Application
Purpose
This is a pilot project. The aim is efficient enforcement on crowds. The algorithm is designed to make people unrecognisable. Even personal data such as height and thickness should not be traceable.
Impact
Citizens face the effect of the algorithm when the enforcer decides to visit.
Proportionality
It is a first experiment to work with blurred (=anonymised) image clips, in addition to working only with enforcers.
Decision making process
Pressure measurement
Legal
Authorized body
The Hague municipality is the processing controller. Processing is carried out by the supplier Natix (Hamburg), with whom a processing agreement has been concluded.
Formal grounds
Municipal Act. Section 172 Maintenance of public order (camera images) and Section 151C (processing camera images under police direction).
Human Rights Impact Assessment (IAMA)

Use-case
Long description
The algorithm recognises people in the images. It then covers them with an overlay such as a black block. The goal is unrecognisability but still seeing enough to determine action.

Usage of base registries
No
Data sources
Camera footage.
Methods and models
Not known to the municipality.
Supervision
Monitoring
The risks of the cameras are tracked. The algorithm itself has no risks.
Human intervention
Yes, the enforcer. Camera and algorithm can be stopped at any time. The enforcement organisation can also ignore the signals.
Risks
A DPIA has been carried out (DPIA pressure measurement and group dynamics) describing the risks and measures. There is no bias, as blurring is determined without preference on types of people. The choice of where to hang the cameras was made together with the enforcers.
Evaluation metrics
Unrecognisability of individuals. In addition, signals should be useful to see if action is needed. Evaluations will be conducted. After the experiment, added value will be weighed against importance.
