Systems and methods that facilitate the management of digital content in a local environment between a limited number of parties. A digital rights management (DRM) agent-server can be created in hardware in which both the agent-server and agent are trusted. A content owner can send digital content along with a rights attachment indicating a scope of the use rights associated with the content. The content can be accessed by the agent and perceived in a presentation component that will only permit the agent to use the content in accordance with the rights granted as to the content. The DRM agent-server can be implemented by an application-specific integrated circuit (ASIC). Further, the DRM agent-server can be implemented on a portable electronic device such as a cellular phone, a personal digital assistant (PDA), or a laptop computer, for example. |
