1. A graphics processor to modify pixel values for at least a subset of pixels in a bitmap of an image to create a noisy bitmap of the image, wherein the noisy bitmap of the image provides randomness in pixels but is visually similar to the bitmap of the image; and encrypt the noisy bitmap using electronic code book (ECB) encryption to create an encrypted image thereof, wherein the encrypted image does not include visually recognizable patterns from the image as would be the case if the bitmap was encrypted using ECB.
