An Innovative Approach: Image Encryption with Chaotic Maps using DNA Addition Operation
M. Pradeep Raj, Shelly Garg · 2014
Encryption technology is an important measure to ensure the security of digital image, this paper's main purpose is to research how to encrypt images by chaos. In this paper, five chaotic maps are compared and noise effects are observed on image. Firstly, we use the image encryption algorithm to convert original image to encrypted image. Now we apply noise on the encrypted image and then decrypt cipher image with noise back to original image. The simulation experimental results show that Cross Chaotic map has got best results. Also, noise has a little effect on original image and can easily be received by the receiver.
