Title (EN) BIOMETRIC LIVENESS DETECTION THROUGH BIOCOMPATIBLE CAPACITIVE SENSOR
(FR) DÉTECTION DE VIE BIOMÉTRIQUE PAR LE BIAIS D'UN CAPTEUR CAPACITIF BIOCOMPATIBLE
Abstract:
(EN) A method may include measuring, photoplethysmography (PPG) data and capacitance data of an object. The method may also include, with the PPG data and the capacitance data, detecting, by a microprocessor, positive peaks of the data by comparing successive measurements. The method may further include finding, by the microprocessor, a maximum peak value of the detected positive peaks, and generating, by the microprocessor, a threshold value based on detected positive peaks. If the maximum peak value is greater than the threshold value, analyze, by the microprocessor, a fingerprint of the object. The method may also include determining, by the microprocessor, based on the PPG data, the capacitance data and the fingerprint of the object, at least one of if the object is authorized or unauthorized, and if the object is a human being or not a human being.
(FR) La présente invention concerne un procédé consistant à mesurer des données de photopléthysmographie (PPG) et des données de capacité d'un objet. Le procédé peut également consister, avec les données de PPG et les données de capacité, à détecter, par un microprocesseur, des pics positifs des données par comparaison de mesures successives. Le procédé peut en outre consister à trouver, par le microprocesseur, une valeur de pic maximale des pics positifs détectés, et à générer, par le microprocesseur, une valeur seuil sur la base de pics positifs détectés. Si la valeur de pic maximale est supérieure à la valeur seuil, le procédé consiste à analyser, par le microprocesseur, une empreinte digitale de l'objet. Le procédé peut également consister à déterminer, par le microprocesseur, sur la base des données de PPG, des données de capacité et de l'empreinte digitale de l'objet, si l'objet est autorisé ou non autorisé et/ou si l'objet est un être humain ou non.
