Abstract
A method capable of determining fingerprint authenticity is disclosed. The method includes capturing a fingerprint image, performing an analysis program when executed analyzing the fingerprint image using a first color model to obtain a first chromaticity coordinate corresponding to the fingerprint image, performing a conversion program when executed converting the first chromaticity coordinate into a second chromaticity coordinate, performing a verification program when executed determining whether the second chromaticity coordinate satisfies a second predetermined skin color threshold, when the second chromaticity coordinate satisfies the second predetermined skin color threshold confirming the fingerprint image is authentic, and concluding the fingerprint image is forged when the second chromaticity coordinate fails to satisfy the second predetermined skin color threshold.
