Human fingerprints are detailed, nearly unique, difficult to alter, and durable over the life of an individual, making them suitable as long-term markers of human identity. They may be employed by police or other authorities to identify individuals who wish to conceal their identity, or to identify people who are incapacitated or deceased.
it is becoming increasingly apparent that some identifications can be unreliable and misreported as ‘conclusive’ when they are not. Unfortunately, the quality of fingerprint reports produced varied depending on how many fingerprints from a given individual were being matched. The best system was accurate 98.6 percent of the time on single-finger tests, 99.6 percent of the time on two-finger tests, and 99.9 percent of the time for tests involving four or more fingers
Forensic analysis of fingerprints should be able to comment not only on the existence of fingerprints, but also on the ‘activity level’ of the fingerprint evidence, i.e. how contact occurred and the age of the fingerprint. This interpretation shall determine whether the fingerprint findings are consistent with the allegations.
