A content distribution is performed by a secure container including a content encrypted by a content key and container information set for a content transaction. The container information includes a person identification certificate identifiers list. Usage control status information including the list is generated and stored in a device during a secondary distribution among user devices after a primary distribution of the content. In the distribution among the user devices, identifying an identification certificate in reference to the list and performing a person authentication based on the identification certificate allows each of the user devices to use the transmitted content, when the authentication is affirmative.
