What is ridge characteristics (ridge detail) – in forensic science

Detailed features of the ridges found on the hands and feet, and most particularly for forensic purposes, on the fingers. There are several different characteristics that can be used to individualize a fingerprint. Collectively, these details are referred to as minutiae, and they are the key to fingerprint analysis. Once the fingerprint analyst has been provided with prints to compare, he or she selects a set of ridge characteristics to examine on both prints. Their characteristics, number, direction, location, and location relative to each other are all part of this comparison. This process is referred to as a point comparison, after which the analyst will determine that the compared prints match or do not match. Currently, there is no universal standard on the minimum number of comparison points required for a match to be pronounced.
