Abstract:
The camera has become available independently or embedded in devices, it is now possible to capture still and moving images anywhere, raising a legitimate concern for many organizations and individuals. Although legal and social boundaries can curb the capture of sensitive information, it sometimes is neither practical nor desirable to depend on camera holder's honesty to legal and social boundaries.
This thesis present the design and test of the concept of implementation of a camera jamming device that prevents the recording of still and moving images without requiring any cooperation on the part of the capturing device or its operator. This solution involves a tracking system that uses computer vision for locating any number of retro-reflective CCD or CMOS camera sensors in a protected area. A pulsing light is then directed at the lens, distorting any imagery the camera records. Although the directed light interferes with the camera's operation, it can be designed to minimally impact the sight of other humans in the environment.
