Abstract:
Computer systems and environments implemented herein permit a local machine increased participation in authorizing access to protected content. An operating system attests to a computing environment at a corresponding computer system. If the computing environment is one permitted to access protected content, the operating system is permitted to regulate further (e.g., application) access to protected content in accordance with a procreation policy. As such, authorization decisions are partially distributed, easing the resource burden on a content protection server. Accordingly, this computing environment can facilitate more robust and efficient authorization decisions when access to protected content is requested.
