Abstract

Embodiments of the present invention pertain to determining whether a digital rights management system's native license is valid. According to one embodiment, a value of a decision indicator is accessed at a digital rights management system. The decision indicator is set by a trusted entity other than the digital rights management system because the digital rights management system does not have sufficient information to determine how to set the decision indicator. The value of the decision indicator is used at the decision rights management system to determine whether the native license associated with the digital rights management system is valid.
