Digital rights management (DRM) is used mostly in digital content such as software, movies or music.The most widespread are the DRMS “fair play” by Apple “Windows Media DRM” by Microsoft and the Open Mobile Alliance OMA DRM. These allow accurate setting of permissions and can be used for various audio and video files. Market leader Apple uses FairPlay from the iTunes Store, Napster and other online music stores primarily use the DRM system from Microsoft.
The OMA DRM is used in almost every mobile phone ring tone, pictures, but also for mobile music and TV broadcasts (mobile TV), for example, Vodafone or T-Mobile.
