Abstract—Access control in 3-D virtual reality systems is a wide and still growing topic. A good access control model is a premise for data security, and makes the whole system play its functions reliably. We compare access control techniques in 3D system OpenSim with that of other virtual reality systems. By using a general extended scheme, we analyze the model and the rule of access control in OpenSim. In this scheme, we provide a method of expanding network services for special proposes. Meanwhile, it verifies the feasibility of developing OpenSim’s services on the basis of data security.

Keywords-Access Control; Capability; Virtual Reality; OpenSim.
