What does dactyloscopy mean?
Dactyloscopy is the forensic examination and comparison of fingerprints, usually to identify a person or connect someone with a crime scene. The word is especially associated with criminal investigation, although the technique is also used in legal, security, and identification contexts. Dactyloscopy depends on the distinctive pattern of friction ridges found on the fingers; even a partial or degraded print can sometimes provide a reliable comparison. In popular detective fiction and true-crime accounts, the term often signals the moment when a mysterious mark is identified as belonging to a particular person. It is a more technical and precise term than simply saying “fingerprint examination,” and its use usually carries a scientific or investigative association.
