Abstract
A method and apparatus for authenticating a user are provided. An authentication apparatus includes a data set generator configured to generate an authentication data set by extracting waveforms from a biosignal of a user, a similarity calculator configured to match each of the extracted waveforms to registered waveforms included in a registration data set, and calculate a similarity between each of the extracted waveforms and the registered waveforms, and an auxiliary similarity calculator configured to extract a representative authentication waveform indicating a representative waveform of the extracted waveforms and a representative registration waveform indicating a representative waveform of the registered waveforms, and calculate a similarity between the representative authentication waveform and the representative registration waveform.
