Personal Tech Pipeline New Gadget Blocks Digital Video Recording: "Scientists at Georgia Tech have developed a device that could block digital recording in movie theaters and elsewhere.
The prototype, announced this week, shows promise for stopping piracy and espionage. It can locate digital cameras' image sensors, which reflect light directly back to its source rather than scattering it. It sends a thin beam of white light back to the camera, blinding the camera and destroying the recording.
The device does not work with traditional cameras, which lack the telltale sensors, or the SLR cameras.
Associate Professor Gregory Abowd of the Georgia Tech College of Computing and members of his research team are trying to refine the system so it can discriminate between cameras and other objects. The system currently uses cameras and computer software to search for reflected light. Eventually, it could rely on lasers and transistors instead.
In addition to preventing film piracy, which the Motion Picture Association of America claims cost $6.1 billion in 2005, the devices could block recordings of government buildings or corporate assets. "
