1:N Identification

Authentication whereby an identity is captured and compared with all previously captured identities. The search results are used to establish the identity of a person. In short, a 1:N Identification answers the question:

• Who is this person and are they unique?

Examples of a 1:N Identification include any place that requires Social Security Number (SSN), ID/Passport issuance, Verisoul's Liveness & Uniqueness solution, etc.

1:1 Verification

Authentication whereby an identity is captured and compared with a single previously captured identity. In short, a 1:1 Verification answers the question:

• Is this person who they claim to be?

Examples of a 1:1 Verification are Apple's FaceID, CLEAR travel biometrics, inputting a PIN at a bank ATM, etc. This approach is usually made more secure by adding an additional "factor" of authentication like having possession of a phone, password, etc.
