Secure Exclaves

A computing device, comprising:

• a user interface;
• and
• user interface pipeline circuitry coupled to the user interface and configured to:
• process a set of data to produce an output for the user interface of the computing device;
• extract, from the output prior to presenting the output via the user interface, data corresponding to where an indicator is inserted into the output to indicate that a component of the computing device has been activated;
• and
• provide the extracted data for analysis to determine whether the indicator remains inserted into the output.

A method, comprising:

• processing, by user interface pipeline circuitry of a computing device, a set of data received from a source to produce an output for a user interface of the computing device;
• prior to presenting the output via the user interface:
• inserting, by a first stage of the user interface pipeline circuitry into the output, an indicator of a component being activated;
• and
• extracting, by a second stage of the user interface pipeline circuitry from the output, data corresponding to where the indicator is inserted to confirm that indicator remains inserted.
