Claim 8:
9. A method for authenticating a user, comprising:
providing an authentication challenge to the user, the authentication challenge configured to authenticate the user against a biometric model tailored to the user;
detecting, from one or more sensors, a response to the authentication challenge;
determining, based on the biometric model, that the detected response matches an expected response within a degree of accuracy;
in response to detecting a biometric change of the user, providing one or more additional challenges to the user;
modifying the biometric model based on one or more additional responses to the one or more additional challenges;
transmitting, via a network interface component, an indication of a successful authentication in response to determining that the detected response matches the expected response within the degree of accuracy; and
receiving access to a service based on the detected response matching the expected response within the degree of accuracy.
