Abstract
A method and system are implemented for verifying connection status information associated with a specific display attachment location. Specifically, one embodiment of the present invention sets forth a method, which includes the steps of receiving a first signature representative of a first set of connection states tracked by a graphics subsystem associated with the display attachment location, authenticating whether the integrity of a content path including the display attachment location is maintained based on the first signature, and deciding whether to continue sending the content to the display attachment location so that requirements associated with protecting the content are satisfied.
Claims20
A method for handing display content through a display attachment location, the method comprises:
- receiving a first signature representative of a first set of connection states tracked by a graphics subsystem associated with the display attachment location;
- authenticating whether the integrity of a content path including the display attachment location is maintained based on the first signature;
- and
- deciding whether to continue sending the content to the display attachment location so that requirements associated with protecting the content are satisfied.
A computing device configured to enable a client graphics application to manage the handling of content through a display attachment location, the computing device comprising:
- a graphics subsystem configured to track a first set of connection states associated with the display attachment location and generate a first signature based on the first set of connection states;
- and
- a host processing unit configured to execute programming instructions of the client graphics application to:
- authenticate whether the integrity of a content path including the display attachment location is maintained based on the first signature received from the graphics subsystem;
- and
- decide whether to continue sending the content to the display attachment location based on the requirements associated with protecting the content and the first set of connection states.
A non-transitory computer-readable storage medium containing a sequence of instructions, which when executed by a host processing unit, causes the host processing unit to:
- receive a first signature representative of a first set of connection states tracked by a graphics subsystem associated with a display attachment location;
- authenticate whether the integrity of a content path including the display attachment location is maintained based on the first signature;
- and
- decide whether to continue sending the content to the display attachment location so that requirements associated with protecting the content are satisfied.
