摘要:

用户身份认证是智能终端信息安全和隐私保护的核心问题。基于生物特征的指纹认证方式直接把个人重要的特征信息存储在智能设备上,存在信息泄露隐患。文章基于市场上智能终端内置重力传感器的特点进行研究,使用智能终端的三维加速度计收集用户行为数据,利用用户行为来判断用户身份。为了提高识别精度和识别效率,选取特定的设备姿态作为合法姿态,用户从合法姿态库中选取任意组合,将这个组合作为认证密钥(姿态密钥)。与基于生物特征的认证方式相比,基于用户行为的认证方式不存在个人重要特征泄露的危险,且避免了记忆繁杂的知识型密码。实验证明,该方案的识别精度高。

Abstract:

User authentication is an essential issue to smart terminal information security and privacy protection. Fingerprint authentication based on biometric features directly stores personal important features information on smart devices, which leads the risk of information leakage. Based on the characteristics of the gravity sensor in the smart terminal in the market, this paper uses the 3D accelerometer of the smart terminal to collect the user behavior data and identify the user. In order to improve the accuracy and efficiency of the recognition, the user can select any combination from the legal gesture library and use the combination as the authentication key (gesture key). Compared with the biometric-based authentication method, the authentication method based on user behaviors does not have the risk of revealing important personal characteristics, and avoids complicated knowledge passwords. Experimental results show that the proposed method has high recognition accuracy.

Key words: smart terminal, gravity sensor, identity authentication, gesture key
