摘要
针对手机用户安全问题,提出一种基于手机加速度传感器的手势身份认证方法。采用均值—方差归一化方式对三维手势数据进行归一化处理;采用门限值方法截取手势动作,去除干扰数据;认证算法采用模板匹配的方式,通过设计的均值—动态时间归整(A-DTW)算法对参考模板和测试模板进行比较,判断用户的真实性。仿真结果显示:该算法方便可行,具有较高的识别率。
Aiming at mobile-phone users＇ security issues, a gesture identity authentication method based on acceleration sensor is proposed. 3D gesture data are processed by the mean-variance normalization;and the data of the moving gesture are intercepted by using a threshold value to remove interference data;authentication algorithm adopts template matching method. The authenticity of the user can be determined by the average-dynamic time warping（ A-DTW）algorithm through comparing reference template with test template. The simulation results show that the proposed algorithm is convenient, feasible and has a good recognition rate.
