Simultaneous compression and encryption of color video images

We study theoretically a simultaneous compression and encryption method which is optically implementable and well adapted to color images. Remarkably, we also show that an optimized version of this method can be used to process images from video sequences which are treated as multiple images with taking care of temporal redundancy. The major strength of the method is in its generality and robustness against various known-plaintext attacks making this algorithm appealing for color video images.
