INDIVIDUAL IDENTIFICATION METHOD
The present invention relates to an individual identification method. The method comprises the steps of: inputting a photoplethysmograph (PPG) signal of an individual; pre-processing the inputted PPG signal using a bandpass filter; detecting a feature point based on a pulse-to-pulse interval (PPI) f...

| description | The present invention relates to an individual identification method. The method comprises the steps of: inputting a photoplethysmograph (PPG) signal of an individual; pre-processing the inputted PPG signal using a bandpass filter; detecting a feature point based on a pulse-to-pulse interval (PPI) from a PPG signal outputted through the pre-processing step; detecting a feature point of an autoregressive(AR) coefficient according to a linear prediction analysis from the PPG signal outputted through the preprocessing step; and identifying the individual by classifying patterns of the PPI-based feature point and the feature point of the AR coefficient, thereby easily identifying the individual using the PPG signal of the human body.
본 발명은 개인 식별 방법에 관한 것으로, 개인의 PPG(photoplethysmograph) 신호가 입력되는 단계와, 상기 입력된 PPG 신호에 대해 대역통과필터를 이용하여 전처리하는 단계와, 상기 전처리하는 단계를 통해 출력된 상기 PPG 신호로부터 PPI(pulse to pulse interval) 기반의 특징점을 검출하는 단계와, 상기 전처리하는 단계를 통해 출력된 상기 PPG 신호로부터 선형 예측 분석에 따른 AR(autoregressive) 계수의 특징점을 검출하는 단계와, 상기 PPI 기반의 특징점 및 AR 계수의 특징점의 패턴을 분류하여 상기 개인을 식별하는 단계를 포함함으로써, 인체의 PPG 신호를 이용하여 개인을 쉽게 식별할 수 있다. |
