Abstract
Abstract A system for offering a large amount of information such as images and musics safely, accurately, effectively and at low cost is provided. In the system, a CD-ROM 42 is offered from an information offerer to an user. An user ID is transmitted from the user to the information offerer through a communication interface section 36. When the user ID is determined to be an ID of a legitimate user by the information offerer, access authorizing information which authorizes the user to access to and read information in the CD-ROM 42 is transmitted from the information offerer to the user. Thereby, a CD-ROM reader 31 can read the predetermined information from the CD-ROM 42.
