Recognition of adult and minor using biometrics

Abstract

Automatic recognition of adults and minor are demand for vending machines for tobacco and alcohol. The proposed method was discussed to try the basis trial for automatic recognition of adult and minor to be using the water content in skin decreases with age. In the method, near-infrared spectral characteristics of the cheek using it tends to be absorbed into water (1100∼2200nm wavelength) was measured by a spectrometer. As a result, the rate of increase in absorbance in a wavelength of about 1900nm (slopes) revealed that there is a big difference between a minor and adult. This method was used to identify adult men and women using this difference. In that case, in order to strengthen of the method, the "adult" and "minors" in addition to two categories of "unidentifiable", "non person" by adding the two categories, identified as four categories got for the recognition obtain a recognition rate of 81.8%.
