碩士 === 國立臺灣科技大學 === 電機工程系 === 95 === We have implemented the digital right management (DRM) system for real-time image streaming. It comprises one license server to identify user’s legal access rights and one media server to provide real-time scalable bitstream to the user IPMP terminal according to the authenticated access rule, i.e., resolution, frame rate or quality. In the handshaking process between a client and the server, the user’s password and user’s certificate will be encrypted with AES algorithm and send by TCP protocol. The media server adopts the JPEG2000 image coder to provide scalable image bitstream, for either off-line media files or on-line media sources, and uses the block-shuffling algorithm to perform content encryption. In our example, it capture images from a real-time webcam and perform encoding and encryption. Finally, it sends the protected image to client by UDP protocol. In words, we have implemented one DRM system that integrates IPMP terminal, license server and media server to provide real-time image streaming service.
