Basics of fingerprint recognition
What is fingerprint recognition?
Fingerprint is an individual’s own biometric information and does not change throughout his/her life.
Fingerprint recognition is a technology that verifies or identifies an individual using such fingerprint
information.
Free from the risk of theft or loss, fingerprint recognition technology is being widely used in security
systems replacing PIN or cards.
Process of fingerprint recognition
Fingerprint consists of ridges and valleys. Ridge is a flow of protruding skin in a fingerprint while
valley is a hollow between two ridges. Each individual has different pattern of ridges and valleys
and finger recognition makes use of such originality and uniqueness of these patterns.
Fingerprint sensor generates 2-dimentional fingerprint image using different technology. According
to the sensing technology, fingerprint sensors are classified into optical, capacitive, or thermal.
Fingerprint template is a collection of numeric data representing the features of a fingerprint.
Fingerprint templates are saved inside the memory of BioStation and used for identification.
Secure way to protect personal information
To avoid privacy concern, Suprema’s fingerprint products do not save fingerprint images itself. It is
impossible to reconstruct a fingerprint image from a fingerprint template which is just numeric data
of the features of a fingerprint.
