Abstract
Various embodiments include an apparatus, system, and method to control the distribution and usage of copyrighted digital content. The processing of a data file received over a communications network such as the Internet occurs both in a host digital appliance, such as a personal computer, notebook computer, audio player, video player, and the like, and in a very small digital rights management (DRM) module that is removably connected with the host. The processing makes it extremely difficult for the content of the data file to be obtained by an unauthorized person and/or utilized with an unauthorized DRM module.
