Abstract
A content use management system includes a content-providing system and a content-using device. The content-providing system includes a providing unit that provides, to the content-using device, digital content having content identification information corresponding to user-side-specific information specific to the content-using device or a user of the content-using device, and a primary distribution destination field. The content-using device includes a first control unit that, when receiving an instruction for using digital content from a user, allows use of the digital content when content identification information included in the digital content corresponds to user-side specific information specific to the content-using device or a user of the content-using device, and executes a control process in accordance with a value of the primary distribution destination field of the digital content when the content identification information included in the digital content does not correspond to the user-side-specific information.
