The fingerprint is found on the inside of each person’s feet and fingers. This regional structure, which occur from the recess and protrusion, looks like a biometric map.
The human body has 2 kinds of skin. The curved skin starting from the tips of the fingers to the wrist provides the formation of fingerprints. Fingerprints occur between 8 and 22 weeks of age on the mother’s womb. It does not change forever unless it face with very large damage like burns, deep cuts. The folds forming the fingerprints are formed by the surface reflection of folds called papilla which belongs to the outer skin. For this reason, when the finger is slightly damaged, there is no problem in recognizing the fingerprint. The outer skin is self-repair and the image of the papilla is reflected to the skin. So there is no change in the fingerprint. Each person’s fingerprint is different and every finger in a hand is also different.
It is understood that there are different fingerprints in single twins in the researches. Fingerprints which are likened to a kind of barcode system can be used as identities of people.
As long as there are no deep cuts in the fingertips, this encryption does not change throughout human life. Thus, finger recognition has become widespread. It is the most common biometric recognition system used in today world.
How to Perform a Fingerprint Scan?
Fingerprinting is not an easy process. Even if the image is not completely taken when a fingerprint is received, the identity of the person can be determined with a small number of fingerprints.
Fingerprinting has provided many benefits in different fields by the development of science and technology. This process uses in the identification of people who die in any accident, especially in the case of the identification of the person who has survived the accident. And it is one of the best methods for detecting and capturing criminals.
Fingerprints mean signature for those who are illiterate and visually impaired and who cannot sign. If stronger security is required to identify fingerprints, a few fingers or all fingerprints can be used. In some governments, the fingerprints of the right and left thumbprints are sufficient.
In Which Areas Are Fingerprint Scanning Used?
With the development of technology from day to day, fingerprints can be stored not only as images but also as codes. Various fingerprint recognition devices have been produces and the most commonly used ones are thermal, optical and capacitive.
In the fingerprint scanning using by normal equipment’s, 40-50 reference points are used. The results of the research proved that there could be no more than eight points in two different persons in the same coordinate. Thanks to the latest technologies, fingerprint images can be analyzed up to fine details. Analysis is performed using pattern recognition algorithms. During this process, side effects such as cuts, wounds, dirt, and cracked skin are reduced most. After a few more steps, your fingerprint are analyzed and separated and finally stored as code.
We can see fingerprint scan function in many places including many smartphones today. Absolutely will be used for security field for many years.
