With the growing need for multimedia data management, security requirements are becoming very crucial. Composing multimedia documents involves bringing together media objects that exist in various formats. These objects may reside in a distributed environment and belong to different security domains. We propose a time-augmented colored Petri net model for multimedia document composition that allows the specification of multilevel security. The model also allows handling of multiple security policies and hierarchical and path based protection schemes
