基于击键动力学和口令的双因素用户验证

提出基于击键动力学和口令的一种新的身份验证方法，该方法监视用户在输入口令时的用户击键特征的有关数据，通过采用监视键盘输入时一种新的三键持续时间的击键特征表示，用一种表示用户节奏的相对击键速度的距离衡量方式，在正常样本上建立用户模式，然后用新样本与用户模式的距离匹配情况来验证用户身份的合法性。实验表明该方法简单实用，识别效率高。

Two-factor user authentication based on keystroke dynamics and password

A new method for user authentication based on keystroke dynamics and password is proposed.This method adopts a new representation for the duration of tri-char for the user's input feature by monitoring the keyboard inputs,using a new distance measurment standing for the user's relative rhythm.The user's model is established using the normal samples.The distance between a new sample and user's model is judged weather the new sample is belongs to the legality user or not.The experiments show that this method is simple and useful,and has high identification.
