Experiencing Digital Rights Management in Mobile Environments

Content consumption in mobile devices is no longer limited to ringtones, games or images. The increasing capabilities of new mobile devices include now music and video clips. The content sent to the mobile device and even content created from devices has an increasing value. The application of security mechanisms and the introduction of Digital Rights Management (DRM) can give companies and final users a new way of interchanging content. Nevertheless, it is not easy to provide applications that work on different mobile devices. The specific features of these devices (manufacturers, operating systems, programming environments, capabilities, etc.) make difficult to implement innovative applications for them, especially those related to DRM, which usually involve several security aspects. Different approaches have been taken to overcome these problems, which are presented here.
