Introduction


What is biometrics?


Types of biometrics


Controversy


Interview


My thoughts


Conclusion

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


Early 1800s


Most commonly used method for:


Forensic evidence tool


May outperform DNA identification


Measure ridges and grooves


Minutiae
-
based technique


Maps points


Correlation
-
based technique


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


Blood vessels behind eye


1984
-

first time used


Uncomfortable but accurate


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


Unique patterns of colors, rings, specks, etc


Takes picture of eye


1994
-

Algorithm developed, first used


Used in James Bond
movie

in 1980s


Easy to use


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


Scanning face, eyes, fingerprints in public


Fear of new technology


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


evolution

Interview


Richard Ortiz


Security Specialist


Moody Air Force Base


2 years


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
