What is Biometrics?

Technique of studying physical characteristics
of a person such as:



fingerprints, voice, DNA, eyes, face, hand
Greek for life and measure
Science and technology of authentication

by measuring:


physiological features
behavioral features
Common Biometrics Methods







Fingerprinting
Voice Recognition
DNA Fingerprinting
Retinal Scanning
Iris Scanning
Face Recognition
Hand Geometry
Fingerprinting

Oldest successful method used


Most commonly used method for:



Early 1800s
Forensic evidence tool
May outperform DNA identification
Measure ridges and grooves

Minutiae-based technique


Correlation-based technique


Maps points
Gray-scale representation
others
Voice Recognition or Voice Print

the technology by which:

sounds, words or phrases
spoken by humans are:

converted into electrical signals




signals are transformed into coding
patterns
identified by a computer
Input commands
Differentiate a person’s voice
DNA Fingerprinting



Examine DNA pair sequence
Near perfect accuracy
Used for:


Forensic evidence
Heredity checking



Family
evolution
Future heath advances
Retinal Scanning

Scans retina of eye



1984- first time used
Uncomfortable but accurate




Blood vessels behind eye
Must be close to machine
Light in eye for 10-15 seconds
Must hold head still
Used in high security areas
Iris Scanning

Scans iris of eye



Takes picture of eye
1994- Algorithm developed, first used


Used in James Bond movie in 1980s
Easy to use



Unique patterns of colors, rings, specks, etc
Stand up to 2 feet away
Take a few seconds
Used by airports, prisons, banks
Face Recognition


Scan person’s face
Measures certain features:




Jaw, noise, space between eyes
Not very accurate
Very expensive
Used with other biometric
devices
Hand Geometry


Analysis of a hand
Uses metal surface




Small pegs
Somewhat accurate
Every hand is not unique
Use with small database

Small corporation
Controversy

Threat to privacy


Fear of new technology


Scanning face, eyes, fingerprints in public
Scenarios such as placing chip under skin
May not be as accurate as thought


Criminals using fake eyes, burning fingerprints, etc
Mistakes could be made


Place innocent people in jail
DNA issues


Asked about:


Biometrics used
His thoughts
My Thoughts



Great possibilities
More in future
Make life easier




Less passwords
No keys
Safer future
I do not think chips will be implanted in
people
Conclusion






Biometric methods used for centuries
Most accurate form of identification
Many methods used
Great for crime fighting
Great for security
Promising future
