National register
Core system for secure storage and management of citizens’ personal and biometric data.
National citizen register
The National Citizen Register (NatReg) is a central repository of demographic and biometric data for a country’s entire population. As the core of the eGovernment infrastructure, NatReg manages both textual demographic information (such as name, surname, and date of birth) and highly sensitive biometric data (including facial images, fingerprints, and iris scans).
Citizen data within NatReg is continuously updated based on key life events – such as births, changes in marital status, or changes of residence – making it a reliable source of authoritative master data for all government agencies.
NatReg platform

NatReg ensures the secure handling of sensitive data through strict access controls and trusted system-to-system exchange, while maintaining a comprehensive audit trail that guarantees traceability, oversight, and accountability.
Platform Use Case

- Secure citizen data storage
- Biometric data acquisition
- Scanning and sorting of paper documents
- Data categorization and management
- Controlled data sharing with other government institutions
- Data analysis, search, and management
- Generation of statistical reports
- Access rights control and monitoring of system activity
- Geographically centralized or distributed system architecture
NatReg strictly controls which system functionalities and which type of data are accessed by both operators and external systems.The systems keeps a cryptographically protected journal of all data changes and actions, which guarantees not only data privacy, but also the ability to track the entire history of data changes of a particular person.
In order to achieve a high level of data protection, NatReg is usually established in combination with our Cryptographically Protected Audit Log (CPAL) subsystem which links data groups and then signs them digitally using cryptographic keys stored on the Hardware Security module (HSM) device. This is how the system data is protected from all sorts of internal threats (including malicious system administrator threats).

Majority of eGovernment systems use some sort of Government Service Bus for exchanging data among various government institutions. Since the protection of government data is of the highest priority, NatReg systems is recommended to be established together with the Crypto Proxy subsystem for secure system authentication on the Government Service Bus and reliable data exchange.
What is achieved in this way is the highest security level regarding data exchange between national registers and other systems which have access to the state main of data. Crypto Proxy guarantees that only qualified institutions may access the state data main and that the exchanged data is visible only to the intended institutions.

NatReg and IDStar are two cornerstones on which the entire electronic identity and citizen data management infrastructure is based. Together they trace secure state processes and form a reliable digital database for online authentication and physical identification of citizens, securing the data and creating the basis for a fully digitalized government administration.
