Method and apparatus for taking action based on coded graphical object in video content

1. A method for taking a predetermined action based on a coded graphical object in video content for display by a computer device, comprising:

generating, by a host subsystem of the computer device, the video content;

receiving, by a secure subsystem of the computer device that is separate from the host subsystem, the video content over a bus of the computer device; and

determining, by the secure subsystem and transparently to the host subsystem, whether the coded graphical object is present in the video content,

wherein receiving includes the secure subsystem presenting itself as a graphics endpoint to the host subsystem, and

wherein the graphics endpoint comprises a PCIe connected graphics adapter.

2. A method according to claim 1 , wherein the coded graphical object is a barcode.

3. A method according to claim 1 , wherein the coded graphical object is a QR code.

4. A method according to claim 1 , wherein the predetermined action includes performing a monitoring function.

5. A method according to claim 1 , wherein the predetermined action includes automatically providing credentials to a web service.

6. A method according to claim 1 , wherein determining includes:

storing the video content in a frame buffer of the secure subsystem;

causing the video content to be displayed on a display device from the frame buffer; and

performing a pattern recognition technique on data in the frame buffer to detect the coded graphical object.

7. A method according to claim 1 , wherein determining includes:

detecting a first graphical object in the video content;

comparing the first graphical object to a predetermined type of graphical object; and

if the first graphical object is the predetermined type of graphical object, identifying the coded graphical object in an action table.
