A task where the biometric system searches a database for a reference matching a submitted biometric sample, and if found, returns a corresponding identity. A biometric is collected and compared to all the references in a database. Identification is “closed-set” if the person is known to exist in the database. In “open-set” identification, sometimes referred to as a “watchlist,” the person is not guaranteed to exist in the database. The system must determine whether the person is in the database, then return the identity.

Identification Rate

The rate at which an individual in a database is correctly identified.


A person who submits a biometric sample in either an intentional or inadvertent attempt to claim the identity of another person to a biometric system.

Indifferent User

For example, an individual, aware that a camera is being used for face recognition, looks in the general direction of the sensor, neither avoiding nor directly looking at it.

Integrated Automated Fingerprint Identification System (IAFIS)

The FBI’s large-scale ten fingerprint (open-set) identification system that is used for criminal history background checks and identification of latent prints discovered at crime scenes. This system provides automated and latent search capabilities, electronic image storage, and electronic exchange of fingerprints and responses.

Iris Recognition

A biometric modality that uses an image of the physical structure of an individual’s iris for recognition purposes, as illustrated below. The iris muscle is the colored portion of the eye surrounding the pupil.


A biometric feature format used in the Daugman iris recognition system.

ISO - International Organization for Standardization

A non-governmental network of the national standards institutes from 151 countries. The ISO acts as a bridging organization in which a consensus can be reached on solutions that meet both the requirements of business and the broader needs of society, such as the needs of stakeholder groups like consumers and users.
