How Does Fingerprint Matching Work?
Fingerprint matching works by comparing two sets of fingerprints for similarities and differences. The fingerprint pattern on the left thumb, for example, is compared to the pattern on the right thumb. By comparing the patterns, analysts can determine if the fingerprints belong to the same person or not. There are three basic patterns of fingerprints: arches, loops, and whorls. Arches have no delta, loops have one delta, and whorls have two deltas. A delta is a ridge point where two ridge lines meet.
How Accurate is Fingerprint Matching?
Fingerprint matching is a highly accurate method of identifying individuals. The chance of two people having the same fingerprints is 1 in 64 billion. This is why fingerprints are used so extensively in forensic science. However, fingerprint matching is not infallible. Mistakes can be made in the comparison process, and sometimes there may be smudges or other imperfections in the fingerprints that make it difficult to determine a match.
How is Fingerprint Matching Used in Criminal Investigations?
