BIO - FINGER PRINT SYSTEM |
Biometrics:
Biometrics
refers to the automatic identification of a person based on his/her
physiological or behavioral characteristics. This method of
identification is preferred over traditional methods involving
passwords and PIN numbers for various reasons: (i) the person to be
identified is required to be physically present at the
point-of-identification; (ii) identification based on biometric
techniques eliminates the need to remember a password or carry a token.
With the increased use of computers as vehicles of information
technology, it is necessary to restrict access to sensitive/personal
data. Adding biometric techniques can prevent unauthorized access to an
area or a building. Cards or PINs may be forgotten, and
token based methods of identification like passports and driver's
licenses may be forged, stolen, or lost. Thus biometric systems of
identification are enjoying a renewed interest. Various types of
biometric systems are being used for real-time identification, the most
popular are based on face recognition and fingerprint matching.
A
biometric system is essentially a pattern recognition system which
makes a personal identification by determining the authenticity of a
specific physiological or behavioral characteristic possessed by the
user. An important issue in designing a practical system is to
determine how an individual is identified. Depending on the context, a
biometric system can be either a verification (authentication) system
or an identification system.
Finger
Print Application Center:
Biometrics
is a rapidly evolving technology which has been widely used in
forensics such as criminal identification and prison security. Recent
advancements in biometric sensors and matching algorithms have led to
the deployment of biometric authentication in a large number of
civilian applications. Biometrics can be used to prevent unauthorized
access to a computer or an area in a building.
LX Technologies is one
of the leaders in the security industry incorporating biometrics into
access control operations. The Fingerprint Verification Center uses
unique fingerprint minutiae to identify authorized employees who want
to gain access to a building or site. Typically, a person swipes a card
through a reader, which initiates the transaction. The Fingerprint
Verification Center then takes a snapshot of the person's finger at a
biometrics reader, and compares the snapshot to an index image in the
employee database. If the snapshot minutiae compares to the index
image, a match score is generated, and if above the user-definable
threshold, access is granted. Each Fingerprint Verification Center can
control six biometric readers of its own, and up to eight client
workstations via the Video Server application. Each client workstation
controls up to six biometric readers, for a total of 54 biometric
readers per Verification Center.
The
FBI Fingerprint Image Compression Standard
The
following is a summary
of the Federal Bureau of Investigation's image coding standard for
digitized fingerprints; developed and maintained by the FBI, Los Alamos
National Lab, and the National Institute for Standards and Technology.
The standard is a discrete wavelet transform-based algorithm referred
to as Wavelet/Scalar Quantization (WSQ). LX Technologies uses the FBI
Image Standard for the Finger Print Center; we also have our
system installed at
a FBI facility! LX Technologies has incorporated
biometrics
into access control for positive identification
to authorize access to a building or site.
Fingerprint
Matching:
The
following block diagram gives an overview of
the involvement in encoding/decoding fingerprint:
Fingerprint matching:
minutiae-based. Minutiae-based techniques first find minutiae points
and
then maps their relative placement on the finger.
