This assignment is part of a project that studies the feasibility of wearable technology that can prevent unwanted photographing or filming. The overall goal is to develop wearables, e.g. glasses, a necklace, or a hat, that can detect that cameras are pointed towards to the wearer and that can prevent that the wearer is being photographed or filmed without consent. The feasibility study is split into three parts, each corresponding to an assignment:

  1. Automatic detection of photographing or filming.
  2. Inhibition of photo and film cameras.
  3. Design of the wearable and ethical aspects.


The goal of this assignment is to study the possibilities to inhibit a photo of film camera that is pointed at a target, from the perspective of the target, i.e. to prevent the camera to photograph or film the target. Possible methods include:

  1. Disturbing the autofocus or the illumination control of the camera.
  2. Disturbing the imaging process by directing (pulsed) light into the lens. Preliminary investigations showed that attempts to saturate the sensor with NIR light will fail because all modern cameras are equipped with a NIR blocking filter.
  3. A combination of 1 and 2.

In the assignment an inventory of possible methods should be made. Attention should be paid to the risks of eye or camera damage. The most promising options should be studied in further detail by means of simulation and or prototyping and be evaluated in terms of:

  1. probabilities of successful inhibition, and
  2. computational complexity.
