What is the difference between one-to-one and one-to-many fingerprint matching algorithms?
A one-to-many algorithm identifies and authenticates a person using the fingerprint as the only piece of information. As the fingerprint is submitted for authentication, it is compared against all the fingerprints from all the persons enrolled until it finds a match. A one-to-one algorithm uses a specific unique identifier (like a username) to determine which person is about to attempt authentication. As the fingerprint is submitted, it is compared against only the fingerprints from the person determined by the unique identifier. One-to-one matching algorithms are simpler and therefore more secure and efficient for most biometric authentication systems. Back to page top.
