Abstr act.With the development of information security, the traditional image encryption algorithm has been far from to ensuring the security of images in the transmission process.This paper presents a new image encryption algorithm, which can improve the security of image during transmission more effectively.The traditional scrambling algorithm based on Arnold transformation only applies to the square area, which is a big limitation.Focus on this, a multi-region algorithm for image scrambling encryption model is proposed, which splits the non-square image to multiple square regions, and scrambles each region.Experimental results show that the new algorithm improves the image security effectively to avoid deciphering, and it also can restore the image as same as the original image almost, which reaches to the purposes of image safe and reliable transmission.1 Intr oduction
