Method and system for selectively controlling access to protected media on a media storage device
DCFirst Claim
1. A method for selectively controlling access to media disposed on a media storage device, said method comprising:
- installing a compliance mechanism on a computer system, said compliance mechanism communicatively coupled with said computer system when installed thereon, said compliance mechanism for enforcing compliance with a usage restriction applicable to said media;
obtaining control of a data bus data pathway operable on said computer system, the data bus accessible by a processor of the computer system;
obtaining control of a sound card data pathway operable on said computer system;
accessing data disposed on said media storage device to determine said usage restriction; and
selectively preventing said computer system from digitally accessing said media via said data bus data pathway while enabling presentation of the media via said sound card data pathway, said sound card data pathway inaccessible to the processor of the computer system.

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.
