| Summary: | 碩士 === 國立成功大學 === 工程科學系碩博士班 === 90 === This paper discusses the security problems of Video-on-Demand systems. The encryption algorithms on MPEG-1 and MPEG-2 are based on the standard characteristics and coding styles, but they are not suitable in the MPEG-4 systems. This paper is focused on the encryption/decryption method for the MPEG-4 content characteristics and to provides a new way approach for intellectual property protection. The encryption method develops an efficient way for MPEG-4 content and It requires less computing power than MPEG-1 and MPEG-2 algorithms. It suggests encrypts randomly or purposely selectedan MPEG-4 encryption algorithm based on MPEG-4 object descriptor information. According to the visual-object coding style on MPEG-4, this method approach can bring more is flexibilflexibleity and practicabipracticablelity. In the system architecture design, w. We use incorporated it with the smart cards technology for the robustness of the system security and authentication.
