適用於行動設備的數位權利管理系統

Digital Right Management Suitable for Mobile Equipments

在這個資訊快速傳遞的時代，行動設備與通訊網路也日趨健全，人們可以不再受限於較大型的電腦設備及有線網路，透過行動設備與通訊網路的結合，可以讓更多的人不再因時間、地點與空間的限制，更快速取得所需資訊進行娛樂、商務、學習等各項活動。而在這些活動之中，經由數位權利管理的保護，讓使用者在利用各式的行動設備擷取數位內容時更加安全。本研究主要目的為利用行動設備所使用串流傳輸的特性，簡化已購買過的串流媒體再度播放流程與接續上一次多媒體播放的時間點，且當使用者們在取得串流傳輸的數位內容後，可以隨心所欲使用已購買的數位內容以及如何去鞏固使用者自身的權利，另外，保障數位內容提供者的權益，免除數位內容被惡意的傳播造成利益的損害。透過本系統，行動設備可以更加便捷取得所需資訊，同時也讓數位內容的使用可以更加的安全與有彈性。

In this rapidly information transferred era, the development of mobile devices and communication network has become mature. Individuals are no longer restricted by time, location and space in obtaining online information due to the use of larger personal computer and cable networks. Instead, users are now able to obtain information more quickly and effectively to undertake entertainment, business and learning activities through the consolidation of mobile devices and wireless communication network.? In these behaviors, the transferred digital contexts are protected by the digital rights management, which provides better security to users capturing the digital information with various mobile devices. The purpose of this study is to utilize the characteristics of streaming identity of mobile devices to reduce the time of replaying purchased streaming media and continuing broadcasting previous play for multimedia players. In addition, after users obtain streaming digital contents they could use these purchased digital contents as their desire, and protect the rights of users and content providers in order to avoid the malicious content spreading and the benefit loss.
