Abstract
(EN)
The invention discloses a method of recognizing a living body. After video information when a to-be-recognized user reads aloud a verification content is acquired, the mouth feature information of the user is acquired according to the video information, whether the mouth feature information of the user is matched with a reference lip language feature sequence corresponding to the verification content in a lip language database is further judged, and if yes, the to-be-recognized user is determined to be a living body. The user does not need to execute complicated actions during the recognition process, the actions executed by the user are easy to recognize, and on the basis of simplicity, convenience and easy execution, the use experience of the user is improved and the safety is also ensured.

本申请公开了一种活体识别方法。在采集待识别的用户在朗读验证内容时的视频信息后,根据视频信息获取用户的嘴部特征信息,并进一步判断用户的嘴部特征信息与唇语库中验证内容对应的参考唇语特征序列是否相匹配,若匹配,则将待识别的用户确认为活体。用户在该识别过程中无需执行复杂的动作,而用户所执行的动作也易于识别,从而在简便且易于实施的基础上,提高了用户的使用体验,也保证了安全性。
