Implementing OMA DRM Using Web Services: An Approach to Integrate OMA DRM and Web Services on Mobile Units

In this paper an approach for using Web services to facilitate non-proprietary digital rights management for mobile devices is described. The approach is based on the open mobile alliance's (OMA) DRM specification which is an interoperable industry quasi-standard in the mobile world. To be able to use the OMA-specific license delivery protocol in a more flexible and portable manner, employing Web services seems to be the best solution. This article describes a possible design for such a system and a prototypical implementation that has been developed as proof- of-concept. Along the way the challenges to be solved to obtain the designed system are explained and solved.
