Pressure measurement - blurring of the image

Municipality of The Hague

Algorithm that on the Scheveningen promenade ensures that (after counting and determining group dynamics) the camera clip is blurred.

Goal and impact

This was a pilot that has ended. The aim is efficient enforcement on crowds. The algorithm aims to make people unidentifiable. Even personal data such as height and thickness should not be traceable.

Considerations

It was a first experiment to work with blurred (=anonymised) image clips, in addition to working only with enforcers.

Human intervention

Yes, the enforcer. Camera and algorithm can be stopped at any time. The enforcement organisation can also ignore the signals.

Risk management

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.

Legal basis

Municipal Act. Section 172 Maintenance of public order (camera images) and Section 151C (processing camera images under police direction).

Elaboration on impact assessments

A DPIA has been carried out (DPIA pressure measurement and group dynamics) describing the risks and measures.

Impact assessment

Data Protection Impact Assessment (DPIA)

Operations

Data

Camera footage.

Technical design

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.

External provider

Processing took place by the supplier Natix (Hamburg), with whom a processing agreement was signed.

  • Automatic face comparison

    Netherlands Forensic Institute

    In an expert examination, facial images are compared. The facial image comparison aims to determine whether a person visible in camera images (crime suspect) and the image of a known face (police photo of a suspect) are of the same person or two different people.

  • Camera identification

    Netherlands Forensic Institute

    An investigation by an expert examines whether certain digital images (photos and/or videos) were taken with a certain digital camera and/or mobile phone. To answer this question, the camera identification algorithm is deployed, which identifies the camera.
