What is the fingerprint classification?

Fingerprint classification is the distribution of fingerprints into rough categories to facilitate the corresponding existing records in the system. This was crucial at a time when investigators had to rely on paper files to compare the fingerprints and needed a way to quickly narrow the possibilities to compare the fingerprints from the scene with those who are in the ensemble. Today, electronic systems make it easier and a more reliable comparison, but the classification of fingerprints can still be important to the investigators. The friction combs on the fingers are very pronounced and the possibility to have the same formula as another living person is very low. Even identical twins have different fingerprints. Scientists who study the friction comb at the fingertips have identified several wide classes based on the shapes they will find.Ars in the middle of the fingerprint. It is a relatively rare type of fingerprint pattern. The arches are another example, including common and tent arches. Finally, people can have what is known as a loop model, tode with tissue loop around the left or right. The investigator who looks at the fingerprint set can quickly determine whether they are arches, loops or beliefs.

Fingerprint classification allows further categorization in each wide category. Investigators can determine the direction of patterns in the friction ridges and may notice any special properties. Sometimes people can have strongly scarred fingers, leading to the destruction of the original pattern pattern of fingerprints and the need to match the brands that have left the scars. Fingerprint classification systems can assign numeric values ​​to different types of patterns, allowing people to come up with numeric codes to help them quickly find similar fingerprints in the file.

students who learn about the history of fingerprints can perform an exercise in which they take fingerprints and learn about the classification system of fingerprints. Can study comparison samples in classroomsNovs to learn more about different samples and subtypes. While investigators today rely primarily on computer systems to coincide with the matches, they can also manually match the fingerprints and look for characteristic features of the pattern to determine whether the sample in the crime scene corresponds to the reference, such as prints from a well -known criminal or suspect. The occasional review can also help the investigators exclude someone; If the fingerprints are arched from the crime scene and the suspect has, for example, an investigator that her fingerprints do not match those of the scene.
