The multi-lateral security framework for the ubiquitous Internet multimedia

摘要

In this paper, we will present the multi-lateral security model for the ubiquitous Internet Multimedia. Next generation Internet Multimedia are expected to be very flexible digital system build on the global broadband network, which allow us to access any audiovisual contents from anywhere in the world. We call it as ubiquitous Internet Multimedia. In such services, several security criteria, those are not necessary for ordinal audiovisual systems, may become more important. Maintenance of competition between the services, impact to the privacy and suppression of organized crimes are drawing broader interest than before. Since technical discussion often narrowly focused on the unilateral security of contents between the user and system, technological framework, which may model these issues, did not exist. In this paper, firstly we will describe the concept of multilateral security, which technically models above mentioned security criteria. Then we will show simple example how those security issues may technically evaluated.
