Identification

Identification is the process of establishing or verifying the identity of an individual or object. Identification typically involves comparing a set of characteristics or traits, such as fingerprints, DNA, or facial features, to a reference or database to determine if there is a match. Identification is used in a variety of contexts, including security, forensics, and personal identification. For example, a police officer may use identification to determine if a suspect is a known criminal, or a border control agent may use identification to verify the identity of a traveler. Identification can be done manually, using visual inspection or other methods, or it can be done automatically, using computer algorithms or other technology.
