The user authentication system includes a profile generation unit 14 at the side of a user terminal 10, and a profile storage unit 33 and a confirmation/replication verification unit 31 at the side of an authentication verification device 30. When authentication processing is executed in the user terminal 10, the profile generation unit 14 aggregates input biometric information, registered biometric information, and information which duplicates collation processing contents, and sets a profile S12 being an aggregation of data. The profile storage unit 33 stores the profile S12 at the outside of the user terminal 10 with identification information of authentication processing. The confirmation/replication verification unit 31 confirms the stored contents, and replicates collation processing. Accordingly, when verification is necessary, the validity of authentication processing in the user terminal 10 is verified, and a service provider device 20 is notified of this. Accordingly, there is provided a system which can verify the validity of the authentication processing performed in the user terminal when the service provider side needs the validity.
