A method for detecting playing of unauthorized downloading of digital data files having soundtracks by an Internet enabled machine including the steps of: (a) applying identification signals to the soundtracks at frequencies outside of human audible range; (b) encrypting the digital data files in a format requiring appropriate software to be played by media players; and (c) freely providing the appropriate software for playing the digital data files to generally available media players as an add on configured as a plug in downloadable form from an Internet website, where the appropriate software includes: (i) a cache for caching data identifying digital data files downloaded or played; (ii) data to identify unique components of hardware; (iii) a packetizing arrangement for packetizing the data identifying digital data files downloaded or played; (iv) a transmission arrangement for transmitting packetized transmission as a piggybacked transmission; and, (d) providing a Mimic Server that mimics a Domain Name Server.
