DIGITAL RIGHTS MANAGEMENT IN A DISTRIBUTED NETWORK

摘要

The present invention is implemented within a distributed network operating environment (such as a CDN) in which content providers offload given content for delivery from servers (e.g., CDN edge servers) managed by a service provider (such as a CDN operator). It is assumed that the given content is secured using a digital rights management (DRM) scheme. According to the invention, a distributed set of license server processes are provided to manage the issuance of content licenses. Each of the license server processes is operative to generate licenses by which a given end user client obtains given rights for given content, typically the content served from the machine. A distributed set of license server processes operates in a de-centralized manner and without access to third party business logic (e.g., a payment mechanism) or authentication information associated with end users requesting the given content.
