The word "biometrics" is derived from the Greek words 'bios' and
'metric'; which means life and measurement respectively. This directly
translates into "life measurement". Biometrics is the science and
technology of measuring and analyzing biological data. In information
technology,Biometrics Devices refers to technologies that measure and
analyze human body characteristics, such as DNA, fingerprints, eye
retinas and irises, voice patterns, facial patterns and hand
measurements, for authentication purposes.Why Biometric?Biometric is most
definitive, real-time tool available today and can be combined with other
tools to form more secure, easier to use verification solutions.
Recognizes individuals definitively based on physiological and behavioral
characteristics.Types of Biometrics There are basically two types of
biometrics:1. Behavioral biometrics 2. Physical biometrics Behavioral
biometric definition: Behavioral biometrics basically measures the
characteristics which are acquired naturally over a time. It is generally
used for verification. Examples of behavioral biometrics include: *
Speaker Recognition - analyzing vocal behavior * Signature - analyzing
signature dynamics * Keystroke - measuring the time spacing of typed
words Physical biometric definition: Physical biometrics measures the
inherent physical characteristics on an individual. It can be used for
either identification or verification. Examples of physical biometrics
include: * Bertillonage - measuring body lengths (no longer used) *
Fingerprint - analyzing fingertip patterns * Facial Recognition -
measuring facial characteristics * Hand Geometry - measuring the shape of
the hand * Iris Scan - analyzing features of colored ring of the eye *
Retinal Scan - analyzing blood vessels in the eye * Vascular Patterns -
analyzing vein patterns * DNA - analyzing genetic makeupAuthentication by
BiometricVerification is becoming increasingly common in corporate and
public security systems, consumer electronics and point of sale (POS)
applications. In addition to security, the driving force behind biometric
verification has been convenience.Biometric devices, such as finger
scanners, consist of:• A reader or scanning device• Software that
converts the scanned information into digital form and compares match
points• A database that stores the biometric data for comparisonTo
prevent identity theft, biometric data is usually encrypted when it's
gathered. Here's how biometric verification works on the back end: To
convert the biometric input, a software application is used to identify
specific points of data as match points. The match points in the database
are processed using an algorithm that translates that information into a
numeric value. The database value is compared with the biometric input
the end user has entered into the scanner and authentication is either
approved or denied.Biometric Systems can be controlled by two things. One
is human Physiology and other one is the Behavioral. This system can
control by using following things. (i.e. Human Face, Fingerprint, Hand,
Human Iris, DNA, Number of keystroke, Signature, Individual Voice)This
type of Biometric Machines such as access control system, time and
attendance recording. This can be also used for visitor control system,
Time and attendance software, Door Access Control and for other security.
This technology performs at very high efficiency. There is very little
possibility of error so you can trust on it for any security related
task. Following are the some advantages of the Biometric machines devices
security which makes you to believe on it.• Stolen passwords.•
Positive and accurate Identification• Highest level of security•
Impossible to forge• Serves as a Key that cannot be transferred.•
