Goal and impact

Automated face comparison serves two purposes:

1. Establishing the identity of the identity card applicant to prevent identity fraud; and

2. Keeping the information in the Basic Registration of Persons (BRP) reliable.

A desk clerk does the checking. If the application using the algorithm indicates that the person whose face has been compared is not the person standing at the counter, the counter employee engages a colleague (as a second line) to verify this finding.

These staff apply the 'four-eye principle' when in doubt about the face comparison finding. If they conclude, partly on the basis of their own assessment and observation, that the finding of the face comparator is correct and the identity of the applicant does not match the identity in the photograph, the application for a first registration/resettlement in the BRP or naturalisation will not be processed. This may indicate whether fraud is suspected. If fraud is suspected, 112 is called and the police are called in for further investigation. In this context, the Civil Affairs Department acts in accordance with the model working instruction on identity fraud issued by the WTI (Working Group on Countering Identity Fraud).

Considerations

The deployment of this algorithm helps employees of the civil affairs department determine the identity of the resident at the counter. The facial comparator can determine the biometric features in the face more accurately than the human eye.

Human intervention

The face comparator is a tool, the final assessment is made by a staff member. As mentioned, the 'four-eye principle' is applied if the finding of the facial comparator is negative.

Risk management

Using the facial comparator when registering for the BRP or applying for resettlement or naturalisation eliminates the risk of potential profiling in advance.

The next risk is that the facial 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: Art. 2.67(4) BRP Act

- Admissibility of biometrics: art. 29 UAVG, in the present situation authentication is necessary
