Different Fingerprint Types Affect the Verification Process
Fingerprint verification is the oldest, cheapest and most popular biometric scanning method because fingerprint types are unique to each person. The first recorded use of fingerprints for identification was in 1858. With advances in computing capabilities by the 1960s, fingerprint identification is now a highly automated technique. Fingerprints are examined for external characteristics, specifically the friction ridge patterns unique to every individual.
Fingerprint identification is popular because of the inherent ease in acquisition, and the numerous sources (10 fingers) available for collection.
The two main categories of fingerprint matching techniques are minutiae-based matching and pattern matching. Pattern matching simply compares two images to see how similar they are. Pattern matching is usually used in fingerprint systems to detect duplicates.
