Digital Rights Management (DRM)

DRM is a method of controlling access to copyrighted material in available digital format. In other words, DRM is a shield around the digital content like videos and music to stop privacy. It is a digital management of rights.

In order to design and implement DRM systems, the following two architectures to be considered:

1). Functional Architecture

This covers the high-level modules of DRM system that together provide an end-to-end management of rights.

The DRM system can be modeled in three areas:

a). Intellectual Property (IP) Asset Creation and Capture This module manage the creation of content so it can be easily traded and includes asserting rights when content is first created.

b). IP Asset Management

To manage and enable the trade of content.

c). IP Asset Usage

To manage the usage of content once it has been traded.

These models needs to be complemented by the functional architecture that provides the framework for the modules to implement DRM functionality.

 2). Information Architecture

This covers the modeling of entities within the DRM system as well as their relationships.

DRM from IBM

IBM has developed two solutions to enforce DRM at low level:

a). DRM-JVM

In this solution digital rights management has been enforced at Java virtual machine(JVM) level. DRM-JVM does not affect the non DRM solutions.

b). WebGuard

This solution enforces copyrights at the browser level.
