Document Type and Number:
Japanese Patent JP7412445
Kind Code:
B2
Abstract:
[Problem] To provide a novel method capable of finely controlling access authorization to content stored in a removable medium. [Solution] This content duplication device 1 duplicates content by encrypting the content to be distributed and writing the encrypted result in a removable medium 2 such as an SD card. This access control device 3, which is a receiver of the removable medium 2, performs a setup process and controls access authorization to content stored in the removable medium 2. Here, the access authorization to the content stored in the removable medium 2 is not directly controlled by the content duplication device 1, but is controlled by a content control device 3 on the basis of content designated by the content duplication device 1. In addition, the access authorization control for the content is flexibly performed by changing the content designated by the content duplication device 1.
