1. A method of authentication comprising: capturing palm biometric data with a device from an individual, transmitting the captured biometric data to a biometric authentication system, and generating an authentication biometric template from the captured biometric data with the biometric authentication system; conducting a plurality of verification matching transactions between the authentication biometric template and enrollment biometric templates stored in the biometric authentication system, and between the authentication biometric template and imposter biometric templates stored in the biometric authentication system, wherein the enrollment biometric templates and imposter templates are associated with the individual in the biometric authentication system, and the imposter biometric templates are generated from biometric data obtained from known imposters; updating a genuine matching score distribution with at least one genuine matching score generated during said conducting operation; updating an imposter matching score distribution with at least one imposter matching score generated during said conducting operation; calculating a maximum genuine matching score and a minimum imposter matching score; determining whether the minimum imposter matching score is greater than the maximum genuine matching score; and confirming an identity of the individual when the minimum imposter matching score is greater than the maximum genuine matching score.
