Image scrambling technology can be used as an encryption algorithm for image information, among which Arnold transform is widely used in image scrambling algorithms. Since Arnold transform can only be directly applied to square images, this paper combines Arnold transform and chaotic logistic mapping to propose an algorithm for scrambling non-square digital images. By discussing the security performance of the algorithm, it is proved that this method has good practicality.
