System and method for data encryption

A system for processing encrypted image data, comprising:

• a first storage area to store encrypted input image data corresponding to at least a portion of a video frame;
• an encryption map containing data for reversibly decrypting the encrypted input image data;
• and
• a graphics processor to process the encryption map and the encoded input image data to thereby generate decrypted output image data.

A method for processing image data for display on a video display device, comprising:

• storing input image data corresponding to at least a portion of a video frame;
• generating an encryption map to reversibly encrypt the input image data;
• and
• processing the input image data and the encryption map to thereby generate encrypted output image data.

A computer-readable media that causes a computer to process image data for display on a video display device by performing the steps of:

• storing input image data corresponding to at least a portion of a video frame;
• generating an encryption map to reversibly encrypt the input image data;
• and
• processing the input image data and the encryption map to thereby generate encrypted output image data.
