Analyzing Finger Print Types

2. Understanding Fingerprint Types

3. Fingerprint Classification
Fingerprints are basically of 4 types :
1. Loop – 45-48%
2. Arch – 7-8%
3. Whorl – 45%
4. Accidental – 1%

4. Sub-Type of Loop Sub-Type of Arch a. Ulnar Loop b. Radial Loop
a. Simple Arch
b. Tented Arch
c. Tented Arch with Ulnar Loop
d. Tented Arch with Radial Loop

5. Sub-Type of Whorl 1. Target Centric Whorl 2. Spiral Whorl
3. Elongated Whorl – Target Centric
4. Elongated Whorl - Spiral
5. Double Loop Whorl
6. Composite Whorl
7. Imploding Whorl
8. Ulnar Peacock’s Eye
9. Radial Peacock’s Eye

Delta

26. Centre Delta Finger Print Type - Accidental
Finger Print Code to be updated – Of Type which is
more dominant
They have 2 or more deltas and a combination or fusion of 2 or more types of patterns not including the plain, radial or Ulnar arch. This category also includes any freak pattern or accidental formation that does not conform to any conventional type.
Centre
In given example we can observe more dominance
of Tented Arch formation with Radial Loop
formation, so we would have a Delta and Center
marked along with code as X2
Delta
