Biometric Identification

Biometric identification: Digital biometric identification involves comparing a template generated from a live biometric sample to a previously stored biometric in order to determine the probability that they are a match. One-to-one (1:1) matching is a comparison against a single template (e.g., one stored on an eID card) and is typically used for authentication and verification. One-to-many (1:N) matching is a comparison against all or a subset of templates stored in a database, and can be used for identification (e.g., a criminal record search) or deduplication (i.e., ensuring that each individual exists only once in the database). In principle, 1:N deduplication allows identity providers to establish statistical uniqueness in a population.
