Common questions
How does DOD ABIS differ from a civilian criminal fingerprint database?+
DOD ABIS was built around military and battlefield identification needs, capturing biometrics from detainees, local hires, and border encounters in operational theatres, rather than being populated primarily through domestic arrest bookings.
Why does DOD ABIS hold iris data alongside fingerprints and DNA?+
Multimodal capture improves identification reliability in field conditions where fingerprints may be degraded by injury or environment, and iris recognition offers a fast, non-contact alternative that complements the other modalities held in the system.
