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

​
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 include:

  • Apple’s FaceID
  • CLEAR travel biometrics
  • Inputting a PIN at a bank ATM

This approach is usually made more secure by adding an additional “factor” of authentication like having possession of a phone, password, etc.
