A new image scrambling method through folding transform

A new image scrambling method is proposed in this paper. It is based on a folding transform with folding matrix which is orthogonal and enables us to fold images either up-down or left-right. When an image is folded through this way repeatedly, it becomes scrambled. The experimental results demonstr...

Summary:A new image scrambling method is proposed in this paper. It is based on a folding transform with folding matrix which is orthogonal and enables us to fold images either up-down or left-right. When an image is folded through this way repeatedly, it becomes scrambled. The experimental results demonstrate that the proposed image scrambling algorithm has effective hiding ability for image information with small computation burden as well as wide adaptability to images with different scales, and also robust under common attacks.
