Fingerprint authentication is a sub-branch of biometric authentication. No two individuals have the same fingerprints, even identical twins have different sets of fingerprints. What’s fascinating is that these do not change, even as people age, their fingerprints remain the same.

In general, there are 3 main fingerprint models (belt, ring and spiral). The lines on the inner surfaces of the fingers are called papillary lines. Papillary lines are formed by the combination of sweat glands and nerve endings under the skin. They are unique to each individual both in the number of lines they have and their character. The differences are actually quite distinctive. Based on these, it is possible to identify personal attributes such as race, gender, and nationality from someone’s fingerprints. When it comes to gender, due to the different physiological, biochemical, and anatomical elements of each sex, there are noticeable differences between the fingerprints of men & women. The key indicators are found in the spacing of the pores and the thinness of the papillary lines.

While fingerprint identification is a cost effective and efficient method of identifying members of the population, it is more difficult if the identification process is taking place post-mortem. As remains dry, swell, char or decompose, retrieving accurate data on the person’s fingerprints can become very challenging. That is why in the event of a tragedy it is imperative that the fingerprint’s are secured early in the post event process.
