Abstract:
1. A system for preventing unauthorized duplication of audio files, the system comprising: a host audio system standing alone or operationally connected to a network of audio systems, wherein the host audio system stores user-desired audio files or is dimensioned and configured to request user-desired audio files disposed in an audio file storage zone operationally connected to the network; an audio file storage zone operationally connected to the host audio system or the network of audio systems and on which is stored the user-desired audio files, wherein the audio file storage zone is dimensioned and configured to duplicate the user-desired audio files upon receipt of a permissible request to duplicate from the host audio system; a processor and a controller operationally connected to each other, and operationally interposed between and connected to the host audio system and the audio file storage zone, and an instruction zone operationally connected to the processor; a first switch operationally disposed between the controller and the audio file storage zone and between the controller and a first zone, wherein the first switch is configured to toggle between a first position wherein the controller is operationally connected to the audio file storage zone and not operationally connected to the first no-information zone, and a second position wherein the controller is operationally connected to the first no-information zone and not operationally connected to the audio file storage zone, wherein the first switch is operationally connected to the controller which is configured to toggle the first switch between the first and second positions; a second switch operationally disposed between the controller and the audio file storage zone and between the controller and a second no-information zone, wherein the second switch is configured to toggle between a first position wherein the controller is operationally connected to the audio file storage zone and not operationally connected to the second no-information zone, and a second position wherein the controller is operationally connected to a second no-information zone and not operationally connected to the audio file storage zone, wherein the second switch is operationally connected to the controller which is configured to toggle the second switch between the first and second positions; wherein the system is configured so that:
