Your identity at the tips of your fingers: things you need to know
What do you know about your fingers? What do they know about you? There are things you definitely need to know. Learn more about them from the following article!
One can be easily distinguished by his/her fingerprints. Thus, it's a very serious natural document of a person.
What do you know about the nature of fingerprints?
As it turns out, fingerprints were taken even at the time of ancient dynasties
The tradition of taking fingerprints comes from China. First records from Qin Dynasty dated 221-206 BC contain information about fingerprints as evidence during burglary investigations.
The Chinese also used marks left by their fingers to protect clay seals during Qin and Han Dynasties (221 BC - 220 AD).
In modern history, the first person who offered to define criminals by their fingerprints was Henry Faulds in 1880.
A bit later, Francis Galton proved that there are no identical fingerprints. He was also the first person to collect fingerprints cards. The government of Great Britain saw some sense in Galton's theories and used it to identify the perpetrators.
Many criminals tried to change or remove their fingerprints
Though there is almost no way of permanently changing your natural fingerprint, there have been several attempts to do so. John Dillinger burnt his own prints off with acid. Another criminal used skin transplantation from his chest to his fingers. Forensics experts say, only a permanent damage to the skin tissue can remove your fingerprints. If skin regenerates, it will restore its unique friction ridge patterns. Even after death, a body can be identified by them.
Animals also have unique fingerprints
Cats and koalas have unique fingerprints too. Cats and dogs also have unique noses.
After identification by fingerprints has been introduced in smartphones, experiments show that fingerprint sensors might work for your pets. But don’t be afraid – they won’t unlock your phone without your strong intention to help them to do so.
Fingerprints do not only identify you, they also protect your skin
Epidermal ridges help transmit signals to sensory nerves in texture perception, amplifying triggered vibrations when i.e. they rub against an uneven surface. These ridges also create a better surface contact for firm gripping and can be used as protection when you touch rough materials.
Can your fingerprints be confused with someone else's?
- Up to this day, no identical fingerprints have been found.
- Still, there is a chance that your fingerprints can be confused with someone else’s.
- Statistically, there is a percentage of false positive matches of 0.1 percent. Since the total fingerprint intake nowadays is huge, thousands of people can be subjects to false positive identification.
- Several genetic deviations are characterized by the absence of fingerprints. If there are no other symptoms but smooth fingers, this is called “Adermatoglyphia” and can cause a lot of trouble to people at a police check.
- Probably, this is the reason there are several other ways of identification, like iris or tongue recognition.
What information about you do your fingerprints contain?
If by any chance there’s no your personal record in FBI, your gender can be identified by fingerprints. Not much? Read further!
Are there any other means of identification?
Recently other unique features of a human organism have been found and have already been accepted by several courts in the United States as a tool of personal identification. These data can tell much more about you than fingerprints, e.g. about your health, environment, diet, and genetics. Thus, they can be used not only in courts for establishing the guilt or purgation, but also for establishing proper medical treatment when no personal records are available.
That makes more sense in providing your “fingerprints” to officials, what do you think?
