Biometric System based on RFID and Heart Sound Verification

Zhidong Zhao, Jingjia Li, Min Liu, WeiQiang Zhao

Abstract


Heart sound is one of the most important physiological signals of human body. A new access control system using dual- authentication technology is developed based on heart sound biometric and Radio Frequency Identification (RFID). ID information of the user is acquired by RFID as the user enters the range of the access control system. Then the electronic stethoscope collects the heart sound of the user. Mel Frequency Cepstrum Coefficient (MFCC) feature is extracted to compute the model parameter in Gaussian Mixture Models (GMM). The decision of verification is made to judge whether an input heart sound signal belongs to a stated identity. The system has high security since it realizes dual identification verification of one person.
