A New Image Content Protection Method

This paper presents a new image content protection method. In the image scrambling for encryption, the Arnold transform often used. But Arnold transform is given only one form and it is an open form, so reducing it security. In this paper, a species that contains a lot of transform sets is presented, we call it as FAN transform. Since the type of the FAN transformation is infinite, it will increase the difficulty of cracking and improve security. In this paper, the FAN transform principle is presented, and verified the practical effect in computer.
