An enforcement architecture and method for implementing digital rights management are disclosed. Digital content is distributed from a content server to a computing device of a user and received, and an attempt is made to render the digital content by way of a rendering application. The rendering application invokes a Digital Rights Management (DRM) system, and such DRM system determines whether a right to render the digital content in the manner sought exists based on any digital license stored in the computing device and corresponding to the digital content. If the right does not exist, a digital license that provides such right and that corresponds to the digital content is requested from a license server, and the license server issues the digital license to the DRM system. The computing device receives the issued digital license and stores the received digital license thereon.

Enforcement architecture and method for digital rights management

A digital rights management (DRM) system operates on a computing device and requires a black box for performing decryption and encryption functions. To obtain the black box from a black box server, the DRM system requests such black box from such black box server. The black box server in response generates the black box, where such black box is unique and has a public/private key pair. The black box server then delivers the generated black box to the DRM system and the DRM system installs the delivered black box in such DRM system.
