Abstract

We present a biometric authentication algorithm with 3 possible outputs: accept the claimed identity, reject the claimed identity, and no answer. The algorithm is based on the model of non–stationary random processes and transformations of realizations of the processes to q-ary vectors whose components are uniformly distributed over the set { 0,...,q − 1 }, where q is fixed. An application of the algorithm brings the false acceptance and the false rejection rates that do not depend on the probability distribution over the templates space and exponentially decrease with the number of independent biometric parameters available to an observer.
