1. A hardware graphics processor to: modify, prior to encryption using electronic code book (ECB) encryption, 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 retains perceptual similarity to the bitmap of the image, and wherein the perceptual similarity is based on a determination that the bitmap and the noisy bitmap are perceptually correlated by at least one of a human eye or an optical character recognition (OCR) device; and encrypt the noisy bitmap using ECB encryption to create an encrypted image thereof, wherein the encrypted image does not retain perceptual similarity to the bitmap of the image and does not include a visually recognizable pattern from the image.
