摘要
为了提高终端应用的身份认证安全性,设计并实现了基于生物特征识别和TOTP一次性口令算法的双因子身份认证方法。该方法在用户进行身份认证时,首先采集用户的人脸和声纹数据进行比对,其次要求用户在手机上安装基于TOTP算法的动态口令APP,并在身份认证时输入一次性口令进行二次验证。实践过程中对TOTP算法进行优化,结果表明:“生物特征+动态口令”的解决方案达到了预期目的。
In order to improve the security of terminal application identity authentication,a dual factor identity authentication method based on biometrics and TOTP one-time password algorithm was designed and implemented.The face and voiceprint data of the user were collected and compared during the user’s identity authentication,users were required to install dynamic password app based on TOTP algorithm on mobile phone,and input one-time password for secondary verification during identity authentication.In the process of practice,the TOTP algorithm was optimized.The results show that the solution of“biometrics+mobile phone dynamic password”achieves the expected purpose.
