Passwords Are Not Enough!

� Passwords are easily changed

� Passwords are difficult for people to manage

� Passwords are easily cracked

Can we rely on passwords to protect our valuabledigital data and communications?

Strong authentication means using two or more

authentication methods

Biometrics

Authentication using human identifying factors� Fingerprints

� Well accepted methodology� Long-used in law enforcement

� Hand prints� More complete picture than fingerprint

� Retina patterns� Unique but difficult and invasive� Requires a powerful scan

� Iris patterns� Not so unique (but somewhat so)

� Voice recognition� Can be fooled by recording someone·s voice

� Face recognition� Still difficult today and requires human intervention

Fingerprints ² A Deeper Study

� To understand the ease of biometrics, we will studyfingerprint authentication in greater detail

� Fingerprint authentication is secure if we can besure that there is a person standing behind thefingerprint

Biometric measures - Proves to be

beneficial

y Keys and passwords only seems to be beneficial which areactually not.

y Keys, passwords etc can be stolen, copied, lost, forgotten ² fingerprints, eyes cannot.

y Biometric ID ensures that a person requesting access is actuallythe person who was granted access

One-Time Passwords ² Security Factors

� Less number of attacks± Stealing one-time passwords is not an easy task (need

access to device) and provides very limited damage

�

Multiple factors of authentication± Yes (can require PIN as well as one-time password)

� Protection from phishing attacks

± No direct login, but if it does then damage is limitedto a single access
