摘要
System for protecting both copyrights of digital content which producers own and fair-use rights of digital content which consumers own at the same time. In addition to an authentication management unit, a copyrights management unit and a crypt key management unit, also a fair-use rights management unit is established in a key center. For copyrights protection, the authentication management unit, the copyrights management unit and the crypt key management unit are connected to each other to work. For fair-use rights protection, the authentication management unit, the copyrights management unit, the fair-use rights management unit and the crypt key management unit are connected to each other to work. The fair-use rights management unit confirms fair-use and permits to provide a consumer with a crypt key for re-decrypting according to the fair-use.
