IDENTIFICATION ARCHITECTURE

Large-scale biometric identification architecture

An ABIS-style architecture explains enrollment, gallery search, ranking and adjudication. CheckID is called an ABIS only when product evidence supports that classification.

BIOMETRIC IDENTIFICATION

Verification, identification and deduplication solve different problems

Uses professional 1:1 / 1:N terminology with gallery, candidate, rank, threshold and adjudication concepts.

verify

1:1 Verification

Compare a probe against the biometric reference of a claimed identity.

InputProbe + claimed identity

OutputScore + decision

FMRFNMRThreshold

verify

1:N Identification

Search a gallery and return ranked candidates according to search policy.

InputProbe + gallery

OutputCandidate list + rank

Deduplication

Search before enrollment to identify a possible prior identity.

InputNew enrollment

OutputCandidate / no candidate

Duplicate risk

Adjudication

Policy or human review may resolve ambiguous candidates; reference architecture unless implemented.

OutputConfirm / reject / escalate

REFERENCE_ARCHITECTURE

ABIS-STYLE REFERENCE

Logical identification architecture

The architecture is presented professionally without claiming CheckID is a full ABIS product unless evidence confirms it.

Capture

Face · fingerprint · iris · palm where supported.

Quality Gate

Reject or reacquire poor-quality captures before extraction/search.

Template

Generate engine-specific biometric reference.

Gallery

Index/partition enrolled biometric references.

Matcher

Perform 1:N search and generate candidate scores/ranks.

Adjudication

Policy/human review where required.

Evidence

Record context, engine/version, result, policy and audit.
