[image encryption] Based on matlab GUI orthogonal Latin square + two-dimensional Arnold scrambling image encryption [including Matlab source code 813]

1, Introduction 1 purpose of digital image scrambling So far, the more mature information hiding algorithms basically take the image as the carrier. Image scrambling, as the name suggests, is to disrupt the image and hide the real content of the original image. Digital image scrambling is similar to the idea of information file encryption. It ...
