Abstract
Fingerprint verification is an important biometric technique for
personal identification. We describe the design and implementation of a
prototype automatic identity-authentication system that uses
fingerprints to authenticate the identity of an individual. We have
developed an improved minutiae-extraction algorithm that is faster and
more accurate than our earlier algorithm (1995). An alignment-based
minutiae-matching algorithm has been proposed. This algorithm is capable
of finding the correspondences between input minutiae and the stored
template without resorting to exhaustive search and has the ability to
compensate adaptively for the nonlinear deformations and inexact
transformations between an input and a template. To establish an
objective assessment of our system, both the Michigan State University
and the National Institute of Standards and Technology NIST 9
fingerprint data bases have been used to estimate the performance
numbers. The experimental results reveal that our system can achieve a
good performance on these data bases. We also have demonstrated that our
system satisfies the response-time requirement. A complete
authentication procedure, on average, takes about 1.4 seconds on a Sun
ULTRA I workstation (it is expected to run as fast or faster on a 200
HMz Pentium)
