Digital Sensors and Sensor Sysstems


Abstract: The aim of the described solution is to detect the vitality of presented measurement objects. Therefore, a capacitive sensor is used. The output signal of the sensor is a frequency. The frequency-analog output signal is depending on the humidity of the measurement object. The sampled frequencies data, monitored like dynamic time series data, have been analyzed to develop an efficient binary classifier. The classifier functions as a vitality checker. Vitality checkers are useful additional tools in the field of biometric applications to improve the security of such systems.


Keywords: Analysis of frequency-analog time series data, Vitality checker, Binary classifier.
