Foundations of Friction Ridge Skin The foundation of fingerprinting science lies in the anatomy of friction ridge skin, which develops in the second trimester of gestation. Expert examiners evaluate individual characteristics, known as minutiae, which include ridge endings, bifurcations, and dots.

Before the advent of digital databases, analysts relied on massive card catalogs sorted by pattern type and ridge characteristics, a laborious process that could take days to locate a match. The History and Evolution of Identification Fingerprinting as a method of identification emerged in the late 19th century, though the observation that ridges were unique dates back centuries.
Collection and Preservation Techniques Modern fingerprint collection employs a variety of techniques tailored to the surface texture and condition of the evidence. This subjective element requires years of training and proficiency testing, as examiners must account for distortion, pressure, and aging effects.

Fingerprinting science represents one of the most reliable and time-tested methods in the entire field of forensic identification. Sweat glands empty onto the surface of these ridges, leaving a mixture of water, salts, and organic compounds when a finger touches a surface.
