ABSTRACT ONBIOMETRICS
ABSTRACT: Security is a major concernfor any individual. But there are manyproblems with the current security systemsbased on passwords,IDcard-swaps etc.Thesepasswords can be lost or forgotten or in theworst case be stolen by a thief to access yourdata, bank accounts, car etc.In this regardbiometrics is getting increasing concernthese days as it measures and analyses aperson's physiological or behavioralcharacteristics such as face,hand,irisetc.These characteristics are unique to
individuals hence can be used to verify oridentify a person.
WHAT IS BIOMETRICS?
Biometrics (ancient Greek: bios ="life",matron ="measure") refers to two verydifferent fields of study and application.Biometric is the most secure and convenientauthentication tool. Biometrics measure anindividual's unique physical or behavioral haracteristics to recognize or authenticate
their identity. Common physical biometrics
include fingerprints, hand or palm geometry,retina, iris, and facial characteristics.Behavioral characters characteristics include
signature, voice, keystroke pattern, and gait.
WHAT ARE BIOMETRIC CHARACTERISTICS?
Biometric characteristics can be divided intwo main classes, as represented in figure onthe top.
• Physiological: are related to the
shape of the body. The oldest traits
that have been used for more than
100 years are fingerprints. Other
examples are face recognition, hand
geometry and iris recognition
• Behavioral: are related to the
behavior of a person. The first
characteristic to be used, still widely
used today, is the signature. More
modern approaches are the study of
keystroke dynamics and of voice
BASIC CHARACTERISTICS OF
APPLICATION OF BIOMETRIC TECHNOLOGIES :
•Universality: Every person should have thecharacteristic. People who are mute orwithout a fingerprint need to beaccommodated in some way.
•Uniqueness: Generally, no two peoplehave identical characteristics. However,identical twins are hard to distinguish.
•Permanence: The characteristics should
not vary with time. A person's face, forexample, may change with age.
•Collectability: The characteristics must beeasily collectible and measurable.
•Performance: The method must deliveraccurate results under varied environmentalcircumstances.
•Acceptability: The general public mustaccept the sample collection routines.
Nonintrusive methods are more acceptable.
•Circumvention: The technology should bedifficult to deceive
