What Are Fingerprints?Looking at a glass cup you just had in your hands you notice you left a number of fingerprints on it. You examine each closely and you find yourself fascinated by what you see. But what are fingerprints exactly? Let us talk about that.
A fingerprint is an impression on a surface left behind by friction ridges on the surface of a finger. A friction ridge is a raised portion of the skin that is made out of a series of connected ridges. Prints are left behind due to the natural sweat from the eccrine glands of the finger. If you have ever been fingerprinted for government or work-related purposes, ink can also be used to create a fingerprint.
The process of fingerprint identification is called dactyloscopy, and is used by government and corporate businesses to ascertain the identity of specific individuals. The study of fingerprints is called dermatoglyphics. Due to the complex nature of fingerprinting and the fact that no two people have the same fingerprints, fingerprint experts have to be extensively trained in order to be competent in their field.
With biometric scanners, whenever a person places their finger on the identifier the machine determines if the friction ridge impression matches that of an authorized user stored in the device's database.
