Changes in Fingerprints Due to Different Skin Conditions

As we all know the fingerprint is the unique feature of all human beings which helps to distinguish people from each other and no one can alter or change it. But due to some reasons, they can be changed mainly due to physical conditions like allergy to some objects, powder, plants, food etc. Also due to some climatic changes like high temperature, high humidity etc. Also, there are a few temporary and permanent changes which can alter the changes in fingerprint skin, some times such alterations are also caused due by some technical errors while using a biometric system like while using devices with dirty fingers, sweaty hands etc.

Then there are different diseases which may also be responsible for the changes and may affect the clarity of our fingerprints and also these diseases cause loss of fingerprint or absence of fingerprint or missing of a fingerprint while collection, due to different reasons fingerprint will visible clearly.

In special conditions where there is an alteration of fingerprint due to any kind of deformity of disease which leads to abruption in the pattern and loss of fingerprint. Furthermore, the fingerprint doesn’t change naturally, over time as opposed, to other physical features that may change owning various factors. Mostly it will affect immigration, national registrations, banking transactions, Biometric recognition, and other set of things so those people are excluded from this method and require other means of verification which are less secure and more cumbersome

Skin regenerates on a continuous basis a skin cell begins its existence in the dermis's lowest layer (the base layer), which is rich in blood vessels and nerve endings. The cell migrates upward for roughly two weeks until it reaches its destination. Penetrates the epidermis the lowest layer. The epidermis doesn’t have blood vessels, but it does have nerve endings. The cells proceed through a sequence in the modification in the epidermis for another two weeks and progressively become more mature. Flattering out and approaching the surface then it expires and shed its skin the following are six skin functions. That is sensation, temperature control, the act of absorbing, safeguarding, excretion and secretion, these are the six major functions of fingerprint

There are different types of disease like Hand eczema, fingertip eczema,  Pompholyx, Pyoderma, Pitted keratolysis, Keratolysis exfoliativa, Lichen planus, pyogenic granuloma, systemic sclerosis, Raymanud's phenomenon, drug-induced skin reactions, leprosy, herpes-simplex virus, scabies, erythema multiforme  These are some diseases Causes in epidermis and dermis layer. Also, dermatoglyphics is a disease which will not have fingerprints inside our hands. It’s very impossible and less practised system to alteration a fingerprint through surgery but a case is reported in America that using the chemotherapy medicines a person tries to change his fingerprint. Also in aged people, we can find out some changes in fingerprints due to occupational scars and the Common type of skin diseases are congenial Deformity, cellulitis, paronychia, rheumatoid Arthritis, psoriasis, eczema, Dupuytren contracture, leprosy, blisters, These are diseases causing histopathological changes of epidermis and dermis. The sweaty hand is the other reason for fingerprint errors, tackling the issue of false rejections and false acceptance is a major role. False rejection is commonly due to some superficial injuries occurring due to the minor cuts, bruises scratches and swelling that could temporarily affect the fingerprints in a few weeks the ridges will be restored to the original shape but when the injuries on the finger are severed then it may prominently disable the fingerprint match. Besides the accidental injuries and the wounds, certain ailments might also hamper the proper induction through the fingers. Even if the fingerprint changes temporarily (due to wounds or bruising)it returns after the finger recovers .criminals became aware of this and began to device means to get around the identification systems which ranged from inventive to down write nasty by burning the fingertip skin ( fire acid or another corrosive agent), or by employing plants, it is possible to remove, change, or even fake fingerprints ( made of glue latex, silicon ) surgery ( totally altering the skin, creating a pattern alteration- sections of skin are removed from a finger grafted back in different places, such as rotation or “Z" cuts, transplantations of an area from other parts of the body such as other fingers, palms, toes,  and sole but these are less practised due to high risk and pain.

Skin diseases have a great negative impact on the fingerprint recognition process and cause problems for people suffering from skin diseases. These people are discriminated against because they cannot use the fingerprint recognition system that is very common today. Currently, there is no database of fingerprints affected by skin diseases. As the first step in this extensive and complex research, we designed and developed a special sickle fingerprint collection station. Through this station, medical experts captured the first version of this special fingerprint database Changes in dermatoglyphics and fingerprints may have serious medical-legal effects. In this case, the treating physician's proof of the condition seems to be a way to save the patient from any inconvenience. At the same time, doctors and forensic experts must be cautious, especially when the well-known criminals spare no effort to change their fingerprints to hide their identities.
