identification techniques

Identification techniques are methods used to determine the identity of a person, object, or substance reliably. For individuals, this can involve fingerprint analysis, facial recognition, or DNA testing, which compare unique features to known data. For objects or substances, techniques include comparing physical characteristics, chemical composition, or using advanced instruments like spectrometers or microscopes. These methods help verify identities with high accuracy, ensuring proper authentication in various fields like security, forensics, or quality control, by providing objective and repeatable evidence to confirm what or who is being identified.
