Dactylography is the study of fingerprints—the aim is identification. Its origins trace back to Greek, where daktylos is finger and graphia is writing or study. It concentrates on the patterns created by friction ridges—loops, whorls, and arches—that remain constant from birth to death. Dactylography is a basic tool of forensic science, used to link suspects to crime scenes and to determine who has the right to a certain identity.
