Abstract
An apparatus and method for preserving image privacy when manipulated by cloud services includes middleware for receiving an original image, splitting the original image into two sub-images, where the RGB pixel values of the sub-images have a bit value that is less than RGB pixel values of the original image. The sub-images are encrypted by adding a keystream to the RGB pixel values of the sub-images. The sub-image data is transmitted to a cloud service such as a social network or photo-sharing site, which manipulate the images by resizing, cropping, filtering, or the like. The sub-image data is received by the middleware and is successfully decrypted irrespective of the manipulations performed by the cloud services. In an alternative embodiment, the blocks of the original image are permutated when encrypted, and then reverse-permutated when decrypted.
