Abstract
A method, device, and system for managing digital usage rights of documents includes a mobile computing device having a digital rights management (DRM) enforcement engine included therein. The mobile computing device may communicate with a server, such as an enterprise digital rights management (EDRM) server, to retrieve a secured document and an associated document usage rights policy. The document and usage rights policy are stored in a secured storage of the mobile computing device. The DRM enforcement engine of the mobile computing device provides access to the requested document while locally enforcing the associated document usage rights policy. In some embodiments, the mobile computing device may act as a proxy for other computing devices communicatively coupled to the mobile computing device and/or act as a local EDRM to such computing devices.
