What is the science of fingerprints?

Human beings were born with ridges that form solid patterns on each of their fingers. These ridges consist of loops, arches and beliefs that are unique for every human being, even the same twins. As a result, physical evidence of fingerprints can be used to positively identify an individual. The fingerprint science involves the process of gathering this evidence and then verification and analysis of the evidence to identify the individual. Formal name for fingerprint science is dactoscopy

Many entities regularly use fingerprint science to identify individuals. For example, the police department can use fingerprint technology to charge criminals or identify a dead body. The prosecutor may, on the basis of a positive identification of fingerprints, stand the whole case against the defendant. Military regimes can use fingerprint science to identify an officer who has been seriously injured or killed.

There are usually two Key steps connected to fingerprints:Identifying fingerprints and comparing fingerprints. Within the identification process, the examiner must find and collect any available latent and patent fingerprints. Latent prints usually refer to the fingerprints of the ridges that are unintentionally left on the surface and which are not visible to the naked eye. Using scientific techniques and powders or chemicals of fingerprints, experts can make latent prints visible during the collection process.

patent prints , on the other hand, remain behind the surface or fingerprint when the fabric is moved from the finger to the surface or reader. For example, the patent printing would result in if the person soaked the finger in color and then pressed it on the canvas. Patent prints can usually be identified without chemical processing and are often considered more reliable than latent prints.

Once the fingerprints are identified, the printing must be compared. FromBorns often perform authentication and comparing fingerprints using software programs corresponding to fingerprints. Generally, the software first processes fingerprint images using algorithms that help get clearer images of the original fingerprint. The original printing is then compared with any corresponding records in the software database to determine whether there is a probable consensus.

Fingerprint science requires more expertise than just knowing how to use fingerprint biometry technology. The examiner must also consider the impact of friction on fingerprints, especially if this print is latent. Developmental medium, skin elasticity, slipping and deposition pressure can affect the appearance of the press and competent experts must be able to analyze these other factors.
