Laptop security using Biometric Measures

Improved management of user passwords

Digital signing of transactions

Secure PCs and laptops



Leaking information

y Stealing millions of data from veteran·s laptop(2/04)

y Confidential Data on laptop stolen from employee·s home(5/05)

y Veterans· company data

y Social Security numbers

y Bank account details

y CardSystems exposes data of 40 million cards (2006)

y

Data on 70,000 cards downloaded from ftp serverThese are attacks on privacy (confidentiality, anonymity)



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



What Is Strong Authentication?

What you know What you have

Strong authentication means using two or more

authentication methods

What you are

Authentication ² the three what·s

Biometrics???



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



Fingerprint Recognition:

Sensors (II)

E-Field Sensor[FingerLoc� by Authentec]

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



Usefulness of biometric measures



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
