Identity recognition based on power spectral analysis of pulse wave signal

The identification method based on biometric identification technology application of previous research mainly on external characteristics such as fingerprint, face, but in recent years the appearing of fake fingerprints technology makes people information security be badly affected. This paper proposed an identity recognition method based on the power spectral analysis of pulse wave signal from finger. Because the pulse wave signals of each subject are unique and difficult to copy and imitate, the security of this method will be higher than that of the traditional methods. The final experiment results demonstrate the feasibility and accuracy of the proposed method.
