ABSTRACT:
A method of preventing unauthorized reproduction of media disposed on a media storage device according to one embodiment is described. The method comprises installing a compliance mechanism on the computer system. The compliance mechanism is communicatively coupled with the computer system when installed thereon. The compliance mechanism is for enforcing compliance with a usage restriction applicable to the media. The method further includes obtaining control of a data input pathway operable on the computer system. The method further includes accessing data, that is disposed on the media storage device, that is associated with the usage restriction. The method further includes preventing the computer system from accessing the media digitally via the data pathway while enabling presentation of the protected media.
