Authentication apparatus and method for use in vehicle
First Claim
1. An authentication method for use in a vehicle comprises:
- identifying validity by use of identification information stored;
detecting an unauthorized use risk level predicted by a state of a vehicle;
changing an authentication level according to an identification result and the unauthorized use risk level at the time of processing a biometric authentication;
calculating a matching level between first biometric characteristic information of a vehicle passenger and second biometric characteristic information stored; and
comparing the matching level calculated and an authentication level to output an authentication result at the time of processing the biometric authentication.

2. An authentication apparatus for use in a vehicle comprises:
-
an identifying portion that identifies validity by use of identification information stored in a memory portion;
an unauthorized use risk level detecting portion that detects an unauthorized use risk level predicted by a state of a vehicle;
an authentication level changing portion that changes an authentication level according to an identification result of the identifying portion and the unauthorized use risk level detected by the unauthorized use risk level detecting portion at the time of processing a biometric authentication;
a matching level calculating portion that calculates a matching level between first biometric characteristic information of a vehicle passenger and second biometric characteristic information stored in the memory portion; and
a comparing portion that compares the matching level calculated by the matching level calculating portion and the authentication level to output an authentication result. - View Dependent Claims (3, 4, 5, 6, 7, 8)
