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.

Responsible use

Goal and impact

Once it is found out which type of camera the images were taken with, the results of the investigation can be used in a criminal investigation.

Considerations

We do this on behalf of the examining magistrate in criminal cases to investigate and resolve criminal offences.

Human intervention

Humans have to interpret and validate the results of the algorithm.

Risk management

The software is available to LEA organisations.

Operations

Data

At issue is the PRNU pattern, which is a type of noise pattern specific to a particular sensor in a camera.

Technical design

The input consists of an image or multiple images, or video footage from a camera. The noise patterns are extracted. New images are taken with the camera, from which the noise pattern is then also determined. The noise patterns are then compared in a database. To identify the camera, the Photo Reponse Non Uniformity pattern is used with images taken with that camera.

  • Camera surveillance traffic measure (closed)

    Municipality of Haarlemmermeer

    Automatic Number Plate Recognition cameras (ANPR) at four different locations record license plates of passing motor vehicles. The algorithm checks whether an exemption has been granted and determines whether photos are submitted for review in the enforcement system.

  • 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.

  • Sound sensors: Smart sound meter

    Municipality of Amsterdam

    This algorithm has a low impact. The aim of the pilot is to identify incidents in public spaces earlier. Using an algorithm, the sound sensor can figure out the type of sound source.
