eIDAS regulation sets down common rules for secure and seamless use of digital identities across Europe, the Nordic and Baltic region strongly recognize the necessity of identity matching solutions to ensure the realization of cross-border services in Europe.
The recognition of identity matching as a key priority to be solved is shared by the Nordic and Baltic ministers for digitalisation and the Nordic Prime Ministers.
To solve identity matching, the NOBID co-operation recently (2025) launched a dedicated sub-project on the matter that involves both digitalisation- and population registry authorities from the region.
The aim of the project´s 1st phase is to develop and test concepts for identity matching between the countries in the region, build upon the common strengths and features, and deliver a technical PoC of an identity matching, self-service, solution that work with both eIDAS 1.0 and eIDAS 2.0.
The PoC is being developed in cooperation with Kantega AS. The 2nd phase of the project will span throughout the autumn of 2025.
Coming soon: Test the IdM PoC yourself
FAQ
A returning individual is someone who has digital user relationships or legal entitlements in one country but resides in another. Typical examples include:
- Pensioners receiving benefits from a former country of employment
- Students with education from abroad
- Workers with rights and obligations across multiple countries
The goal is to ensure that such individuals can be easily and securely identified when they return to use public services across borders — without needing to register again each time.
The project is developing technical software code (software solutions) for digital identity matching. This code can be integrated into national systems, allowing each participating country to adopt the solution as needed.
If the system identifies a match, the individual is immediately recognized and granted access to relevant services.
- If no match is found, the system proceeds to a biometric-based registration process.
- This involves facial recognition and document verification, enabling secure, one-time identity creation that can later be matched.
Two different solutions are being developed and made available for testing:
- Solution A focuses on integration with national population registers and provides a seamless user experience.
- Solution B is based on a modular technical architecture, with strong emphasis on privacy and data protection.
Both solutions aim for certification under the EU’s eIDAS 2.0 regulation, ensuring compliance with future European digital identity standards.
- Simplify cross-border access to public services
- Ensure secure and efficient recognition of individuals with rights and obligations in multiple countries
- Strengthen European cooperation and contribute to a common digital identity framework
