Abstract
An access system in one embodiment that first determines that someone has correct credentials by using a non-biometric authentication method such as typing in a password, presenting a Smart card containing a cryptographic secret, or having a valid digital signature. Once the credentials are authenticated, then the user must take at least two biometric tests, which can be chosen randomly. In one approach, the biometric tests need only check a template generated from the user who desires access with the stored templates matching the holder of the credentials authenticated by the non-biometric test. Access desirably will be allowed when both biometric tests are passed.
