摘要： A computer implemented method and apparatus for avoiding license storming during an unplanned regional blackout. The method comprises generating a leaf license for each geographic region of a plurality of geographic regions in a broadcast area, wherein each leaf license includes a first content encryption key for decrypting media content associated with the leaf license, and where each leaf license is bound to a root license for each geographic region in the plurality of geographic regions; and generating, in response to a blackout event, a new leaf license for each geographic region of the plurality of geographic regions that are located outside of a blackout area, wherein each new leaf license includes a second content encryption key different from the first content encryption key for decrypting protected media content, and wherein each new leaf license remains bound to the root license for each geographic region in the plurality of geographic regions.

摘要： A secure location system is described herein that leverages location-based services and hardware to make access decisions. Many mobile computers have location devices, such as GPS. They also have a trusted platform module (TPM) or other security device. Currently GPS location data is made directly accessible to untrusted application code using a simple protocol. The secure location system provides a secure mechanism whereby the GPS location of a computer at a specific time can be certified by the operating system kernel and TPM. The secure location system logs user activity with a label indicating the geographic location of the computing device at the time of the activity. The secure location system can provide a difficult to forge, time-stamped location through a combination of kernel-mode GPS access and TPM security hardware. Thus, the secure location system incorporates secure location information into authorization and other operating system decisions.
