Then we Composition of Latent Fingerprints: Types of Glands 1. Fingerprint identification is based primarily on the minutiae, or the location and direction of the ridge endings and bifurcations (splits) along a ridge path. Loops are the most common, occurring 60-65% of the time. Identify ownership. Analysts classify fingerprints into three categories according to the type of surface on which they are found and whether they are visible or not: Fingerprints on soft surfaces (such as soap, wax, wet paint, fresh caulk, etc.) Before computer databases, technicians compared the fingerprints of suspects to each print file, looking for identical matches in the unique patterns of a print. A bifurcation is the spot where a ridge splits into two ridges. Fingerprint (FP) representations of chemical structure continue to be one of the most widely used types of molecular descriptors in chemoinformatics and computational medicinal chemistry.

Unlike the rest of the patterns, the loop has three sub-categories:Ulnar Loop –In this pattern, the ridges turn backward, but they don’t make a full turn. ...Radial Loop – This pattern is similar to the ulnar loop, but the difference is the turns point toward the thumb instead of the small finger.Central Pocket Loop –The ridges in this pattern re-curve to surround the central whorl. People have various types of fingerprints, including loops, whorls, and arches. This is the rarest type of fingerprint. Latent fingerprints are made of the sweat and oil on the skin’s surface. The validity of fingerprint evidence is based upon two basic principles: no two people have the same fingerprints and a person's fingerprint patterns never change. The loop was determined to be the most prevalent, accounting for 60 to 65 percent of the total. Fingerprint sensors are classified into optical fingerprint sensors, semiconductor capacitive sensors, semiconductor thermal sensors, semiconductor pressure-sensitive sensors, ultrasonic sensors, and RF sensors according to the sensing principle.
