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 Vendors

Below are the some of the DRM vendors

Microsoft
Real Network
Macrovision
IBM
Seclore

Seclore - Information Rights Management
Seclore FileSecure’s IRM connector for IBM FileNet®  empower enterprises with the ability to robustly secure and monitor access to content and information within and outside of IBM FileNet® without any compromise to collaboration and way people work.

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.

Digital Asset Management (DAM)

DAM consists of management tasks related to storage, retrieval and distribution of digital assets. It also refers to the protocol for downloading, renaming, rating, grouping, maintaining and exporting files. The media asset management (MAM) mainly addresses audio, video and animation.
