Automatic recognition of people based on fingerprints requires that the input fingerprint be matched with a large number of fingerprints in a database. The recognition of these landmarks, including shape, number, and location is an automated process by which computer algorithms filter data and match a subset of individuals with a particular print.

InHenry introduced his classification system in a comparison with bertillonage, shortly after in the Henry classification system replaced bertillonage due to its pioneering theory.

In addition, plastic prints may be formed by pressing onto a soft surface such as clay, soap, and wax.
