![]() ![]() In 1823, another physiologist, Jan Purkinje, indicated at least nine different patterns in human fingerprints. The ridges and loops present in the fingerprint were first noted by physiologist Marcello Malpighi when he examined fingerprints with the help of a microscope in the year 1686. Ancient Chinese were a step ahead of Babylonians and used ink to register their fingerprints on paper for business and identification purposes. History shows fingerprints being recorded many centuries ago, though they were not as refined as they are now.īack then, Babylonians used to press the tips of their thumbs and fingers into clay tablets and seals and used these as signatures to record business matters. The use of fingerprints dates back to ancient times. This way, fingerprints are even more unique than DNA. So even if they fool everyone with their identical looks, they cannot cheat the fingerprint testing. They might have the same DNA, which is the genetic material in a human being’s cells, but they cannot have the same fingerprints. Fingerprints are so unique that even two identical twins have different fingerprints. Every finger, or toe, has a unique fingerprint that is different from other fingerprints. There is one in sixty-four billion chances that an individual’s fingerprint matches exactly with another individual’s fingerprint.Īdding to the uniqueness, even two fingers of the same individual cannot have the same fingerprints. Fingerprints are totally unique no two humans have been found to have the same fingerprint pattern. It is different in every individual’s case. This ridged pattern is found not just on our fingertips but also on our toes, soles, and palms. Access to buildings and restricted areasįingerprints refer to the patterning formed by the ridges found on an individual’s fingertips.Access and authentication for digital devices.Law enforcement and criminal investigation agencies. ![]() Applications of fingerprints in daily life.This is because fingerprints are the key elements in solving crime cases. However, the major usage of fingerprints lies with criminal investigation authorities and law enforcement agencies. Many institutions like hospitals and banks use fingerprint recognition for security purposes. This is precisely how criminal investigators are able to collect fingerprints from the crime scenes.įrom biometric identification to criminal investigation, fingerprints are used for a variety of purposes. Have you ever wondered how such a teeny tiny fingerprint pattern gets transferred to other surfaces? Well, this is because each ridge has sweat glands that produce sweat, and as a result, your fingerprint ridges are transferred to the surfaces you touch. Injuries like burns or cuts also have no effect on the ridge structure of fingerprints. Even though they might diminish a little when an individual grows old, they do not change or alter with age. This is what makes their fingerprints unique. Fingerprints are the result of little friction ridges that are present on the end of an individual’s fingers, thumbs, and toes and are arranged in a pattern of spirals and loops.Įvery individual has a different number, shape, location, and overall structure of their ridges. The answer lies in the patterns of fingerprints. We often wonder how criminal authorities use fingerprints to identify murderers and what lies beneath fingerprint identification. The fact that no two fingerprints are alike, not even in the case of twins, often leaves many people amazed. ![]()
