It has been far from to ensure 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. 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 decipher, and it also can restore the image almost as same as the original image, which reaches to the purposes of image safe and reliable transmission. %U http://cea.ceaj.org/EN/abstract/article_30533.shtml
