In this paper, a secure multimedia browsing scheme is proposed, which is constructed based on perceptual multimedia encryption and secure key distribution. In this scheme, multimedia data are encrypted perceptually under the control of user key and quality factor. This encryption process combining with Advanced Video Coding (AVC) is of low cost, and keeps file format unchanged. The key distribution scheme deals with user input, authenticates users, and controls the secure multimedia sharing process. Thus, only the users who have registered can obtain multimedia data. And they can be classified into several types according to their payment. The analyses and experimental results show that it is suitable for secure multimedia applications such as Video-on-Demand (VOD) system, Audio-on-Demand (AOD) system, pay-TV, videoconferencing systems, wireless or mobile multimedia, and so on.
