At many security checkpoints where biometrics are used, only one protocol is employed, such as a fingerprint reader, a hand-scanner, or facial recognition. Other checkpoints use several biometric checkpoint protocols in tandem to add a layer of security.
Complete an internet search for vendors of biometric products. Find one vendor with a product designed to examine several characteristics [i.e., facial recognition, hand scanner (incorporates hand pattern, fingerprint reader), retina scan, and signature recognition].
Discuss the vendor you selected along with answers to the following questions:
Which characteristics would be more acceptable to users?
Which would be preferred by security administrators?
