Abstract

A management device (105a) manages duplication of information from an original recording medium (101a) to a duplicate recording medium (102a). The management device (105a) is provided with a transmission / reception unit (701a) which receives an original medium identifier for identifying the original recording medium (101a) from a duplication device (104a) and transmits permission information indicating permission to duplicate the information to the duplication device (104a), and a control unit (708a) which, on the basis of the received original medium identifier and an original medium identifier for identifying a registered original recording medium, determines whether or not the duplication of the information recorded on the original recording medium is permitted, and when determining that the duplication is permitted, permits the transmission of the permission information.

Description

technical field [0001] The present invention relates to a technique for managing duplication of information from an original recording medium on which information is recorded to a duplicate recording medium.
