Is there a connection between hand fingerprints and foot fingerprints?

From the fingerprint 4 months the fetal selection has been formed and has become one of the basic physiology of each person's physical characteristics. The fingerprint features are quite fixed and do not change with the person's age, or physical health, and each person's fingerprint is different. Along with the basic theory of fingerprint recognition technology, Henry pointed out that each fingerprint system is generally 70-150 basic feature points.

From a probability point, as long as the feature points of two fingerprints match 12-13 can be determined as the same fingerprint, and the probability of the occurrence of the two fingerprints exactly 120 years ago.

Fingerprint features are generally divided into general features and local features. The overall function includes the classification of grain shape (bow ring, spiral type), feature points (endpoints, bifurcation points, divergence points, isolated points, ring points, short grains), direction, curvature, position. Each feature point has about seven features, and our ten fingers produce a minimum of 4900 independent features.

Experts believe that the presence of fingerprints, based on the characteristics of fingerprints and non-replicable, separately independent fingerprints, is unique. One of six billion fingerprint points at the same rate.

Fingerprints are different everywhere!! What should I do if my fingerprint is broken and you can't turn on your phone? Naturally, it can also be opened. Because your fingerprints are in your flesh, not the skin, and it's because the flesh of your fingerprints is long when you're long.

Grain is a strange spiral pattern in nature. Humans all have fingerprints, and they can easily identify different people. This is because each person's fingerprints are unique, so how are they formed and why do they reflect the information?

The inner surface of our palms, fingers, feet, and toes have uneven lines, and the generation of these lines is extremely beneficial to us, because their presence increases the friction on the surface, making it easy for humans to grasp heavy objects with their hands. In the same way, the pattern on the tires of a car is also designed to increase the friction on the ground. As with every component of the human body, the formation of these lines is the result of a combination of genetic and environmental factors.

The heredity in DNA gives the overall "command" of how to produce the fetus during the formation stage, but the formation of its specific subtleties is a random event. The specific position in the womb at a particular time of the fetus, as well as the density of the surrounding amniotic fluid and other substances, determine the differences in the texture of each individual. In addition to the myriad genetic factors that determine how a person will be "made", there are also many environmental factors that influence the formation of fingerprints, such as the weather.

The whole process of fingerprint formation is very disorderly, and in fact, in the long history of mankind, it is impossible to form two identical fingerprint patterns. Because of this, fingerprints can be used as a special marker for a person, even if they are two twins who share the same eggs. Two fingerprints that look roughly similar can also be identified by experts or special software.

This is the basic idea of fingerprint analysis, whether in criminal investigation or security, the job of a fingerprint reader is to replace an expert, collect samples and compare them with samples that have already been recorded.
