Fingerprints: The Science Of Fingerprints

November 3, 2021

September 1 is World  Fingerprint Day . A celebration that seeks to honor Juan Vucetich (1858-1925), who saw the unique importance of the biological signs or traces of human beings when collecting evidence for a criminal case.

Juan Vucetich was an astro-Hungarian who lived in Argentina and there he discovered the true power of fingerprints to solve unsolvable crimes to date.


Anatomically, it is the structure formed in the fingertips by the papillary ridges (sweat secretion glands located in the dermis). It is a unique structure for each person, once it is defined, at week 19 of gestation, it remains unchanged throughout life. For this reason, the drawing of the fingerprint has given rise to fingerprints, a scientific identification system by comparing fingerprints.

Its scientific character is not exaggerated, since fingerprinting is based on the scientific laws of perenniality and immutability , supported by mathematical probability. This makes it one of the most widely used methods worldwide to establish the identity of a human being, since it has no margin of error and is more reliable than DNA and dental charts.

What is Fingerprint?

It is the science that aims to identify physically considered people by means of the physical impression or reproduction of Fingerprints, commonly used in Criminology.

Fingerprinting is the study of the features of fingerprints. There are no two identical footprints, although those of the univiteline twins are very difficult to differentiate. Each footprint in the world has a series of features and shapes, which create a unique pattern. That is why in series like CSI or any police film, so much emphasis is placed on collecting fingerprints.

Fingerprints in Criminology

Today, fingerprints represent one of the most secure biometric technologies, considered legitimate evidence of criminal evidence anywhere in the world.

The comparative study of fingerprints and fingerprints left at the scene of a crime lead to the conclusive resolution of judicial cases, where these traces are undeniable evidence of the presence of a subject, determined at the scene of a crime.

For a long time, the most common method consisted of impregnating a finger with a coloring substance and pressing the fingertip against a paper. In this way, the fingerprint was obtained. However, fingerprinting currently uses digital tools to capture, print and store the fingerprint.

If we were to manually identify the billions of fingerprints that exist, it would take more than 10-15 years. Without going any further, the new smartphones incorporate the fingerprint as a method to unlock the mobile phone.

I am a person with great restlessness and curiosity to learn, discover what I do not know, as well as reinvent myself daily, someone who is curious about life and wants to know. I enjoy sharing knowledge.
This is my personal project but I also collaborate in other blogs, it is the case, the most important web on water currently exists in the US, if you are interested you can read my articles here.
