Digital Rights Management is a technology that is used in securing the distribution, promotion and sales of a digital media. It protects digital content through limited usage, like for instance in 3G, where operators and content providers need a method that will allow then to sell content without freely distributing it between devices. DRM is defined by the standards of Open Mobile Alliance (OMA). OMA DRM enables controlled consumption of digital media objects by letting content providers express usage rights like the ability to preview DRM content, to prevention of illegally forwarding downloaded DRM content from to other users, and in enabling super distribution of DRM content. Usage rights are controlled with DRM, these are defined for all types of content. Different rights from different users may be applied on the same content. DRM controls usage rights like the number of times it can be used, the period it can be used and the length of time it can be used. This kind of control enables content providers to create more subscriptions and pay-per-use models and will also stimulate mobile content based services.
