What is the most common ridge pattern?

We found that the most common one was the loops with sixty to sixty five percent. We also found out that whirls is the next common fingerprint with thirty to thirty five percent. The least common would be arches or ridges with five percent.

What is a fingerprint ridge?

In the biometric process of fingerscanning, a ridge is a curved line in a finger image. Some ridges are continuous curves, and others terminate at specific points called ridge endings. Sometimes, two ridges come together at a point called a bifurcation. Ridge endings and bifurcations are known as minutiae.

What are the 3 main types of ridge patterns in finger prints?

Friction ridge patterns are grouped into three distinct types—loops, whorls, and arches—each with unique variations, depending on the shape and relationship of the ridges: Loops – prints that recurve back on themselves to form a loop shape.
