Zusammenfassung:	PROBLEM TO BE SOLVED: To allow a registered user to be correctly authenticated based on a musical piece corresponding to the user even in the case that parameters of the musical piece has been changed.SOLUTION: Even if parameters of a musical piece indicated by musical piece data made to correspond to a user have been changed, respective parameters of the musical piece indicated by musical piece data made to correspond to the user are restored before user authentication based on the musical piece played back from a terminal device 2 (s530). As a result, the musical piece corresponding to the user is compared with the same musical piece having parameters not changed when being played back from the terminal device 2, whereby the user can be correctly authenticated.
