Abstract
An authentication method executed by a computer includes: receiving input data which is a target of authentication; specifying registration data, from among a plurality of registration data stored in a storage device, having a second feature value within a threshold value relative to a first feature value of the input data, the first feature value representing a distance between the input data and a reference, the second feature value representing another distance between the registration data and the reference, and the threshold value being used when a determination as to whether the authentication has been successfully performed; and executing a process of comparing the registration data with the input data.
