Digital rights management broadly refers to a set of policies, techniques and tools that guide the proper use of digital content. A DRM plays important roles in several processes that are involved in the flow of content. The major functionalities of this DRM system are: packaging of the raw content for easy distribution and tracking, content protection for tamper-proof transmission, delivery of content offline on CDs and DVDs and delivering content on-demand over peer-to-peer networks. Thus a set of standards related to various aspects of DRM are practiced in order to ensure fairness, interoperability and also for the consumer confidence.
