The recent advances of information technologies and the
increasing requirements for security proposed have led to a
rapid development of automatic personal identification
systems based on biometrics. Biometrics refers to identify an
individual based on his or her distinctive physiological (e.g.,
fingerprints, face, retina, iris) or behavioral (e.g., gait,
signature) characteristics accurately [1]. It is inherently more
reliable and more capable than traditional token-based or
knowledge-based methods in distinguishing between an
authorized person and a fraudulent impostor. Among all
biometrics, fingerprint recognition is one of the most reliable
and promising personal identification technologies.
Biometrics authentication is highly reliable, because
physical human characteristics are much more difficult to
forge the security codes, passwords, hardware keys sensors,
fast processing equipment and substantial memory capacity,
so the system are costly. Biometric-based authentication
occupied by varying applications such as, workstation and
network access, single sign-on, application log on, data
protection, remote access to resources, transaction security,
and Web security. Moreover, a promise of e-commerce and egovernment
can be achieved through the utilization of strong
personal authentication procedures.
Secure electronic banking, investment and other financial
transactions, retail sales, law enforcement, health and social
services are already benefiting from these technologies.
Biometric technologies are expected to play a key role in
personal authentication for large-scale enterprise network
authentication environments, Point-of-Sale and the protection
of applications. Utilized alone or integrated with...

Cancellable biometrics uses transformed or intentionally
distorted biometric data instead of the original biometric data
for identifying person. When a set of biometric data is found to
be compromised, they can be discarded, and a new set of
biometric data can be regenerated. Several keys issues in
generating cancellable biometrics can be defined as
changeability (how dissimilar the transformed data are
compared to the original data), non-invertibility (transformed
biometric data should not be easily converted back to the
original biometric data even if the transformation method is
known and the transformed data are given), reproducibility (we
should be able to generate many different cancellable templates
from the original data), performance degradation (the
performance when using transformed templates should not be
degraded much).

Is Biometrics A Ultimate Technology? Essay

- BIOMETRICS As humans, we have always had the need and urge to identify the people around us. With the massive rise in population, this urge has gradually transformed into a necessity. We have typically used passwords or physical identification in the form of driver’s license, passport, etc. as proof of identity. However, with the increase in incidents of frauds and thefts where illegal or stolen documents have been produced to get unauthorized access, and rise in the cases of identity thefts, it is clear that we cannot rely on physical identification alone to identify a person with 100% certainty....   [tags: Biometrics, Facial recognition system]

History Of Biometrics Essay

- History of biometrics: What is Biometrics. The term “biometrics” originated from the Greek words “bio” meaning life and “metrics” meaning to measure. (Rouse, 2015) Biometrics is the statistical analysis and measurement of people's physical and behavioral characteristics. The main use for the technology is for identification and access control. (Mayhew, 2015) The basic premise of biometric authentication is that an individual can be identified by his or her unique physical or behavioral traits since no two persons biological characteristics exactly the same....   [tags: Biometrics, Biometrics in schools]

Essay The Importance Of Biometrics

- Biometrics is the measurement and statistical analysis of people's physical and behavioral characteristics. The technology is mainly used for identification and access control, or for identifying individuals that are under surveillance. The basic premise of biometric authentication is that everyone is unique and an individual can be identified by his or her intrinsic physical or behavioral traits. (The term "biometrics" is derived from the Greek words "bio" meaning life and "metric" meaning to measure.) There are two main types of biometric identifiers: 1. Physiological characteristics: The shape or composition of the body....   [tags: Biometrics, Facial recognition system]

Biometrics As A Tool Of Identification For Accessing A Computer Essay example

- Biometrics can be used as a method of identification for accessing a computer, room, or anything where identity needs to be provided to access information or equipment. Some people resist biometrics because of the concerns in which their privacy will be invaded or they think technology is getting too intrusive on people personal lives. Biometrics is not flawless and does have some privacy related issues. There are mechanism that can be put in place which could mitigate these problems and concerns....   [tags: Biometrics, Facial recognition system]

Essay on Evolving Biometrics

- Evolving Biometrics The terms biometrics and biometry have been used since the early 20th century. It refers “to the field of development of statistical and mathematical methods applicable to data analysis problems in the biological sciences” (Biometrics Journal.) Biometrics has been used in a variety of disciplines, in which it serves a different function for each field. For example it has been used statistically in agricultural field experiments to compare the harvest of different types of wheat; for the analysis of data from human clinical experiments assessing the effectiveness of therapies for certain diseases; or for the analysis of data from environmental studies on the effects of...   [tags: Biology Biometrics Identification Papers]

Biometrics: Security 2.0 Essay

- When we hear the term “Biometrics” the first thing that comes to our minds is an advanced or futuristic security system and we automatically remember movies like Star Wars and James Bond. What do these movies have in common and how are they related to Biometrics. The answer is simple, the security system in the doors. Star Wars characters don’t use handles to open doors they use a kind of palm print scanner and in James Bond movies we can see how they open doors with fingerprint scanners, palm prints, voice and iris recognition....   [tags: Biometrics Technology Essays]
