In this paper, we design and implement the Flexible DRM (Digital Right Management) system based on using subject-mode for flexible multimedia service considering ubiquitous environment. The proposed system is complementary to inflexibility of the users which is a weakness of the traditional contents distribution system. Specifically, because a single using-subject can be flexibly changed under the ubiquitous environment, we attempted to seek the way to support the interactive transaction where both creation and consumption are available. In addition, It supports the super-distribution of the contents under the various environments. Furthermore, we design and apply the license format which can be flexibly used in multimedia devices under the wire or wireless environment.
