Abstract

This paper proposes a new model of access control by analyzing the window and attributes of the object, and based on this, a mechanism that offers a seamless multimedia view without interfering with access control is also suggested. There are two approaches to software architecture on which applications for multimedia distance education environment in situation-aware middleware are based. Those include CACV(Centralized-Abstraction and Centralized-View) and RARV(Replicated-Abstraction and Replicated-View). To win over such dilemma for centralized or replicated architecture, a combined approach, CARV(the Centralized Abstraction and Replicated View) architecture is used to realize the application sharing agent.
