1. Biometrics
Biometrics refers primarily to the measurement of physiological and behavioral characteristics to automatically identify people.

2. Biometrics
Biometrics is the study of automated methods for uniquely recognizing humans based upon one or more intrinsic physical or behavioral traits
biometric authentication refers to technologies for measuring and analyzing human physical and behavioral characteristics for authentication purposes.

3. Biometrics Physiological characteristics Behavioral characteristics
face
fingerprint

gait

4. Biometrics Issues and Concerns
Technology has the potential to do great things.
It also brings with it the potential to do harm.
Are concerns surrounding biometric use real or imagined?
Do our concerns prevent us from seeing the vast potential of the new technologies developed using biometrics

5. Biometrics Issues and Concerns: This could happen -
DNA is planted at the scene of the crime
Assume another's identity by using the person’s biometrics or simulating their biometrics. In this way, impersonate them without arousing suspicion
Fool a fingerprint detector by using a piece of sticky tape with an authentic fingerprint on it
Fool an iris recognition camera by showing a photo of another’s iris
Hack into the interface between a biometric device and the host system, so that a "fail" message gets converted to a "pass".

6. Biometrics Issues and Concerns - More difficult to forge
- More problematic when lost or stolen

7. Biometrics Identity theft Biometrics can confuse the solution
Credit card theft is a significant problem for the individual involved.
BUT, If a person’s fingerprints are stolen, the damage could be irreversible.
Are biometric technologies being used without adequate safeguards?

8. Biometrics
Privacy
Biometrics are often are touted as a way to reduce crime. Yet, privacy advocates fear biometrics may be used to decrease personal liberties of law abiding citizens.
Developments in digital video, infrared, x-ray, wireless, global positioning satellite systems, image scanning, voice recognition, DNA, and brain wave fingerprinting provide government with new ways to "search" individuals and collect vast databases of information on law-abiding members of the public.

9. Biometrics Who is watching the watchers?
The 4th Amendment guarantees free speech and a right to privacy. Do biometrics strip away these rights?
If everyone is biometrically “searched” at a concert or sporting event and compared with a database of known terrorists we “may” be safer, but have we lost something in exchange?

10. Biometrics Sociological concerns
As technology advances, more and more private companies and public utilities will use biometrics for safe, accurate identification.
Is this the direction we want technology to go?
Are there physical dangers:
Are retinal scans safe?
How accurate are the devices in question?
If DNA is found at the site of an investigation, who knows when I was there?
