摘要
击键韵律是以人的行为特征为基础的身份认证技术。对PR-RP算法模型进行分析,参照PR-RP模型中四个关键的数据集,重新构建P-P时延数据集和R-R时延数据集,并且只选取密码的击键特征进行处理。然后建立特征模板,并在此模型的基础上对特征模板进行实时更新,保证特征模板中数据为用户的最新特征,来达到提高认证的识别率。实验结果表明,该方法能取得较好的认证效果。
Keystroke rhythm is an identity authentication technique which takes persons behaviour characteristics as the basis. The PR-RP model were analyzed, in which four critical datasets were chosen, P-P and R-R relay dataset were rebuilt, and only the keystroke characteristics of password were processed. And then, a new characteristics template was buih and real- time updated, which made the data in template always be the latest characteristics, so as to improve the recognition rate of authentication. Satisfied verification effects were achieved from the experimental data.
