"function creep" - introduction of a technology for a specific purpose
which then unintentionally migrates into another area of use (potentially
negative)
"invasive" vs. "non-invasive" "contact" vs.
"non-contact" "cooperative" vs. "non-cooperative"
Fingerprint features: minutia, ridge, valley, ending, bifurcation, arch, loop, whorl
Fingerprint matching: local versus global techniques,
minutia matching versus correlation matching
latent fingerprint
receiver operating characteristic curve
false accept rate, false reject rate
multi-modal biometrics
sample size, population
Five major biometric techniques:
Fingerprint
Hand Geometry
Face Recognition
Iris Pattern
Voice Recognition
verification/authentication vs. recognition/identification one-to-one
match (easier) vs. one-to-many match (much more difficult)
