Friction Ridge Analysis

Friction Ridge Analysis involves examining the unique patterns of ridges and valleys on fingerprints and similar skin areas. These patterns, known as friction ridges, are distinctive to each individual, like a biological fingerprint. Experts analyze the shape, arrangement, and details of these ridges to identify or verify a person's identity. This method is widely used in criminal investigations, security systems, and personal identification due to its high accuracy, as no two people (even identical twins) share the same ridge patterns.
