We know that everyone, including identical twins, has a unique fingerprint. So, what are the ways to change fingerprints, which are used in many areas from touch phones to detecting criminals?
With the development of technology, we often use our fingerprints, which used to replace signatures. Beginning to form in the womb our fingerprintsOne of the biggest features that distinguishes us from other people. What if we told you that our fingerprints can change too?
Yes, we know that sounds interesting. “How can that be?” to your question and to surprising facts let’s take a look.
Imagine you are a cop tracking down a notorious killer…
How do you know which of the people you have detained as a suspect is the right person? She can easily change her style, whether from her clothes. Because of it, it is not difficult to change when plastic surgeries are so common. If your path has passed through detective movies once, you can easily answer this question as “Fingerprints!” you have answered. Because fingerprints are an accurate and reliable method in identification with different data. as a result of scientific research a proven fact.
Even people with the same DNA have different fingerprints!
He has the same DNA, even though we think it’s just genes. even in identical twins Finding different fingerprints is enough to refute this idea. Although the fingerprint does not change under normal conditions, it does change in some unusual situations.
So what are these unusual situations?
People who want to hide their identity by undergoing some painful operations or as a result of aesthetic procedures We can see that he rarely achieves this. Hormonal diseases or scars on the fingerprint are also among the factors that cause it.
Is every scar on our finger enough to change our fingerprint?
Of course not! A deep wound perpendicular to the fingerprint, burning the upper skin of the finger, a deep zigzag cut, a knife or remove fingerprint texture with sandpaper Methods such as these cause deformation in the fingerprint.
But small changes in the fingerprint are not enough to clearly prevent identification. taken from the undamaged area characteristic features If the number is appropriate for analysis, experts can identify that person, even if the machines are wrong.
Do our fingerprints change as we age?
Do our fingerprints age as we get older? When we say 50’s 60’s, time flies like water and we start to encounter many changes in our body as we get older. We cannot act as quickly as we did in our 20s, and we begin to experience tissue loss in our bones and muscles. As with our entire body, our fingertips also evolve over time. skin elasticity loses.
Apart from this flexibility problem, the thickening of the folds in the patterns that make up our fingerprint also causes changes. Of course, the changes that occur in the fingerprint with aging. tolerable size.
In other words, our fingerprints, which begin to form in the womb, are one of our rare features that accompany us until the end of our lives. with outside interference changes can be made.
