摘要
心音信号是人体最重要的生理信号之一,在不同的人身上有着不同的特征并且具有较高的稳定性,可以作为生物认证技术的认证特征。该文在GMM动态阈值算法基础上,开发了一种基于射频识别的心音身份认证系统,实现了用户身份注册、身份认证功能。
Heart sound is one of the most important physiological signal of human body. Because ot the totauy different characteristics and high stability in various people, heart sound can be used as biometric verification feature. In this paper, based on GMM dynamic threshold algorithm and radio frequency identification technol- ogy, we develop a heart sound verification system. The system realizes identity registration and verification.
