ABSTRACT:
An information distribution system includes a portable electronic device, and an information management apparatus for storing both right information and information which corresponds to the portable electronic device and which indicates to whom a right belongs. By using a code unique to the portable electronic device to encrypt concert information as the right information to be offline-providable form, and providing a ticket code generated by the encryption so that it passes through an offline channel at least once, the distribution to each user of the encrypted information can be simplified.
