Abstract

XML [15] has become a standard format for information that moves within the World Wide Web. Previous work in securing XML documents concentrated mainly on textual documents. Those proposals are ineffective in the context of multimedia, which mostly comprises of some sensible combination of images, text, audio, and video. As multimedia constitutes a significant component of the traffic within the Internet, it requires to be secured. We propose an access control model and an encryption mechanism that enforces access control and maintains integrity of multimedia by using the Synchronized Multimedia Integration Language (SMIL)[1], thereby preventing illegal or malicious unauthorized access or modifications to the media documents in transition. We show its utility in safeguarding pay-per-view movies and multi-level secure coalitions observing unfolding scenarios.
