A method and apparatus for digital- rights management is provided herein. Various forms of authorization are allowed (509, 511), with each form of authorization being dependent upon an action taken on the digital content. In particular, when server-based authorization is unavailable (510), less-risky operations are allowed by performing an internal authorization scheme (509). Thus, higher security offered by a server-based DRM (505) is required for risky actions, yet non-risky actions on the digital content may still be taken when the server is unavailable (513).
