APPARATUS AND METHOD FOR HARDWARE-BASED SECURE DATA PROCESSING USING BUFFER MEMORY ADDRESS RANGE RULES Russian patent published in 2016 - IPC G06F12/14 G06F21/71 

FIELD: information technology.

SUBSTANCE: processor for processing a data stream from a plurality of media content sources for a display device comprises a security unit which determines if output data to be recorded from a video codec into buffer memory are based on input data from at least one secure cell associated with a secure buffer memory address range, and in response to the determination: i) allows the recording of output data into one or more secure buffer memory cells, wherein the secure cells are associated with a secure buffer memory address range; and ii) blocks the recording of output data into one or more non-secure buffer memory cells. The non-secure buffer memory cells are associated with a non-secure buffer memory address range.

EFFECT: secure data processing.
