BIOMETRICS: FACIAL RECOGNITION TECHNOLOGY
[attachment=26234]
WHAT IS BIOMETRICS?
BIOMETRICS – any automatically measurable, robust and distinctive physical characteristic or personal trait that can be used to identify an individual or verify the claimed identity of an individual.
TYPES OF BIOMETRICS
Iris Scanning
-measures the iris patter in the colored part of the eye
Retinal Scan
-measures the blood vessel patterns in the back of the eye
FACIAL RECOGNITION
Facial recognition is a form of computer vision that uses faces to attempt to identify a person or verify a person’s claimed identity. Regardless of specific method used, the facial recognition is accomplished in a five step process.
FIVE STEP PROCESS
COMPARISON
-the face print created by the software is compared to all face prints the system has stored in its database.
MATCH OR NO MATCH
-software decides whether or not any comparisons from step 4 are close enough to declare a possible match
CONTROVERSY
THE BORDER EXCEPTION
-the fourth amendment recognizes the longstanding right of the sovereign to protect itself by stopping and examining persons and property crossing into this country
