The server includes at least a fingerprint-feature comparing unit and a specified content distributor. The fingerprint-feature comparing unit accesses a registered user information table in which personal information regarding a user, a user identification, and fingerprint feature information, and reads therefrom fingerprint feature information of a person who requests a content distribution so as to compare the fingerprint feature information with fingerprint feature information of the person inputted from the user terminal. The specific content distributor distributes a requested content to the user terminal only when match is made as a result of comparison.
