Abstract

Access control is an important aspect of shared virtual environments.Resource access may not only depend on prior authorization, but alsoon context of usage such as distance or position in the scene graphhierarchy. In virtual worlds that allow user-created content, participantsmust be able to define and exchange access rights to controlthe usage of their creations. Using object capabilities, fine-grainedaccess control can be exerted on the object level. We describe our experiencesin the application of the object-capability model for accesscontrol to object-manipulation tasks common to collaborative virtualenvironments. We also report on a prototype implementation of anobject-capability safe virtual environment that allows anonymous,dynamic exchange of access rights between users, scene elements,and autonomous actors.
