DRM
Digital Rights Management, DRM, is a technology that enables secure distribution, promotion, and sale of digital media. Examples of such content include images, wallpapers and screen savers with themes from films, ringtones from musical artists, and branded games. In other words, content providers can control how users may use different types of content in devices, such as mobile phones, smartphones or PDAs. Content providers can also control the use of content in related services, such as MMS.
Sony Ericsson is actively focusing on technology standardization for the DRM concept, and supports the ongoing standardization work and activities of the OMA (Open Mobile Alliance). Sony Ericsson is fully committed to open standard solutions in the mobile environment and is a principal driver of many open standard initiatives. This will ensure the interoperability of mobile terminals in the DRM area and also result in a strong, competitive DRM standard.
Packaging of rights and content
Rights and content can be packaged together and delivered to the device as one DRM package. As an alternative, content can be delivered to the device first, followed by the rights later being pushed to the device, for example via SMS. The kind of service and business model adopted by the content provider determines how the content and rights should be packaged and delivered to the device.
DRM packager
A DRM packager is typically included in the software used by the content provider. It is used to create the DRM package that is delivered to the device, including content and associated rights. In the device, the content of the DRM package is made available to the user according to the rights. For example, if the rights permit the user to play a ringtone ten times, the device will keep track of the number of times the ringtone is played, and notify the user when the ringtone has been used for the tenth time.
How DRM works
The control of the content in digital media is executed by defining usage rights for the content. The usage rights give the content providers flexibility in the way they can publish and sell content. Rights can be defined so that a picture can be used by subscribers only, and rights can be defined so that a ringtone can be played only a limited number of times or for a limited period of time. Rights can also be defined so that the user is not able to forward content to other devices.
Protection properties
Content protection according to the OMA DRM standard gets special properties. Content with forward lock protection has the “Send to” option disabled, which prevents it from further distribution.
Unless the content is encrypted, the user cannot copy DRM content to other devices since the “Send To” option is disabled for pictures, ringtones, etc. that are OMA DRM protected. Content providers may choose to protect some content, but leave some content unprotected.
