Images are gaining popularity in communication, entertainment and business etc.Some images can have confidential information so the security of these confidential images is a crucial issue.There is the image encryption technique that uses a one-dimensional random scrambling and provides security to secret images.The drawback of this technique is that it does not produce different histogram from the histogram of original image even after encryption procedure and this unchanged histogram reveals useful information about the original image.In this paper, an image encryption method is proposed that eliminates this drawback and provides better security than algorithm that uses one dimensional random scrambling.
