Abstract:

In a method for controlling execution of a digital copy of an original file, a radio frequency identification (RFID) tag read operation is performed using an RFID tag reader. A determination is then made as to whether the physical storage medium is present or absent based on the RFID tag read operation. The digital copy of the original media file is executed when the physical storage medium is determined to be present and execution of the digital copy of the original media file is disabled when the physical storage medium is determined to be absent.
