authorized to enter the facility?”, “Is this individual entitled to access the privileged informa-

organizations in both public and private sectors. Because biometric identifiers cannot be easily
misplaced, forged, or shared, they are considered more reliable for person recognition than
traditional token- (., keys) or knowledge- (., password) based methods. Biometric
recognition can provide better security, higher efficiency, and increased user convenience. It is
for these reasons that biometric systems are being either increasingly deployed or evaluated in
