HOW YOU DEVELOP A UNIQUE FINGERPRINT?

HOW YOU DEVELOP A UNIQUE FINGERPRINT?

Fingerprints are the little ridges on the tips of your fingers. These are folds of the outer layer of skin, the epidermis. The “prints” are the patterns of skin oils or dirt of these ridges leave behind on touching a surface.

Fingerprints became a popular form of bio-metrics because they are easy to access, classify and sort. Fingerprints are Unique and Permanent, this quality of fingerprint make it an infallible means of personal identification, because the ridge arrangement on every finger of every human being is unique and does not alter with growth or age.

You might be wondering the EFFECT OF INJURIES ON FINGERPRINT

Your boyfriend/girlfriend or husband/wife might leave you but your fingerprint will never!

It was only in 2015 that a long-term study showed that fingerprints are stable over a person’s lifetime. The ridges of a fingerprint are visible on the skin’s surface layer, but the pattern is actually “encoded” below that. Even if you have a major skin injury, your prints will come back when the outer layer heals – though you might have a scar, too.

Injuries such as superficial burns, abrasions, or cuts do not affect the ridge structure or alter the dermal papillae, and the original pattern is duplicated in any new skin that grows. This characteristics of fingerprint (unique and permanent) was described by Henry Faulds and William James Herschel. Their observations were experimentally verified by the English scientist Sir Francis Galton, who suggested the first elementary system for classifying fingerprints based on grouping the patterns into arches, loops, and whorls.

However, in some cases, damage to a fingertip extends deeply into the skin’s generating layer, resulting in permanent changes to the fingerprint. Experts note- the scar produced – be it from a burn or a cut – can itself become permanently encoded into the fingerprint pattern.

HOW UNIQUE IS YOUR FINGERPRINT FROM OTHER?

“Everyone is unique in their own way”, well fingerprint have sworn to this phase. You will believe this statement.

There's a one in 64 billion chance that your fingerprint will match up exactly with someone else's, isn’t it amazing?

Fingerprints are more unique than DNA, the genetic material in each of our cells. Although identical twins can share the same DNA or at least most of it but they can't have the same fingerprints. No two people end up with exactly the same fingerprints, even identical twins.

STORY OF FINGERPRINT DEVELOPMENT

Fingerprints began to form before birth. When a fetus starts to grow, the outside layer of its skin is smooth. But after about 10 weeks (more than 2 month), a deeper layer of skin, called the basal layer, starts growing faster than the layers above it, which makes it “buckle” and fold. The expanding lower layer ends up scrunched and bunched beneath the outside layer.

These folds eventually cause the surface layers of the skin to fold too, and by the time a fetus is 17 weeks old (more than 4 month)– about halfway through a pregnancy – its fingerprints are set.

This folding process might sound random, the overall size and shape of fingerprints are influenced by the genes you get from your parents. So you probably share some fingerprint patterns with your family members. But the details of your fingerprints are influenced by many other factors besides genes. For example, the shape and size of the blood vessels in your skin, how fast the different layers of skin are growing, and the chemical environment inside the womb all play a part.
