iCabinet: Stand-alone Implementation of a Method for Preventing Illegal Recording of Displayed Content by Adding Invisible Noise Signals

摘要

A previously proposed method for preventing the illegal recording of displayed content by adding invisible noise signals to the recorded content during recording to make it unrecognizable has now been implemented in a stand-alone cabinet. Testing using the prototype stand-alone implementation demonstrated that it can effectively prevent illegal recording of displayed content by completely corrupting the recorded content. This illegal recording prevention method is applicable not only to content displayed on a screen but also to other things that should be protected against illegal recording such as confidential documents in a public office and art objects in a museum.
