摘要： Digital rights management method and system for items having usage rights. A first activation device defines a first trust zone. A first license device associated with the first trust zone generates an open license having usage rights associated with a first item. A second activation device defines a second trust zone and is adapted to issue a software package that enforces usage rights. A user device associated with the second trust zone is adapted to receive the software package from the second activation device, to receive the open license associated with the first item, and to use the first item in accordance with the open license. In addition, a method is provided for enforcing a license granting usage rights associated with a protected item, and for classifying a license, the license being an open license or a closed license.
