The history of the fingerprint was quite interesting. The development of fingerprints had found in ancient Babylonian, Chinese, Persian, and Roman civilizations. These fingerprints are considered the oldest friction ridge skin impressions found to date. In 1892, Sir Francis Galton established that no two fingerprints were alike.
Thumb Fingerprint: No major loop. Whorls. In a whorl, there is at least one ridgeline that makes a complete circle around the finger. There are four unique types of whorls, but all whorls have at least 2 deltas. Plain whorl: This is the simplest and most common whorl. There is one complete circuit with a spiral or circular shape.
A whorl has 2 deltas and one core and the imaginary line drawn between two deltas must cross at least one recurving ridge to call the pattern a whorl. These types of whorls are known as plain whorls. 4. Composites. Composites are the 4th category of the fingerprint pattern. They are a mixture of Arches, loops, and Whorls.

Some of the shapes have the same overall pattern, but no two are identical. Part B: Identifying fingerprint shapes and displaying the distribution of these ...
There are basically four types of fingerprint whorls. The plain with two deltas, central pocket with two deltas, the double loop whorls with two deltas and accidental whorls which have two or more deltas. Theoretically, less than 1 in 1000 people has these extremely rare fingerprints.
a fingerprint that has a whorl formation looks similar to the one pictured above forming spiral or circular patterns. There are four groups to whorls, plain (concentric circles), central pocket loop (a loop with a whorl at the end), double loop (two loops that create an s like shape), and an accidental loop (irregularly shaped).
There are four types of whorls. Plain whorls are concentric circles. The central pocket loop is a whorl at the end of a loop. An accidental loop is irregular in shape. A double loop creates an “S” like pattern. Whorls make up about 35% of all fingerprint patterns. There are two premises of fingerprint identification: permanence and uniqueness.
Since your fingerprint is unique, it is like a signature. It tells who you are. There are four main types of fingerprints: arch, loop, tented arch, and whorl. The ridges on arch fingerprints look like gentle hills. An arch fingerprint would look like this: Tented arch prints look like very steep hills. They are very similar to arch prints, but the
Accidental Whorl--- in these whorls, the composition of the pattern is derived from two distinct types of patterns with at least two deltas. Whorls which contain ridges matching the characteristics of a particular whorl sub-grouping are classified as accidental whorls. 4. Composites
Whorl Fingerprints. Whorl fingerprints are one of the three main types of fingerprints, along with loops and arches. They are characterized by circular or spiral patterns and make up approximately 30% of all fingerprints. Within the category of whorl fingerprints, there are three distinct subgroups: plain whorls, central pocket loop whorls, and ...
There are four basic categories of fingerprints: whorls, loops, arches and tented arches. The four types of prints can each have many variations. The variations can alter the meaning slightly. For instance, if a loop sits high on the fingertip, it shows more intellectual ability. A small and lower loop on the tip depicts more down-to-earth and ...
