Biometrics are the use of a person’s physical characteristics or personal traits to identify or verify the claimed identity of that individual. These can include fingerprints, face, vein pattern, eye, iris print, DNA, blood, voice, gait, or signature. Private entities and public authorities have increasingly used biometrics to validate and identify individuals, granting or restricting access to locations, services, or devices. Public sector users include law enforcement and security agencies, criminal justice, immigration, and social welfare processes (including to prevent identity fraud and theft) and the authentication of beneficiaries of humanitarian aid.
