PRESENTATION ON BIOMETRICS

BIOMETRICS

It is the identification or verification of human identity through the measurement of repeatable of physiological and behavioral characteristics

CATEGORIES OF BIOMETRICS

Biometrics can be stored into two classes Physiological

Examples face-recognisation, fingerprints etc.

Behavioral

Examples signature and voice etc.

BASIC CHARACTERISTIC OF BIOMETRICS TECHNOLOGIES

Universality Uniqueness Permanence Collectibility Acceptability Circumvention

WORKING PRINCIPLE

Biometrics consists of a reader or scanning device software that converts the gathered information into digital form, and a database that stores the biometric data with comparison with existing records

MODES IN WORKING

Enrollment mode A sample of biometric trait is captured,

processed by computer, and stored for later comparison

Verification mode In this mode biometric system authenticates

a person’s claimed identity from their previously enrolled pattern.

BIOMETRIC MODALITIES

Face recognizing

Principle: Analysis of unique shape, pattern and positioning of facial features

Voice recognisation

Popular and low-cost, but less accurate and sometimes lengthly enrollment.

Iris recognisation:

This iris pattern are obtained through a video based image acquisition system.

Signature verification

Principle:

The movement of the pen during the signing process rather than the static image of the signature. Many aspects of the signature in the motion can be studied, such as pen pressure, the sound the pen makes.

ADVANTAGES OF BIOMETRICS

Biometric identification can provide extremely accurate, secured access to information , fingerprints, retinal, and iris scans produce absolutely unique data sets when done properly.

Current methods like passwords verification have many problems( people write them down they forget them, they make up easy to hack passwords)

Automated biometric identification can be done very rapidly and uniformly, with a minimum of training.

Your identity can be verified without resort to document that may be stolen, lost or altered

DISADVANTAGES OF BIOMETRICS

– The finger prints of those who are working in checimal industries are often affected . Therefore these companies shouldn’t use finger print mode of authentication.

– It is found that with age, the voice of a person differs. Also when the person has flue or throat infection the voice changes or if there are too much noise in the environment this method may not authenticate correctly Therefore this method is not workable all the time.

– For people affected with diabetes, the eyes get affected resulting in differences.

– Biometric is an expensive security solution.

BIOMETRIC SECURITY:

Security personnel look for biometric data that doesnot change over the course of your life

FUTURE OF BIOMETRICS

The future of biometrics holds great promise for law enforcement applications, as well for private industry uses.

Biometrics' future will include e-commerce applications for extra security on the checkout page
