针对环绕智能中无需用户参与自动完成身份认证的问题,结合蓝牙ad hoc网和以太网的优点组建了用户身份感知网络,构造了能唯一标识用户身份的蓝牙徽章,实现了一种无需用户配合的身份认证系统.试验结果表明,系统能自动感知用户身份并具有良好的抗干扰能力,为构造环绕智能系统提供了基础.
According to the requirement of automatic sensing user's identity for ambient intelligence, a bluetooth-based identity sensor-net, which combines advantages of bluetooth ad hoc network with ethernet is proposed. A bluetooth badge of user's identification is introduced in detail, so as to build an authentication system without any user's cooperation. It is demonstrated by experiment that the bluetooth-based identity sensor-net can automatically sense the user's identity, and has the advantage of robustness. And it has provided the basis to build an ambient intelligence system.
