Scientists at the Georgia Institute of Technology in the U.S. have developed a prototype device designed to disable digital cameras. The commercial version of this device will be used to combat unauthorized photography with digital equipment.
The ability to take photos and record videos has expanded significantly. As a result, photographers equipped with modern digital cameras are increasingly infringing on privacy, while “pirates” record films in theaters, and industrial spies steal technological secrets by photographing documents using mobile phone scanners. So, how can we respond?
Recently, scientists at the Georgia Institute of Technology have created a prototype device that effectively disables digital cameras. The commercial version of this device will be employed to prevent unauthorized photography. One of the main objectives is to control video recording devices in movie theaters, as well as to combat espionage in government facilities. Experts assert that copyright theft is the primary reason for the creation of this device.
Previously, theater staff would chase after individuals recording films illegally. They employed infrared beams to scan the audience and identify areas where video cameras were reflecting: the “retina” in a camera reflects differently than eyeglasses or any shiny object. To catch these unauthorized recorders, a bounty was even established in the U.S., as annual losses from the distribution of copies of films are estimated at 3 billion USD.
The “anti-digital” device operates on a similar principle. It detects digital cameras based on reflection: if the shape and other characteristics of the reflective object resemble a standard “retina,” a thin beam of light will be directed towards it to control the recording.
