2 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, the fingerprints are not save
itself. It is impossible to reconstruct a fingerprint image
from a fingerprint template which is just numeric data of
the features of a fingerprint.
