This paper demonstrates the identification of gender using the spatial parameters of the fingerprint. From Table2, it is clarified that the ridge count of 31 was found to be 287 times among the 4100 female fingerprints. For an unknown fingerprint, different scores are assigned for RC and FTS for male and female. RIDGE TRACING ( WHORL ) - counting the ridges intervening between tracing ridge and the right delta of whorl. Why does the original fingerprint division need modification? A human fingerprint is the representation of dermal ridges on each fingertip. The individuality of fingerprint is not based on its pattern or shape, but it is based on the ridges characteristics called as minutiae. Extesnion to FBI Henry Classification System. Now, using Eq.
