A computer-implemented secure and standalone biometric authentication captures, at an enrollment agent, a biometric sample from a person into a biometric template. At the enrollment agent, the biometric template is irreversibly converted into a converted biometric template using a pre-determined irreversible conversion function. The converted biometric template is then stored in an electronic device of the person. At an authentication agent, the person is authenticated by (1) capturing a new biometric sample from the person and irreversibly converting, using the same irreversible conversion function during enrollment, the new live biometric sample into a converted live biometric template, (2) obtaining the converted biometric template from the electronic device, and (3) analyzing the converted biometric templates to determine if they belong to the same person. A secure and standalone biometric authentication system is also described. |
