Automated document check and face comparator.

Municipality of 's-Hertogenbosch

Automated document check and face comparator when registering in the Basic Registry of Persons (BRP) and applying for identity documents for persons over 18 years old. This Algorithm helps the registrant prevent "look-alike fraud". Sourced from the Rijksdienst voor Identiteitsgegevens (RvIG).

Goal and impact

The automated document check and face comparator serve three purposes, namely: 1. Establishing the identity of the person applying for an identity document to prevent identity fraud; 2. Establishing the authenticity of the source documents supplied from the country of origin to prevent forgery; 3. Keeping the information in the Basic Registration of Persons (BRP) reliable.

If the applications using the algorithm indicate that the person whose identity document and face have been scanned is not the person standing at the counter, the Public Services counter clerk engages a colleague to verify this finding. A number of applications are handled by foreign specialists. These specialists also apply the 'four-eye principle' when in doubt about the document and/or face scan finding. If they come to the conclusion that the finding of the document check and/or face comparator is correct and the identity of the applicant does not match the identity on the source documents and/or photograph, the application for registration in the BRP or the application for an identity document is rejected. This rejection may indicate whether fraud is suspected. In that case, Police and/or Marechausse are called in for further investigation.

Considerations

The deployment of this algorithm helps employees of the Public Service Department determine the identity of citizens at the counter. Documents contain a number of authenticity features that the document scanner can determine more accurately than the human eye. This also applies to checking biometric features in the face.

Human intervention

Yes. There is no distinction in the application of the document scanner and face comparator. Both instruments are used for every citizen who comes to register as a resident of the municipality of 's-Hertogenbosch and/or applies for identity documents. Furthermore, the 'four-eye principle' is applied if the finding of the document check or face comparator is negative. Finally, when identity documents are issued, a final check is carried out by a desk clerk.

Risk management

By always deploying the applications when registering for the BRP or when applying for identity documents, the risk of possible profiling is excluded in advance. The next risk is that the automated document check or face comparator leads to an automated decision. This risk is overcome because the finding is always tested by an employee. In case of doubt by at least 2 employees.

Legal basis

Legal obligation to establish proper identity: BRP Act Art. 2.67 4th paragraph, BRP Decree Art.35 Admissibility of biometrics: UAVG Art. 29, in the present situation authentication is necessary.
