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