Companies involved in mobile content services such as ring tones, wallpapers, or games will be interested in learning more about Digital Rights Management (DRM) and reliable download technologies. These technologies enhance mobile applications and services with better content, new business models, and reliable delivery of assets. Consumers benefit by recieving more dependable experiences with more interesting content services.

The wide adoption of Open Mobile Alliance (OMA) DRM and OMA Download is fast leading to a critical mass of interoperable devices from many vendors. This scenario is necessary to enable, for example, the business case for superdistribution. The open nature of these standards also enables fast integration of these technologies to existing download server platforms from many vendors.

DRM enables owners and sellers of digital content to manage how their content can be sold and used, and supports the development of commercial content services over the Internet and mobile networks. The OMA created two DRM standards to enable interoperable deployment of services that distribute DRM-protected content.

OMA DRM 1.0 was designed for distribution of digital content in mobile networks. Content owners and service providers can use tools available through Forum Nokia to protect their content using OMA DRM 1.0, define usage rights for the content, and distribute the protected content to mobile devices.

The OMA DRM 2.0 specification adds increased security to support distribution of higher-value content, and increased flexibility to support mobile and nonmobile content services. The high security level is based on a Public Key Infrastructure (PKI), backed by a trust model designed to satisfy commercial music and video providers. The specification also supports more flexible business models, including streaming and other packetized media, in addition to licences for groups of content and groups of devices.

Why should I care?

Full OMA DRM 1.0 (that is, forward-lock, combined delivery, and separate delivery) is supported from Series 40 2nd Edition onwards. In the S60 platform, combined delivery and separate delivery were introduced as optional features in S60 2nd Edition, Feature Pack 2. Newer Nokia devices, such as devices based on S60 3rd Edition, support full OMA DRM 1.0, with one exception: the Nokia Eseries devices, which support only forward-lock.

From Series 40 3rd Edition and S60 3rd Edition onwards, some devices may also support DRM 2.0.

What tools can I use?

Nokia Mobile Internet Toolkit (NMIT) 4.1.

NMIT is a content authoring tool that supports the creation of mobile Internet content like XHTML, WAP, and MMS (including SMIL transitions and timeline). Content can be previewed on supported SDKs. DRM protection can be applied to such content.
