Ann: Proof of concept achieved for security biometric technology, page-18

Here you go Phantom off the nxr preso........lol easier to give you the info than listen to the ranting!
Face– easy to use; least accurate /
reliable
 Vein – emerging technology; variable
results (poor in this study); body hair,
tattoos present as challenges
 Fingerprint – easy to use; consumer
technologies susceptible to fraud, prints
can wear out, psoriasis and other skin
conditions can yield unreliable results
 Voice – Reliable but subject to a number
of factors including anxiety, health,
stress, speech rate and volume as well
as background noise; challenge /
response deployment required to prevent
replay attacks
 Iris – high level of accuracy; enrolment
failure with people with dark irises, issues
for users affected by drugs / alcohol
