BIOMETRICS Ravi P. Agrahari (Science & Technology)
INTRODUCTION Biometrics is the Science and Technology of Measuring and Analyzing Biological data. In biometric technology, the identity of user will be identified by biological phenomena of human body. Biological structures and actions of different body parts of human body ranges from iris of eye, finger print, DNA fingerprint, gait recognition, face recognition to voice recognition can be used.
It is an Automated Method of recognizing a personbased on a - Physiological or - Behavioral characteristics(A) Physiological are related to the shape of the body.Examples include, but are not limited to fingerprint, facerecognition, DNA, Palm print, hand geometry, irisrecognition, which has largely replace retina, andodour/scent.(B) Behavioural are related to the behaviour of aperson. Examples include, but are not limited typingrhythm, gait, and voice. Some researchers have coinedthe term behaviour-metrics for this class of biometrics.
The Features measured are, - face - finger print - hand geometry - hand writing - iris - voice - blood vessels in the retina - coloration in the cornea of the eye - DNA from tissue samples
Biometric-Based Authentication Dr. S.R. RANGANATHAN, Father of Library Science said, “ The Right Book to the Right Reader at the Right Time ” At present distinguishing “The Right Person” from an imposter is the key to security and trust. Biometric based solution provide Personal data privacy Confidential financial transaction
Biometric-base authenticationapplications include Workstation Network and Domain access Single Sign-on Application logon Data Protection Remote access to resources Transaction security and Web security.
Biometric Device – Fingerprint Finger Print is - not easily borrowed, lost stolen forgotten falsified or guessed.
Biometrics and Libraries In libraries, finger print identification has the additional benefits of -o Convenienceo Customer confidenceo Prevent theft and vandalismo Prevent unauthorized & fraudulent useo Improves safetyo Accuracy and Security
Biometric Finger Scanners It consists of o A reader or scanning device o Software that converts the scanned information into Digital form and compares match points o A Database that stores the Biometric data for comparison
Biometric SystemFinger print identification process consists of two essential procedures Enrollment Authentication No person’s finger prints are identical to those of another individual!
Comparison for identification A Verification An Identification System System It conducts a one-to- It conducts a one-to- one comparison (1:1) many (1:N) to determine whether comparison to the identity is true. establish a subject’s eg. Accessing an identity. online secure data eg.Front counter source. check-in
A biometric system can operate inthe following two modes:- Verification – A one Identification – A one to to one comparison of many comparison of the a captured biometric captured biometric against a with a stored template biometric database in attempt to verify that the to identify an unknown individual is who he individual. The identification claims to be. Can be only succeeds in identifying done in conjunction the individual if the with a smart card, comparison of the biometric username or ID sample to a template in the number. database falls within a previously set threshold.
Web-Based Biometric Authentication System (WBAS)
The authentication can be done by:• Fingerprint only (needs a fingerprint reader)• Face only (needs a webcam/camera)• Fingerprint and Face (needs a fingerprint reader and a webcam/camera)
Biometrics and smart card system Biometrics add an additional layer of security to a smart card system Smart cards provide the “something you have”factor. The “Something you know”is usually a PIN Integrating a finger print scanner into a smart card reader increases security by adding “something you are”
Biometrics in INDIAIndia which is perpetually under thethreat of terrorism and securitybreach, is gearing up to adopt variousbiometric methods.It is used in•Defense and Security Industry•Police Administration•Finance Ministry (PANs)•Home Affairs (IDs)•Libraries
