Abstract
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.
