Methods and systems for protecting data that is intended for use and
processed on video or graphics cards are described. In one embodiment, a
system comprises a graphics processor unit (GPU) for processing data that
is to be rendered on a monitor. Memory is operably associated with the
graphics processor unit for holding data that is to be or has been
processed by the GPU. A display converter converts digital data to
signals for use in rendering the data on the monitor, and a memory
controller is configured to receive encrypted data and decrypt the
encrypted data into protected regions of the memory.
