Fingerprint information was introduced at Scotland Yard in 1901. Everyone has a fingerprint on the tip of their fingers and every person’s fingerprint is different. The patterns of furrows and ridges of a fingerprint are unique to every person.
Fingerprint information is used for many different things to identify a person. When a crime is committed, the authorities will come to the scene and look for any fingerprints that might have been left behind.
If there are any fingerprints found then they are dusted and lifted off of the item and scanned through their system. If a match is made then they will be able to determine the suspect they need to find.
Even though no one has the same fingerprints there are only three different types. A person will have either loop patterns, arch patterns or whorl patterns. These classifications help detectives when they are trying to match prints with a name.

If a person does not have fingers there are other ways to still get the prints from a person. A footprint or a palm print works the same way that fingerprint information is used.
There are several stages that are involved in fingerprint scanning, verification and identification. The first stage involves the fingerprint image acquisition. Next is the processing stage of the fingerprint image. Here, the distinctive patterns, furrows and ridges of the fingerprint are examined to find a match to the fingerprint templates and files stored in the database.
The next stage will be the location of distinct characteristics in the fingerprint image. Since fingerprint patterns, furrows and ridges are unique, the scanner will look for those distinct loops, swirls and arches.
