OMA DRM is a Digital Rights Management (DRM) system invented by the Open Mobile Alliance, whose members represent mobile phone manufacturers (e.g. Nokia, LG, Motorola, Samsung, Sony-Ericsson, BenQ-Siemens), mobile system manufacturers (e.g. Ericsson, Siemens, Openwave), mobile phone network operators (e.g. Vodafone, O2, Cingular, Deutsche Telekom, Orange), and information technology companies (e.g. Microsoft, IBM, Sun). DRM provides a way for content creators to set enforced limits on the use and duplication of their content by customers. The system is implemented on many recent phones. To date, two versions of OMA DRM have been released: OMA DRM 1.0 and OMA DRM 2.0.
In order to ensure that all manufacturers' implementations of OMA DRM can work with each other, the Open Mobile Alliance provides specifications and test tools for OMA DRM.
The OMA DRM group is chaired by Sergey Seleznev (Samsung Electronics).
