摘要 |
A duplication/delivery center DDS records contents C11 and C12 on a recording medium M in accordance with requests from content providing apparatuses CP11 and CP12, duplicates the recording medium M, and delivers the recording medium M to users. When doing so, parts of the contents are encrypted. The content providing apparatuses CP11 and CP12 request a content control apparatus CC1 to control the contents on the recording media M. At the side of contents users, when a user sets a recording medium M in a video game console GM and tries to use a content that has been encrypted, the video game console GM requests, via a mobile packet communication network MPN, the content control apparatus CC1 to transmit a decryption key. The content control apparatus CC1 decides whether or not to transmit the decryption key based on the content of the request received from the content providing apparatus. |
