1. A processor implemented authentication method, comprising:
obtaining a second enrolled feature, the second enrolled feature having been generated by transforming a first enrolled feature to the second enrolled feature, the first enrolled feature having been extracted from a first input data by a first feature extractor comprising a first neural network;
determining an input feature by extracting a feature from a second input data with a second feature extractor comprising a second neural network different from the first neural network; and
performing an authentication based on the second enrolled feature and the input feature.
