Method for biometric-based authentication in wireless communication for access control

A system for biometric authentication based on communication between a portable electronic device and a security authenticator, said portable electronic device comprising any of:

• simplex, duplex, or tokenized modes of communications, said system comprising:
• a stimulus which requests a biometric template from said portable device;
• a biometric-reader which wirelessly receives said requested biometric template from said portable device;
• a biometric measurer which measures a user's biometric profile via a biometric reader, wherein
• said biometric reader located within said security authenticator if said biometric authentication is based on said simplex connections, else
• said biometric reader located within said portable device if said biometric authentication is based on duplex or tokenized connection;
• a biometric comparator which compares said wirelessly received biometric template with said measured biometric profile,
• an output-generator which generates an output based on said compared biometrics, wherein said output is
• an authentication token if said compared biometrics are identical and said biometric authentication is based on said duplex connection, else
• an authentication successful message if said compared biometrics are identical, and said biometric authentication is based on said simplex connection, else
• an authentication failure message if said compared biometrics do not match;
• an authentication validator which maintains the validity of said authentication token for a predetermined period of time based on a threshold or criteria test;
• and
• a token terminator which terminates said authentication token upon failure of threshold or criteria test.

A method for biometric authentication based on duplex communication between a portable electronic device and a system, said method as implemented in said portable electronic device comprising:

• receiving a challenge from said system;
• retrieving a biometric template from said portable device;
• measuring a user's biometric profile via a biometric measurer located within said portable device;
• comparing said retrieved biometric template with said measured biometric profile, and
• generating an output based on said compared biometrics, wherein said output is
• an authentication token and an authentication successful message if said compared biometrics are identical, said authentication successful message forwarded to said system issuing said challenge and said token stored locally in said portable electronic device, else
• an authentication failure message if said compared biometrics do not match.

A portable electronic device performing biometric authentication based on duplex communication with a system, said portable electronic device comprising:

• a biometric measurer which measures a user's biometric profile via a biometric reader located within said portable device;
• a biometric comparator which compares said measured biometric profile with a biometric template which is stored within said portable device;
• an output-generator which generates an output based on said compared biometrics, wherein said output is
• an authentication token and authentication successful message if said compared biometrics are identical said authentication successful message forwarded to said system and said token stored locally in said portable electronic device, else
• an authentication failure message if said compared biometrics do not match;
• an authentication validator which maintains the validity of said authentication token for a predetermined period of time based on a threshold or criteria test, and
• a token terminator which terminates said authentication token upon failure of threshold or criteria test.
