"Biometric" come from the Greek words "bio" (life) and "metric" (to measure). Biometrics are technologies used for measuring and analyzing a person's unique characteristics. There a"Biometric" come from the Greek words "bio" (life) and "metric" (to measure). Biometrics are technologies used for measuring and analyzing a person's unique characteristics. There are two types of biometrics: behavioral and physical. Behavioral biometrics are generally used for verification while physical biometrics can be used for either
identification or verification.
What are biometric systems used for?
Biometrics are used for identification and verification:
Identification
is determining who a person is. It involves trying to find a match for a
person's biometric data in a database containing records of people and
that characteristic. This method requires time and a large amount of
processing power, especially if the database is very large.
Various Identification Methods in the World of Biometrics
The name 'biometrics'
is enough to increase the curiosity among individuals. Although it
might sound very simple, but biometrics actually describes a vast area
of security. While talking about biometrics, it is not considering only
the face recognition system but there are plenty of systems that are
based on the same field yet, their purpose is someway different.
Basically biometrics is based on recognizing the biometric features of
the individuals. It offers the security by recognizing fingerprints,
voice, retina, or face of the individuals. Different security solution
possesses different identification methods for offering security at
various places.
While
choosing the security solution for guarding the premises or other
places, it is necessary to know about all the biometric security systems
in detail. It will help you to decide, the right one for your premise.
Like every other security devices, biometric security systems have also
got some limitations. After all flaws and benefits are the two sides of
the single coin! So, while knowing about the various biometric based
products, also emphasize on the limitations so that you can take better
precautions if necessary.
Different Identification Methods:
While
talking about the security systems, let's follow the hierarchical
structure so that you could know about the efficiency of the devices
better. The various security systems can be listed as follows:
* Biometric Fingerprint System:
As
the name suggests, the device offers security by recognizing the
fingerprints of the individuals. The device is compact enough to keep
anywhere. When a person enrolls first time, the device captures the
fingerprint of the individuals and stores in the database of the
computer. When the person re-visits the premise then, the device again
captures the fingerprints and performs a matching process between the
older stored patterns and the newest captured patterns. When it finds
the match, it grants the authentication else it denies.
Limitations:
It has a number of limitations but the major ones are:
* It has a limited user capacity. Its services cannot be extended when needed.
* It is a slower process.
* Biometric Retina Scanner System:
An
amazing biometric solution is the eye scanner system. The biometric
product offers the security recognizing the retinal pattern of the eye.
The solution is based on the similar enrollment process like other
biometric products. When the user enrolls, the system stores the retinal
patterns in the database of the computer. During the return visit the
system matches the older to the newest captured patterns. If it finds
the match then it grants the authentication.
Limitations:
The major limitations are:
* It consumes a lot of time in order to grant the authentication.
*
Since it captures the retina, so any distortion of the eye can ruin the
process. So, one has to be attentive as it cannot resist changes.
* Biometric Face Recognition System:
The
latest biometric security solution is the biometric face recognition
system. The face recognition system offers utmost security by
recognizing the facial patterns of individuals. The solution performs
the face recognition process by capturing the facial details during the
enrollment process. Then, whenever the person revisits the premise the
face recognition system capture the facial details and perform the
matching process in order to grant the authentication.
The
biometric face recognition system is efficient in offering the security
at premises as well as it takes below average time to grant the
authentication. Thus, it saves a lot of productive time. It does not
have any storage limitation or strength limitation. Thus, face
recognition system can be effectively used in different premises.
There
are also a number of behavioural biometric technologies such as voice
recognition (analyzing a speaker's vocal behavior), keystroke (measuring
the time spacing of typed words), gait recognition (manner of walking),
or signature (analyzing the way you sign).
