Abstract
A method of biometric authentication includes receiving a biometric input from a user for authentication of the user to access a system. The method includes receiving a set of elements of a field and a random number from an authentication server via a network. The method further includes decoding the biometric input based on the set of elements to generate a polynomial. The method also includes generating a signature key based on the polynomial. The method includes signing the random number with the signature key. The method includes sending the signed random number to the authentication server. The method further includes restricting access to the system until the user is authenticated by the authentication server. The method also includes permitting access to the system in response to receiving an authentication message from the authentication server.
