Biometrics is a security technology that identifies and verifies individuals based on unique physiological and behavioral characteristics, such as fingerprints and voice recognition. It addresses deficiencies in traditional identification methods like passwords and key cards, offering increased security and user-friendliness. Future innovations include brainwave recognition and contactless fingerprint scanning, while challenges such as costs and potential inaccuracies in voice recognition remain.

BIOMETRICS
A New Technique of Security

INTRODUCTION
 Biometrics is the term derived form Greek word “biometron” means
Bio= life & Metron= to measure.
 Biometrics defined as an tool for the identification and verification
of the person on the basis of physiological and/or behavioral
characteristics of the person.

BIOMETRIC TRAITS

WHY BIOMETRICS ?
 Physical identification takes place by using password, keys,
badges and cards, that can be lost, duplicate, stolen and
password, secret code, security question, PIN can be easily
forgotten by user, compromised and shared. Such loopholes
or deficiencies of conventional personal identification
techniques have caused major problem to all concerned.
 While for biometrics, it provides us an increased sense of
security. It is low cost identification system. It is user friendly
as people can not lose their unique traits. As compare to
plastic cards and tokens, biometrics are also eco-friendly as
they not create any type of pollution.

INTERESTING FACTS ABOUT BIOMETRIC
TECHNOLOGY
 Future method of payment
 One of the largest biometric data -India, through its Aadhaar
 The first smartphone with a fingerprint scanner - It is a lesser-known fact
that the first company to introduce fingerprint scanners was not Apple or
Samsung, it was Toshiba. Yes, Toshiba introduced this feature first in 2007.
Which was followed by HTC.
 Unmatched Uniqueness: Every individual’s biometric data is unique. For
example, even identical twins have different fingerprints and iris patterns.

Integration with AI
 Improved Accuracy: By learning and adapting to new data. For
example, facial recognition systems powered by AI can better
identify individuals in varying lighting conditions or with
changes in appearance (e.g., glasses, facial hair).
 Adaptive Learning:AI systems can continuously improve by
learning from successful and unsuccessful recognition attempts.
This means that the more the system is used, the more accurate
it becomes.
 Example:Apple Face ID:
 Apple's Face ID technology uses AI to map and recognize the
user’s face. The system learns and adapts to changes in
appearance over time, such as makeup, hairstyles, or aging. It
uses a neural engine to perform over 600 billion operations per
second, ensuring fast and accurate recognition.

FUTURE INNOVATIONS
 Brainwave Recognition: Unique brainwave patterns measured by EEG.
Example:
 Neuro-ID: EEG headsets for high-security authentication.
 Contactless Fingerprint Scanning:
 Captures fingerprint images without direct contact with the scanner.
 Reduces hygiene concerns and improves speed of scanning.

ADVANTAGES OF BIOMETRICS
 Effective technique to enhance security.
 User friendly.
 Does not use any password, PIN or secret code that are compromised.
 It used physical and behavioral traits for identification and
authentication that are difficult to compromised.
 Long lasting performance, because biometrics traits are permanence in
nature.
 Difficult to fool biometrics system.

DIS-ADVANTAGES OF BIOMETRICS
 Retina recognition required closed physical contact of the scanning
device which may not be generally accepted by public.
 Costly
 Voice recognition requires large amount of computer storage, peoples
voice can change, background noise can interfere.
 Biometric features may changes over time.
 Signature recognition has poor long term reliability, accuracy
difficulty to ensure.

APPLICATION(s) OF BIOMETRICS
 Biometrics come under the branch of “PREVENTIVE
FORENSIC”.
 It prevents unauthorized access to ATM, cell phones, desktop,
laptop.
 Criminal identification.
 Airport, Bank security.
 It is use to maintain the attendance record of employees.
 In automobiles, biometrics can replace keys with keyless entry
device.
