碩士 === 大同大學 === 資訊工程學系(所) === 100 === In recent years, many organization internal systems use and develop the field of mobile peer-to-peer network, but most of these systems that support point to point on a mobile device are lack of security control mechanisms, and digital rights management (DRM) technology can be used to resolve this kind of problems. Nowadays, wireless transmission of mobile devices could be easily thieved by the interested parties, therefore, this thesis proposes a mobile peer-to-peer architecture which possesses file-sharing and control mechanisms, and applies in two kinds of scenarios. The first scenario is to allow authorized users can be assured of using a mobile device to transmit and browse in-house documents. The mobile devices can be used to manage the document via the DRM agent in the system, and the rights description documents embedded in the SIM Card provides the mechanism more security. Besides, the thesis also utilizes the cloud storage mechanism to effectively control the documents access between the various groups. The second scenario is used to apply the architecture for the personal file sharing, allowing individual users to issue the rights of their own files to solve the problem that files only cab be stored into the fixed server. In addition, the mobile users may replace the mobile device because of the lack of hardware; results in the purchased rights cannot be used on the new mobile device. In some rights transfer methods utilize the users must to be verified by the manager and then re-download the license, but the rights transfer mechanism the thesis proposed only needs to verify the identity to the manager and then it will transfer the rest of the rights that does not need to re-download the license from the manager to raise the additional burden of the manager.
