Methods of AuthenticationsMethods of Authentications

• There are two commonly used authentication methods. They are biometric devices and callback system

• It is a device that translates personal characteristic into a digital code that is compared with a digital code stored in the database

• Examples of biometric device is fingerprint recognition, facial recognition, hand geometry, iris scanning, retinal scanning, voice recognition and signature verification system.

Page 5: Ict  Security Measures

Fingerprint Recognition• It also measure blood flow, or check for correctly arrayed

ridges at the edges of the fingers

Facial Recognition• Analyses the characteristics of an individual’s face images

captured through a digital video camera.

Hand Geometry Scanning• Involves the measurement and analysis of the shape of one’s

hand.

Iris Scanning• Analyses the features that exists in the coloured tissues

surrounding the pupil which has more than 200 points that can be used for comparison including rings and freckles.

• The scans use a regular video camera and can be done from further away than a retinal scan.

Page 6: Ict  Security Measures

Retinal Scanning• Involves the scanning of retina and analysing the layer of blood vessels at

the back of the eye• Involves using the low intensity of light source and optical coupler and can

read the patterns at a great level of accuracy.• The accuracy is very good and the cost is fair.• Requires the user to remove glasses and place their eye close to the

device.

Voice Recognition• Compares a person’s live speech with their stored voice patterns.• Requires user to speak into a microphone.• What he speaks can be his password or access phrase.• Verification time is approximately 5 seconds. To prevent recorded voice

use, most recognition devices require the high and low frequencies of the sound to match.

Signature Verification System• Recognises the shape of your hand written signature as well

as measuring the pressure exerted and the motion used to write the signature.

• Uses special pen and a special tablet. • After pre-processing the signature, several features

extracted.• The authenticity of a writer is determined by comparing an

input signature to a stored reference set consisting of three signatures.

• The accuracy is fair and the cost involved is excellent

ConclusionConclusion

Authentication is very important to prevent Authentication is very important to prevent unauthorised access of a person’s data.unauthorised access of a person’s data.
