An object-based integrity verification method for detecting hazardously misleading information contained in an output image of a graphics processing unit comprises steps of: identifying a plurality of safety-critical graphic objects in the output image; assigning each safety-critical graphic object an object ID code; creating an object verification database; rendering a monochrome reference ID code image using object ID code as its color component; verifying the location, shape and color information for each safety-critical graphic object, and tracking the visibility and overlaying property between safety-critical graphic objects using the monochrome reference ID code image; detecting and evaluating failure condition; and annunciating the failure condition with proper warning level and appropriate corrective action.
