The Wonderful world of Biometrics Welcome to

www.voicetrustgroup.com © VOICETRUST eServices - strictly confidential 3

Biometrics is, in the simplest definition, something you are.

It is a physical characteristic unique to each individual.

Has been in use to identify individuals as early as the ancient Egypt.

Today, it is becoming more and more popular to identify and authenticate

people for accessing secure areas and systems.

What is Biometrics ?

Voice Biometrics

While pins and passwords will become a relic of the past, voice is emerging as a viable authentication method for online and mobile transactions. Known as ‘Voice Biometrics’ or ‘VoicePrint’, this unique method will become the preferred way of conducting safe and secure financial transactions.

A voice print is as distinctive as a finger print or palm print, thereby separating one individual from another. As a unique, unmistakable authentication system, Voice Biometrics will prevent the risk of unauthorized access, duplication and fraudulent access to business applications.

www.voicetrustgroup.com © VOICETRUST eServices - strictly confidential 42

Retinal Recognition

Capture the unique patterns of blood vessels at the back of the eyeball by casting a beam of low-energy infrared light into a person’s eye as they look through a scanner's eyepiece

Iris

www.voicetrustgroup.com © VOICETRUST eServices - strictly confidential 43

Retina Biometrics

Advantages: – Retinal patterns are highly distinctive traits – Every eye has its own totally unique pattern

of blood vessels (the eyes of identical twins are distinct)

– Each pattern normally remains stable over a person’s lifetime (can be affected by disease)

– Considered one of the best biometric for performance/accuracy

– Used for access control in very high security environments

www.voicetrustgroup.com © VOICETRUST eServices - strictly confidential 44

Retina Biometrics

Disadvantages: – Intrusive and inconvenient – Ineffective for the blind and those with

cataracts – Affected by disease such as glaucoma,

diabetes, high blood pressure, and autoimmune deficiency syndrome

– Capture is difficult. (An individual must place their eye very close to the lens of the retina-scan device and remain perfectly still while focusing on a revolving light)

– Any movement can interfere with the process. (Enrollment can easily take more than a minute)

www.voicetrustgroup.com © VOICETRUST eServices - strictly confidential 45

Palmprint Biometrics

Similar to fingerprint systems

Palmprint systems use ridges, principal lines and wrinkles on the surface of the palm

Advantages:

– Larger surface provides for a greater number of possible features for extraction

Disadvantages:

– Palmprint scanners are usually bulkier and more expensive than fingerprint scanners

www.voicetrustgroup.com © VOICETRUST eServices - strictly confidential 46

Uniqueness of the Human Voice

Voice biometrics differs from all other forms of biometrics as voice is a complex function created and generated by at least 14 different physical organs.

FIG: PHYSICAL ORGANS RESPONSIBLE FOR CREATING UNIQUE CHARACTERISTIC PARAMETERS & DATAPOINTS

In a 4-second voice sample, there are over 200,000 data points with 1,200 characteristic parameters

The spoken phrases are rich in vowels. VOICETRUST has patented the selection of such phrases according to their phonetic suitability.

www.voicetrustgroup.com © VOICETRUST eServices - strictly confidential 55

Using Voice Biometrics mainly consists of the following two processes. 1. Enrollment / Registration

a. This is the process of capturing voice samples from the user through a Telephone or a mobile device and feeding this data to the Voice biometric engine.

b. The Voice biometric engine uses these samples to generate what is known as a unique “Voice-Model” or a “Voice-Print” for each individual.

2. Verification / Authentication Once the user’s Voice-Print is already available in the system, the user can gain remote

access to various services by going though a Voice verification process.

a. Here, the user is challenged by the Voice Verifier to say or repeat some words/sentences using a Telephone or a Mobile device.

b. The Voice Verifier compares the user’s speech against the stored “Voice-Print” and based on the results of the comparison, either provides or rejects access to the user.
