随着智能手机和平板电脑等智能设备的迅速普及，用户身份验证变得越来越重要，因为涉及用户隐私的各种数据都在这些设备中处理。目前，在智能设备的情况下，基于密码的身份验证被频繁使用；然而，生物特征身份验证作为一种用户身份验证技术受到了更多的关注。智能设备配备了各种传感器，如摄像头、麦克风和触摸屏，其中许多都可以获得生物特征信息。虽然许多智能设备都具有生物特征认证功能，但为了更安全、更方便地进行用户认证，仍有一些问题需要解决。本文总结了当前智能设备用户认证存在的问题，提出了一种基于上下文感知的用户认证系统来解决这些问题。我们还使用从智能设备获取的生物特征信息对系统的性能进行了评估。评估结果证明了该系统的有效性。关键词：智能设备、用户认证、生物识别、情境感知、环境识别
With the rapid spread of smart devices, such as smartphones and tablet PCs, user authentication is becoming increasingly important because various kinds of data concerning user privacy are processed within them. At present, in the case of smart devices, password-based authentication is frequently used; however, biometric authentication has attracted more attention as a user authentication technology. A smart device is equipped with various sensors, such as cameras, microphones, and touch panels, many of which enable biometric information to be obtained. While the function of biometric authentication is available in many smart devices, there remain some problems to be addressed for more secure and convenient user authentication. In this paper, we summarize the current problems with user authentication on smart devices and propose a novel user authentication system based on the concept of context awareness to resolve these problems. We also present our evaluation of the performance of the system by using biometric information that was acquired from smart devices. The evaluation demonstrates the effectiveness of our system. key words: smart device, user authentication, biometrics, context awareness, environment recognition
