Abstract
An authentication system prevents leakage of a key-reading speech during user authentication based on the key-reading speech of a user reading an authentication key. For each user ID, a storage stores a voiceprint of a user in association with a recorded sound including speech spoken previously by the user. A specifier specifies the user ID of a user attempting to receive authorization. An outputter outputs a masking sound that includes the recorded sound recorded in association with the specified user ID. An acquirer acquires a key-reading speech of the user reading the authentication key and the output masking sound. A remover acquires a second sound by removing the masking sound from the acquired first sound. A determiner determines whether the user has authority pertaining to the specified user ID based on the acquired second sound.
