Overview• The problem• What are biometrics?

– What are the different types?• Short video of a system with a fingerprinting

device.• Identifying the Individual

– How it Works• Advancing Technology• Conclusion

Problem• Systems today are not very well

secured since they are normally based on passwords, and other “known” data.

• Potential Solutions:– Biometrics– Two-Factor Authentication

• Using both knowledge based authentication with biometrics.

What are Biometrics• Definition:

The use of physiological, behavioral, and morphological characteristics that can be examined and quantified.

• The advantages– Increases the level of security on systems– Minimizes the usage of Passwords, SSN, and other knowledge

based data.

• The disadvantages– Costly– May fail when trying to identify an individual and

falsely deny them access to a system.

What are Biometrics (cont.)• Different Types:

– Physical Trait Biometrics• Fingerprinting• Iris/Retina Scanning• Hand Scanning

– Behavioral Trait Biometrics• Keystroke Pattern devices• Signature devices• Voice Recognition

Example• Biometrics Video

Identifying the Individual• How it works:

1. Use the right device to measure a particular trait to create a biometric.

2. Read the personal trait of the individual .3. Feature Extraction

• Identify the distinctive features associated with the biometric.

4. Create the Biometric Signature.5. Compare and Match the data against the

database stored in the system.

Advancing Technology• The systems are not well secured

with just passwords and important personal identification numbers.– Thanks to hackers and frauds.

• Soon enough the cost to owning biometric devices will decrease heavily with many successful attempts and popularity.
