Experience shows that permanent ownership, portability and sharing
(within certain limits) of protected digital content are important
features to end-users. In order to satisfy these customer
requirements, service and content providers should have the
possibility to provide their customers with the quoted features if
they wish to do so. The scope of this work item is to identify
requirements and develop additional technologies to enable the use of
secure removable media with OMA DRM compliant devices. To enable the
OMA DRM based secure removable media, technologies such as
device-to-device authentication, revocation status checking before
engaging in the transfer of DRM protected content, etc. may be
required. New requirement document also will be developed.
