Abstract
Systems and methods are provided to enable secure remote activation and/or unlocking of content or other media assets protected using one or more copy protection mechanisms or techniques. Existing trusted processor architectures used by electronic devices (e.g., HD-DVD or Blu-Ray optical disc readers) can be used to allow remote activation and/or unlocking of protected content. An authorization server is configured to identify the specific copy of the protected content or other media assets at the device from the request, and determine the correct correlation between the request and information that enables the device to initiate playback of the protected content. Accordingly, the authorization server maintains secret or private on the authorization server the information that can be used by other parties to obtain a correlation between the request and any response received from the authorization server that enable the device to initiate playback of the protected content.
