Digital Image Encryption with Discrete Fractional Transforms and Chaos: A Comparative Analysis
Information security has been most popular and important issue in the fastest growing age of communication. Therefore, various techniques for the security of image have been developed which is commonly known as image encryption techniques. Many methods have already been proposed and in this context the Fourier transform and its different fractional orders are very recent advancements in this area. In this paper, the comparative analysis is done on two methods i.e. DFrFT and DFrST with chaos function.
