Fingerprint identification, known as dactyloscopy,
[8] or hand print identification, is the process of comparing two instances of friction ridge skin impressions (see
Minutiae),
from human fingers or toes, or even the palm of the hand or sole of the
foot, to determine whether these impressions could have come from the
same individual. The flexibility of friction ridge skin means that no
two finger or palm prints are ever exactly alike in every detail; even
two impressions recorded immediately after each other from the same hand
may be slightly different. Fingerprint identification, also referred to
as individualization, involves an expert, or an
expert computer system operating under
threshold scoring
rules, determining whether two friction ridge impressions are likely to
have originated from the same finger or palm (or toe or sole).
