Abstract:
A system, business methodology and apparatus for facilitating controlled dissemination of digital works is disclosed. An audio and video organizer, entertainment, and communication unit that plays back audio and video media content received from a central storage server. The unit relies on a smartcard, which has a personalized key that unlocks encrypted content. Using the unit, a user can purchase music or other types of media using a appropriate ordering method. The central storage server then transmits a double-encrypted, compressed audio file to the unit, where it is decrypted based on the smartcard key, and available for listening.
