Open Mobile -Alliance (OMA) DRM is a mechanism used for protecting distributed content. -Using DRM, the content can be accessed on authenticated devices depending -on the usage rights set by the content owner. OMA DRM addresses the various -technical aspects of this system by providing appropriate specifications for -content formats, protocols, and a rights expression language.

-

Application developers are directly affected by the manner in which content -is distributed, such as whether content can be freely copied between devices -or not. The introduction of OMA DRM technology changes the way content is -distributed and consumed. Understanding and using the OMA DRM standard enables -your applications to gain access to high-quality branded content.

-

Because OMA DRM is an industry-wide standard, no other DRM solution can -provide access to as many mobile users. OMA DRM contains a client component, -providing a mechanism to control not only piracy via the mobile network but -also via local connections, such as Bluetooth, infrared, and MultiMediaCard -(MMC) memory cards. OMA continues to develop DRM standards as a joint effort -among its members.

-

The following OMA DRM versions are supported:

- -

OMA DRM v2.0 and v2.1 offer improved protection and support features, but -due to higher licensing fee it is not as widely used as v1.0.

-

Nokia Mobile Internet Toolkit is an example of a tool -that can be used to create mobile content with OMA DRM protection.
